                               CHAIRMAN'S LETTER


DEAR SHAREHOLDER:

During the six months ended May 31, 1995--the first half of the fiscal year for
Vanguard State Tax-Free Portfolios--a fairly substantial decline in long-term
interest rates resulted in higher prices for long-term tax-exempt bonds. These
price increases pushed the six-month total returns (capital change plus income)
of all our Insured Longer-Term Portfolios well into double-digit territory.
While long rates declined during the past six months, shorter-term interest
rates actually increased marginally. In this environment, the yields of our
Money Market Portfolios increased nicely and remained comfortably ahead of the
yields offered by comparable funds.

THE STATE INSURED LONG-TERM PORTFOLIOS

In the wake of repeated interest rate increases by the Federal Reserve during
1994, long-term municipal bond yields peaked in November 1994 at 7.1%. As these
rate hikes seemed to slow the economy's growth, concerns about future inflation
were allayed, and rates began to decline. By the end of May, municipal bond
yields had fallen to 5.8%, a decline of 130 basis points.

         In this environment, longer-term municipal bond funds enjoyed
outstanding returns. Indeed, each of Vanguard's Insured Long-Term Portfolios
provided six-month total returns (capital change plus income) in the area of
+14%. This sharp price rally overwhelmed the negative returns of the prior six
months, bringing our total returns for the twelve months strongly into positive
territory. Although fluctuating net asset values are part and parcel of bond
fund investing, the recent swings in market value demonstrate the benefit of
remaining committed to a long-term investment strategy.

         The table opposite shows the Longer-Term Portfolios' twelve-month
returns, reflecting a full year's income. To provide some perspective on how
fluctuating interest rates have impacted our Insured Longer-Term Portfolios
over this period, the table breaks down our Portfolios' total returns into
their income and capital components. I would emphasize that the table conceals
the fact that the full period was composed of two vastly different six-month
sub-periods, one in which returns were sharply negative, the other strongly
positive.

</TABLE>

The current tax-exempt yields on our Insured Longer-Term Portfolios are
presently in the area of 5.2%, compared with 6.3% six months ago. The yield for
each Portfolio is presented in the table on page 3 of this report, which also
includes per share net asset values, dividends, and total returns over the past
six and twelve months.

THE STATE MONEY MARKET PORTFOLIOS

As noted earlier, the Federal Reserve Board has remained relatively
tight-fisted in its monetary policy during the past six months, bringing some
stability to money market yields. This stability is a stark contrast to fiscal
1994, when the Board raised the Fed funds rate (at which banks borrow from one
another) on fully six separate occasions. It would appear that the Fed's tough
policy is bearing fruit: inflation so far remains quite subdued, and business
activity has slowed to a more normal growth rate.

         While rates have been stable in recent months, the table below shows
the impact of the dramatic surge in short-term rates on our annualized yields
over the past year and one-half. You will note that, during this period, the
yields on our Money Market Portfolios have risen by more than 60%.

Regardless of future interest rate movements, the yield advantage of our
Vanguard State Money Market Portfolios is virtually certain to remain
attractive relative to other comparable money market funds. The principal
reason for this advantage, as you know, is that our operating expenses are so
much lower than industry norms. Our Portfolios, for example, operate at an
annual expense ratio of about 0.2%, compared with 0.6% for our average
competitor. This advantage of 0.4% carries directly to the bottom line: the
yield you receive. Thus, in a market in which gross yields are, say, 4.0%, our
Portfolios should provide a net yield of 3.8%, compared with 3.4% for other
comparable money market portfolios.

         I want to underscore that our higher yields do not arise from the
ownership of lower quality money market instruments.  The quality of our
Portfolios is, we believe, as high as any tax-exempt money market fund in the
field. Funds which stinted on quality last year ran the risk that their net
asset values might fall below the $1.00 value that investors have come to take
for granted. Our focus on quality--along with, we acknowledge, some good
luck--spared us the consequences of this risk, and we owned no direct
obligations of Orange County, California, the most troubled credit of the
period. Each of our Money Market Portfolios' net asset values remained at $1.00
per share, which as you know, is our objective, but is not guaranteed.

IN SUMMARY

The recent swings in total returns we have witnessed help to demonstrate that
"staying the course"--even in the face of turbulent markets--will more often
than not lead to a successful long-term investment program. In contrast,
attempting to jump into and out of mutual funds in hopes of timing the
movements of the market is almost certain to result in failure.

         Whether rates remain volatile or not, the benefits of investing in
Vanguard State Tax-Free Portfolios endure: high quality, low cost, and
professional management. Along with these advantages, the Portfolios distribute
income that is 100% exempt from both Federal and state income taxes. Together,
these factors should ensure our ability to provide shareholders with efficient
and effective Portfolios in the years to come.

         I look forward to reporting to you on our results for the full year in
our 1995 Annual Report six months hence.

Sincerely,

/s/ JOHN C. BOGLE

A FEW WORDS ABOUT POSSIBLE CHANGES IN THE TAX LAW

The uncertainties related to a variety of new tax proposals seem to have
unnerved some participants in the tax-exempt bond market.  Of the options which
have been considered, perhaps the most significant to municipal bond investors
is the "flat tax." Indeed, under one proposed version, municipal bond yields
would have no advantage over taxable yields. Because of this uncertainty, the
rise in municipal bond prices has been significantly less than the rise in U.S.
Treasury bond prices over the past few months.

         As a result, the current yield on high-quality long-term municipal
bonds is 94% of the yield on taxable U.S. Treasuries giving municipal bonds
their largest after-tax yield advantage in recent years. What this means is
that an investor in the highest marginal tax bracket (40%) would earn an
after-tax yield of about 3.8% on a U.S. Treasury bond (60% of 6.4%). A
high-grