VANGUARD
CALIFORNIA
TAX-FREE FUND
ANNUAL REPORT
NOVEMBER 30, 1996

THE VANGUARD GROUP: LINKING TRADITION AND INNOVATION

    At Vanguard, we treasure our rich nautical heritage--even as we steer our
course toward the twenty-first century. Our Report cover reflects that blending
of tradition and innovation, of past, present, and future.  The montage
includes a bronze medallion with a likeness of our namesake, HMS Vanguard (Lord
Nelson's flagship at The Battle of the Nile); a clock built circa 1816 in
Scotland, featuring a portrait of Nelson (who is also shown, accepting a
surrender, in a detail from a nineteenth-century engraving); and several views
of our recently completed campus, which is steeped in nautical imagery--from
our buildings named after Nelson's warships (Victory, Majestic, and Goliath are
three shown), to our artwork and ornamental compass rose.

    VANGUARD HAS ALWAYS STRIVED TO BE THE STANDARD-BEARER for mutual fund
disclosure, going well beyond the "letter of the law" in our shareholder
communications. During the past year, we raised the standard once again by
rewriting and reformatting our Fund prospectuses. They are designed to ensure
that prospective investors fully understand, before they make an investment,
each Fund's investment strategies, risks, and costs. In that spirit, we have
redesigned our Annual Reports to shareholders, which provide a comprehensive
discussion and analysis of the year's results in the context of each Fund's
investment objectives and policies. Since Vanguard has long been recognized for
the quality and content of these Fund Reports, our overriding objective was to
maintain the character of the previous Reports, while adding information to
assist shareholders in understanding the investment characteristics of their
Fund. 

     THE NEW FUND REPORTS INCLUDE A MESSAGE TO SHAREHOLDERS from Chairman John
C. Bogle and President John J. Brennan. This Message continues to provide a
candid assessment of the Fund's performance relative to an appropriate
unmanaged market benchmark and a peer group of mutual funds with similar
investment policies. It also reviews the principal factors contributing to--and
detracting from--the returns earned by the Fund. To help you evaluate your
Fund's current-year performance, the Message includes a discussion of the
Fund's long-term investment results, as well as a look ahead to the prospects
for the coming year. A recap of the financial markets, which had been included
as part of the Chairman's letter, now appears in The Markets In Perspective.
This overview covers the world's financial markets, putting the results of the
Fund's strategy in a global perspective.

    THE PORTFOLIO PROFILE REPRESENTS AN ADDITION TO OUR FUND REPORTS.
In this day and age, many investors use detailed statistical information to
evaluate their mutual fund holdings, and our new Portfolio Profile furnishes
shareholders with comprehensive data on key characteristics--sector
diversification, volatility, top-ten holdings, among others--that ultimately
define how a Fund is likely to perform in various market environments. For this
information to be used effectively, we include a brief description of the
profiled characteristics. The Report From The Adviser (for our traditionally
managed Funds) now covers specific topics that we have defined as being the
important ones for the adviser to address--and we do our best to ensure that
this Report is written in the same simple and candid manner that characterizes
all Vanguard communications. Finally, each Adviser's Report will include an
inset reminder of the adviser's basic investment philosophy.

     WE TRUST THAT THIS REDESIGNED FUND REPORT will continue to meet your need
for a fair, candid, and clear presentation of your Fund's investment results 
and a thorough portfolio review. We welcome any comments that you might have 
at any time regarding these Reports.

DEAR SHAREHOLDER,

          The 1996 fiscal year for Vanguard California Tax-Free Fund, which
ended on November 30, proved notable for one important reason: Relative
stability returned to the municipal bond market for the first time in the past
four years.

     Interest rates fluctuated in a fairly narrow range during the
year--responding to marked shifts in investor sentiment about the strength of
the U.S. economy and the specter of inflation--but on balance the yield on
long-term U.S. Treasury bonds increased only slightly and the yield available
on long-term tax-exempt bonds was essentially unchanged. In this calmer
environment, the returns of our Money Market, Insured Intermediate-Term, and
Insured Long-Term Portfolios exceeded the results of their competitive fund
groups.  The table at right presents each Portfolio's twelve-month return as
well as its income and capital components.

</TABLE>

     The total return (capital change plus reinvested dividends) of the Insured
Long-Term Portfolio is based on a change in net asset value from $11.27 per
share on November 30, 1995, to $11.42 per share on November 30, 1996, adjusted
for dividends totaling $0.598 per share from net investment income. The Insured
Intermediate-Term Portfolio's return is based on a change in net asset value
from $10.44 per share on November 30, 1995, to $10.58 per share on November 30,
1996, adjusted for dividends totaling $0.508 per share from net investment
income. As expected--but is by no means guaranteed--the Money Market
Portfolio's net asset value remained at $1.00 per share. The Portfolio's yield
at the end of the fiscal year stood at 3.4%, down from 3.6% a year earlier.

FISCAL 1996 PERFORMANCE OVERVIEW

In the taxable bond market, yields experienced some interim variability, but
ended the period just a bit higher than their beginning levels. Yields on
municipal bonds remained unchanged on balance at 5.7%, as investor concerns
about the prospect of a "flat tax" all but disappeared.

     This environment of relative stability contrasted starkly with the three
previous years. During 1993, interest rates tumbled and bond prices surged,
only to reverse themselves in the rapidly rising interest-rate environment of
1994. But in 1995, a remarkable about-face in the course of interest rates sent
bond prices soaring once again. The lesson is clear: While bond (and bond fund)
prices can fluctuate sharply over short periods, these price swings tend to be
offsetting over longer periods.

     During fiscal 1996, when most municipal bond funds essentially earned
their coupons, the +6.9% annual total return for the California Insured
Long-Term Portfolio was nicely ahead of the +5.3% annual return for the average
California insured municipal

bond fund and the +5.9% return of the Lehman Municipal Bond Index. This
national Index is a tough standard for all state tax-free funds, existing, as
it does, only on paper, outside the "real world" in which operating expenses
and transaction costs are very much in evidence. The +6.4% return for the
California Insured Intermediate-Term Portfolio easily bested both the +5.0%
return for the average California intermediate-term municipal bond fund and the
+5.2% return of the Lehman 7-Year Municipal Bond Index. Our Money Market
Portfolio returned +3.3%, compared with the +2.9% return for the average
California tax-exempt money market fund.

     The table below presents a general comparison of the annual income earned
on tax-exempt and taxable securities as of November 30, 1996, assuming a
$100,000 investment. For California residents, the income earned by our
Portfolios is exempt from state, local, and federal income taxes. Given these
tax advantages, investors in the California Insured Long-Term Portfolio who are
taxed at the highest federal and state marginal tax rates can earn 78% more
after-tax income than they could in a comparable long-term taxable bond fund,
while investors in our Insured Intermediate-Term Portfolio could earn 57% more
after-tax income. For similarly situated investors in our Money Market
Portfolio, the after-tax yield premium of MIG-1 notes over U.S. Treasury bills
was 44% at the end of the twelve-month period. (Put another way, for a
California investor, a yield of 5.7% on a tax-exempt long-term portfolio would
be the equivalent of an 11.5% taxable yield; for a tax-exempt short-term yield
of 3.6%, the taxable equivalent would be 7.3%.) Our illustration assumes
current yields (as of November 30, 1996) of 6.4% for long-term U.S. Treasury
bonds, 6.0% for intermediate-term U.S. Treasury bonds, 5.1% for U.S. Treasury
bills, 5.7% for long-term municipals, 4.7% for intermediate-term municipals,
and 3.6% for short-term municipals.

Tax adjustment assumes federal tax rate of 39.6% and the top state tax rate of
11%; local taxes not considered. The illustration is not intended to represent
future results.


     Please note that these examples ignore two important quality distinctions
between state-specific municipal bond funds and U.S.  Treasury bond funds: (1)
U.S. Treasury bond funds hold solely Treasury securities, which are backed by
the full faith and credit of the U.S. government; and (2) state-specific
municipal bond funds incur a significant risk by concentrating assets in
securities from a particular economic region.

     For our Insured Long-Term and Insured Intermediate-Term Portfolios, these
added risks are substantially mitigated by private insurance, which, in effect,
guarantees the full payment of annual income and the return of principal at
maturity for the municipal bonds we hold. Portfolio insurance is generally not
available for short-term securities; thus, the task of preserving principal in
our Money Market Portfolio falls to our investment adviser, Vanguard Fixed
Income Group. The Group carefully scrutinizes the credit quality of our
holdings and  has earned our Portfolio Moody's Investor Service's highest
quality rating (or

the equivalent) for shorter-term securities. That said, we emphasize that money
market fund investments are not guaranteed by the Federal Deposit Insurance
Corporation, which insures bank accounts and certificates of deposit.

LONG-TERM PERFORMANCE OVERVIEW

The table at right compares the longer-term performance of each California
Portfolio with that of its mutual fund peer group. It also illustrates the
"Vanguard Advantage"--the performance edge our Portfolios provided over their
respective competitive standards.

     Our expense ratio advantage over our typical competitor plays a key role
in our performance advantage. Our Portfolios maintain expense ratios (expenses
as a percentage of average net assets) of 0.19%, compared with the 1.01%
charged by the average long-term state tax-free fund and 0.59% for the average
money market state tax-free fund. This benefit over our competitors has been
available to our shareholders year after year with no sacrifice in credit
quality. Vanguard Fixed Income Group also plays a key role in our success,
managing the Portfolios ably and maintaining a level of investment quality that
is, in our judgment, second to none in the field.

IN SUMMARY

The past four years have illustrated the range of market environments that bond
fund investors may enjoy--or be forced to endure.  Which of these environments
is normal for municipal bonds? The answer is probably: all of the above. In the
years ahead, there are sure to be more sharp rises in interest rates, more
sustained declines, and more years of relative tranquility. Indeed, this is
part and parcel of investing in bond funds. In the long  run, however, the rate
of interest income--"the coupon"--will be the dominant source of our returns.

     Whatever the year-to-year turbulence of the bond market, Vanguard
California Tax-Free Fund will do what it has always done: continue our focus on
providing returns that exceed those of competitive norms, even as we maintain
the highest standards of credit quality. As part of a long-term investment
program that includes stock funds, bond funds, and money market funds, the
California Tax-Free Portfolios should prove rewarding to investors.

        The Markets In Perspective: Fiscal Year Ended November 30, 1996


U.S. EQUITY MARKETS

Few investors would have expected the stock market over the past 12 months to
come close to matching the 37.0% return of the prior 12. Yet when the past two
fiscal years are considered cumulatively, the Standard & Poor's 500 Composite
Stock Price Index has risen 75.1%. Not surprisingly, many of the factors that
drove the market higher in 1995 were also in place this year. Once again,
steady economic growth and low inflation were powerful motivators.

     The equity markets were decidedly "un-equitable," however, when it came to
size and sectors. Companies with larger market values, such as those that
dominate the S&P 500 Index, prevailed. In fact, even within the Index, it was
the largest companies that turned in the best performance. The 50 biggest
companies in the S&P 500 Index (which  account for roughly half its market
value) gained 31.8% in the fiscal year ended November 30, compared with an
increase of 27.9% for the entire Index. Looking at the S&P 500 Index's
performance by sector, financial stocks were strongest, closing the year with a
41.9% gain. Technology stocks were a close second, gaining 39.3%. Utilities,
plagued early in the year by higher interest rates and a rapidly changing
competitive landscape, eked out a 4.4% return, the lowest within the Index.

     With the largest companies performing so well, it was difficult for
smaller issues to keep pace. This was evidenced in the considerable difference
between the 27.9% return of the S&P 500 Index and the 16.5% return of the
Russell 2000 Small Stock Index.  Even for the smaller companies, there was a
significant range of performance among sectors. Energy stocks led the Russell
2000 Index with a 77.0% gain for the year. Here, rising prices, limited
exposure to the cyclical refining business, and a reduced number of competitors
created a favorable environment for the stocks. At the other end of the
spectrum were health-care stocks, which showed a loss of -0.4%.

U.S. FIXED-INCOME MARKETS

As the fiscal year ended, the 30-year U.S. Treasury yield of 6.4% was modestly
higher than its 6.1% level on November 30, 1995. The relatively small
difference in these figures belies the turmoil endured by the fixed-income
markets over the past 12 months.

     When the fiscal year began, "Steady as she goes" was the common wisdom.
Modest economic growth and benign inflation were expected to continue, giving
the Federal Re-

serve no reason to move interest rates higher. That complacency was shattered
by an exceptionally strong February jobs report, the first of what turned out
to be a succession of signs that in fact the economy was growing at a much
faster--and potentially inflation-inducing--pace. The bond market reacted
swiftly to compensate for the perceived risk: The 30-year Treasury yield jumped
from just below 6.0% in late December to 6.7% in late March. The next several
months saw a consistent pattern in which bond yields rose on the Friday of the
jobs-report release only to fall back by the middle of the month. In reality,
there was little bite to the bark. Inflation, as measured by the Consumer Price
Index, remained near an annualized rate of 3.2%. And, as the fiscal year
entered its final quarter, evidence once again pointed to more "acceptable"
levels of growth. That--plus the market's satisfaction with the national
election results and prospects for budget action--helped bonds finish the
fiscal year with a strong rally.

     The rally enabled the longer-maturity sectors of the market to overcome
performance deficits and finish the year with positive returns. Although the
specter of the Federal Reserve Board loomed large during the year, in fact the
Board acted only twice, lowering the federal funds rate by a total of 0.5%.

     Corporate bonds, mortgage-backed issues, and municipals were three
relatively bright spots over the past year. The strength in earnings that
benefited stock prices extended to the corporate bond sector as well. These
bonds, especially those of lower credit quality, performed well relative to
Treasuries as there appeared to be little risk of skipped interest payments or
bankruptcy against the good earnings backdrop. The stable-to-rising
interest-rate environment throughout most of the year benefited another large
segment of the bond market--mortgages--as the threat of refinancings receded.
Finally, municipal bonds outpaced their U.S.  Treasury counterparts. The sector
was shielded to a certain extent from the inflation wars of the Treasury
market, and demand outstripped supply for much of the year.

INTERNATIONAL EQUITY MARKETS

Concern about U.S. Federal Reserve Board policy appeared to drive global
markets as much as it did those in the United States. In aggregate, the markets
rose 17.0%, as measured by the Morgan Stanley Capital International-Europe,
Australasia, Far East Index. A stronger dollar reduced this return to 12.1% for
U.S.-based investors.

     Regionally, Europe's 22.9% return overshadowed the 1.4% generated by the
Pacific Basin. Europe's major markets continued to work toward the economic
targets that must be attained by 1999 under the Maastricht Treaty. This
ongoing, albeit bumpy, effort kept the continent's economic growth modest and
gave investors confidence. The Pacific region, of course, was dominated by the
influence of the Japanese market. Despite evidence of a strengthening economy
early in the year, Japan's market was shadowed by lingering problems in the
banking and real estate sectors and by tepid interest on the part of Japanese
investors. The dollar's appreciation against the yen had a significant impact
on returns, turning the year's 7.1% gain in yen into a -4.5% loss in dollars.
In contrast, the returns for a number of other countries in the  region were
quite strong: for example, Hong Kong, 38.2%, and Malaysia, 31.8% (in U.S.
dollars).

REPORT FROM THE ADVISER

[PHOTO]

      Yields on tax-exempt securities decreased slightly while yields on
short-term securities ended virtually unchanged in the 12 months ended November
30, 1996, the fiscal year for Vanguard California Tax-Free Fund.

THE INSURED PORTFOLIOS

Over the 12 months, the yield on high-grade, long-term municipal bonds declined
by 8 basis points, or 0.08 percentage point, from 5.74% to 5.66%. By way of
comparison, the yield on the benchmark 30-year U.S. Treasury bond increased by
22 basis points, from 6.13% to 6.35%. However, these relatively small changes
obscure the volatility in both markets during the course of the year.

     During the first half, reports of a solid increase in economic activity
and robust employment gains fanned fears of inflation.  In reaction, by June
the fixed-income market had driven up the yields on the 30-year Treasury bond
and on long-term, high-grade municipal bonds to 7.19% and 6.22%, respectively.
But as the economy cooled from its earlier torrid pace, investors grew more
confident that the Federal Reserve Board would not have to tighten monetary
policy, and yields fell back nearly to their levels at the start of the year.

     For municipal bonds, the issue of tax reform grew in importance in early
1996. Various flat-tax proposals either directly or indirectly threatened the
tax-exempt privilege of municipal securities. In its basic form, a flat tax
would reduce the current hierarchy of income-tax rates to only one lower level
for all earned income. Unearned income (interest, dividends, and capital gains)
would not be taxed at all. Since all interest would be exempt from federal
income tax, municipal bond interest payments would no longer offer a special
tax benefit. Early in the fiscal year, concern about such proposals caused the
prices of municipal bonds to fall relative to those of taxable bonds, enabling
municipal investors to purchase high-grade, tax-exempt bonds with attractive
yields--as high as 94% of comparable U.S. Treasury obligations.

     However, as a campaign issue, the complete overhaul of the federal tax
system bombed by early summer. The flat tax suffered a peaceful demise upon the
nomination of Bob Dole and was effectively buried with the reelection of
President Clinton. By the end of the year, with the flat-tax trauma a thing of
the past, the ratio of tax-exempt yields to taxable yields fell to 89%. The
relative outperformance of municipals came despite an increase late in the year
in the supply of new tax-exempt bond issues, which raised the
tax-exempt/taxable yield ratio from a low of 84% in August.

     For 1996, the Insured Long-Term and Insured Intermediate-Term Portfolios
provided positive rates of return, roughly commensurate with the dividends
derived from interest income on the Portfolios. Because market yields changed
only slightly over the year, income was the dominant component of total return.
In this environment, Vanguard's low expense ratio



INVESTMENT PHILOSOPHY

The Fund reflects a belief that it can achieve a high level of current income,
consistent with each Portfolio's stated maturity and stringent quality targets,
that is exempt from federal and California income taxes by investing in insured
and high-quality uninsured securities issued by state, county, and municipal
governments in California.





                                       6

provided a powerful advantage in maximizing the tax-exempt return to
shareholders. The lower expense ratio allows more investment income to flow
directly to shareholders, which translates into higher Portfolio returns. Over
time, this has the powerful and enduring effect of contributing to superior
performance.

     Looking ahead, we believe that the tax-exempt investment arena will
continue to provide above-average value to shareholders who seek a high-quality
investment with durable and attractive after-tax returns. This is especially
true for our State Tax-Free Portfolios, which offer the extra benefit of income
that is exempt from state, as well as federal, taxes.

THE MONEY MARKET PORTFOLIO

Among money market segments, stable Federal Reserve policy during the second
half of the fiscal year allowed yields on U.S. Treasury bills and municipal
notes to move somewhat lower. The yields on one-year municipal notes declined
by 15 basis points during the second half, while yields on one-year U.S.
Treasury bills fell 35 basis points. Aside from the Fed's stable policy, two
issues had a significant impact on the short-term securities market.

     The first was the onset of the traditional spring/summer municipal
borrowing season. This seasonal deluge of new short-term issues created a
temporary summertime overabundance of municipal notes and bonds in the market.
The excess supply caused a dramatic rise in yields during late July and August
(though in late September yields commenced a steady downward movement). We took
advantage of the opportunity to extend the average maturities of the Money
Market Portfolio, thereby locking in higher yields. Additionally, we further
diversified the Portfolio, thereby further spreading credit risk.

     The second big influence on the market was the Securities and Exchange
Commission's decision to postpone the effective date for changes to its Rule
2a-7 under the Investment Company Act of 1940. This rule governs the credit and
maturity risk of money market funds. Under the proposed changes, regulations
would be tightened on tax-exempt money market funds so as to increase the
likelihood of their maintaining a stable net asset value. The changes were
expected to take effect on June 3, 1996, but the mutual  fund industry made the
SEC aware of the need for numerous technical amendments, and the deadline was
therefore postponed. We anticipate that new regulations will be completed and
made mandatory by the second quarter of 1997. Competing funds that operate
under lower quality standards than Vanguard will need to alter their fund
management policies. Vanguard's tax-exempt money market Portfolios, however,
have always been managed in a conservative, quality-oriented manner, and we
anticipate minimal impact when the new regulations take effect.

     In summary, the coming months will require vigilance. Market participants
will be required to adopt more stringent regulations at a time when tax-exempt
assets are growing and the supply of new issues is minimal. Vanguard's
conservative management style will give the Money Market Portfolio a strategic
advantage as stricter regulations dictate that competitors play catch-up in
terms of quality.

AVERAGE COUPON. The average interest rate, expressed as a percentage of face
value, paid on the securities held by a portfolio.  Average Duration. An
estimate of how much a portfolio's share price will fluctuate in response to a
change in interest rates. To estimate the price sensitivity of a portfolio,
multiply its duration by the change in rates. If interest rates rise by one
percentage point, the share price of a portfolio with an average duration of
five years would decline by about 5%. If rates decrease by a percentage point,
the portfolio's share price would rise by 5%.

AVERAGE MATURITY. The average length of time until bonds held by a portfolio
reach maturity and are repaid. In general, the longer the average maturity, the
more a portfolio's share price will fluctuate in response to changes in market
interest rates.

AVERAGE QUALITY. An indicator of credit risk, this figure is the average of the
credit ratings assigned to the portfolio's securities holdings by credit-rating
agencies. Agencies assign credit ratings after appraising an issuer's ability
to meet its debt obligations. Quality is graded on a scale, with Aaa indicating
the most creditworthy bond issuers and MIG-1 indicating the most creditworthy
issues of municipal money market securities. (Individual money market
securities with a rating of A, Aa, and Aaa all receive a MIG-1 designation.)

BETA. A measure of the magnitude of a portfolio's past share-price fluctuations
in relation to the fluctuations in the overall market (or appropriate market
index). The market, or index, has a beta of 1.00, so a portfolio with a beta of
1.20 would have seen its share price rise or fall by 12% when the overall
market rose or fell by 10%.

DISTRIBUTION BY CREDIT QUALITY. An indicator of the risk of default or other
credit problems on securities held by the portfolio.

DISTRIBUTION BY MATURITY. An indicator of interest-rate risk. In general, the
higher the concentration of longer-maturity issues, the more a portfolio's
share price will fluctuate in response to changes in interest rates. Callable
securities trading at a premium to par value are treated as coming due on their
earliest redemption date.

EXPENSE RATIO. The percentage of a portfolio's average net assets used to pay
its annual administrative and advisory expenses. These expenses directly reduce
returns to investors. The average expense ratio in 1995 for state tax-free bond
funds was 1.01%; for state tax-free money market funds, the figure was 0.59%.

INVESTMENT FOCUS. This grid indicates the focus of a portfolio in terms of two
attributes: average maturity (short, medium, or long) and average credit
quality (high, medium, or low).

NUMBER OF ISSUES. An indicator of diversification. The more separate issues a
portfolio holds, the less susceptible it is to a price decline stemming from
the problems of a particular issue.

R-SQUARED. A measure of how much of a portfolio's past returns can be explained
by the returns from the overall market (or its benchmark index). If a
portfolio's total return were precisely synchronized with the overall market's
return, its R-squared would be 1.00. If a portfolio's returns bore no
relationship to the market's returns, its R-squared would be 0.

YIELD. A snapshot of a portfolio's interest income. The yield, expressed as a
percentage of a portfolio's net asset value, is based on income earned by the
portfolio over the past 30 days (7 days for money market portfolios) and is
annualized, or projected forward for the coming year.

YIELD TO MATURITY. The rate of return an investor would receive if the
securities held by a portfolio were held to their maturity dates.

PERFORMANCE SUMMARY: MONEY MARKET PORTFOLIO

All of the data on this page represent past performance, which cannot be used
to predict future returns that may be achieved by the Portfolio. Note, too,
that returns can fluctuate widely. An investment in a money market fund is
neither insured nor guaranteed by the U.S. government, and there is no
assurance that the fund will be able to maintain a stable net asset value of
$1.00 per share.

FINANCIAL STATEMENTS
NOVEMBER 30, 1996

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each Portfolio's municipal bond
holdings, including each security's market value on the last day of the
reporting period and information on credit enhancements (insurance or letters
of credit). Securities are grouped and subtotaled according to their insured or
non-insured status. Other assets are added to, and liabilities are subtracted
from, the value of Total Municipal Bonds to calculate the Portfolio's Net
Assets. Finally, Net Assets are divided by the outstanding shares of the
Portfolio to arrive at its share price, or Net Asset Value (NAV) Per Share.

    At the end of the Statement of Net Assets, you will find a table displaying
the composition of the Portfolio's net assets on both a dollar and per-share
basis. Undistributed Net Investment Income is usually zero because the
Portfolio distributes its net income to shareholders as a dividend each day.
Any realized gains must be distributed annually, so the bulk of net assets
consists of Paid in Capital (money invested by shareholders). The balance shown
for Accumulated Net Realized Gains usually approximates the amount available to
distribute to shareholders as taxable capital gains as of the statement date,
but may differ because certain investments or transactions may be treated
differently for financial statement and tax purposes. Any Accumulated Net
Realized Losses, and any cumulative excess of distributions over net realized
gains, will appear as negative balances.

Unrealized Appreciation (Depreciation) is the difference between the value of
the Portfolio's investments and their cost, and reflects the gains (losses)
that would be realized if the Portfolio were to sell all of its investments at
their statement-date values.

STATEMENT OF OPERATIONS

This Statement shows interest earned by each Portfolio during the reporting
period, and details the operating expenses charged to the Portfolio. These
expenses directly reduce the amount of investment income available to pay to
shareholders as tax-exempt income dividends. This Statement also shows any Net
Gain (Loss) realized on the sale of investments, and the increase or decrease
in the Unrealized Appreciation (Depreciation) on investments during the period.
If a Portfolio invested in futures contracts during the period, the results of
these investments are shown separately.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each Portfolio's total net assets changed during the
two most recent reporting periods. The Operations section summarizes
information that is detailed in the Statement of Operations. Because the
Portfolio distributes its income to shareholders each day, the amounts of
Distributions--Net Investment Income generally equal the net income earned as
shown under the Operations section. The amounts of Distributions--Realized
Capital Gain may not match the capital gains shown in the Operations section,
because distributions are determined on a tax basis and may be made in a period
different from the one in which the gains were realized on the financial
statements. The Capital Share Transactions section shows the amount
shareholders invested in the Portfolio, either by purchasing shares or by
reinvesting distributions, and the amounts redeemed. The corresponding numbers
of Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes each Portfolio's investment results and distributions to
shareholders on a per-share basis. It also presents the Portfolio's Total
Return and shows net investment income and expenses as percentages of average
net assets. These data will help you assess: the variability of the Portfolio's
net income and total returns from year to year; the relative contributions of
net income and capital gains to the Portfolio's total return; how much it costs
to operate the Portfolio; and the extent to which the Portfolio tends to
distribute capital gains.

  The table also shows the Portfolio Turnover Rate, a measure of trading
activity. A turnover rate of 100% means that the average security is held in
the Portfolio for one year. Money market portfolios do not show a Portfolio
Turnover Rate because securities purchased with less than one year to maturity
are excluded from the calculation of turnover rates.

NOTES TO FINANCIAL STATEMENTS

Vanguard California Tax-Free Fund is registered under the Investment Company
Act of 1940 as an open-end investment company, or mutual fund, and comprises
the Insured Long-Term, Insured Intermediate-Term, and Money Market Portfolios.
Each Portfolio invests in debt instruments of municipal issuers whose ability
to meet their obligations may be affected by economic and political
developments in the state of California.

A.   The following significant accounting policies conform to generally
accepted accounting principles for mutual funds. The Fund consistently follows
such policies in preparing its financial statements.

     1. SECURITY VALUATION: Money Market Portfolio: investment securities are
valued at amortized cost, which approximates market value. Other Portfolios:
Bonds, and temporary cash investments acquired more than 60 days to maturity,
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities,
and credit ratings), both as furnished by independent pricing services. Other
temporary cash investments are valued at amortized cost, which approximates
market value.

     2. FEDERAL INCOME TAXES: Each Portfolio intends to continue to qualify as
a regulated investment company and distribute all of its income. Accordingly,
no provision for federal income taxes is required in the financial statements.

     3. FUTURES CONTRACTS: The Insured Long-Term and Insured Intermediate-Term
Portfolios may use Municipal Bond Index, U.S.  Treasury Bond, and U.S. Treasury
Note futures contracts, with the objectives of enhancing returns, managing
interest-rate risk, maintaining liquidity, diversifying credit risk and
minimizing transaction costs. The Portfolios may purchase or sell futures
contracts instead of bonds to take advantage of pricing differentials between
the futures contracts and the underlying bonds. The Portfolios may also seek to
take advantage of price differences among bond market sectors by simultaneously
buying futures (or bonds) of one market sector and selling futures (or bonds)
of another sector. Futures contracts may also be used to simulate a fully
invested position in the underlying bonds while maintaining a cash balance for
liquidity. The primary risks associated with the use of futures contracts are
imperfect correlation between changes in market values of bonds held by the
Portfolios and the prices of futures contracts, and the possibility of an
illiquid market.

     Futures contracts are valued based upon their quoted daily settlement
prices. The aggregate principal amounts of the contracts are not recorded in
the financial statements. Fluctuations in the value of the contracts are
recorded in the Statement of Net Assets as an asset (liability) and in the
Statement of Operations as unrealized appreciation (depreciation) until the
contracts are closed, when they are recorded as realized futures gains
(losses).

     4. DISTRIBUTIONS: Distributions from net investment income are declared
daily and paid on the first business day of the following month. Annual
distributions from realized capital gains, if any, are recorded on the
ex-dividend date.

     5. OTHER: Security transactions are accounted for on the date securities
are bought or sold. Costs used to determine realized gains (losses) on the sale
of investment securities are those of the specific securities sold. Premiums
and original issue discounts are amortized and accreted, respectively, to
interest income over the lives of the respective securities.

B.   The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to the Fund under methods approved by the Board of
Trustees. At November 30, 1996, the Fund had contributed capital aggregating
$258,000 to Vanguard (included in Other Assets), representing 1.3% of
Vanguard's capitalization. The Fund's trustees and officers are also directors
and officers of Vanguard.

C.   The Fund's investment adviser may direct new issue portfolio purchases,
subject to obtaining the best price and execution, to underwriters  who have
agreed to rebate or credit to the Fund part of the underwriting fees generated.
Such rebates or credits are used solely to reduce the Fund's administrative
expenses. The Fund's custodian bank has also agreed to reduce its fees when the
Fund maintains cash on deposit in the non-interest-bearing custody account. For
the year ended November 30, 1996, directed brokerage and custodian fee offset
arrangements reduced expenses by:

REPORT OF INDEPENDENT ACCOUNTANTS


To the Shareholders and
Board of Trustees of
Vanguard California Tax-Free Fund

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Insured Long-Term Portfolio, Insured Intermediate-Term Portfolio, and Money
Market Portfolio (constituting Vanguard California Tax-Free Fund, hereafter
referred to as the "Fund") at November 30, 1996, and the results of each of
their operations, the changes in each of their net assets and the financial
highlights for each of the periods indicated, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at November 30, 1996 by
correspondence with the custodian and the application of alternative auditing
procedures, provide a reasonable basis for the opinion expressed above.
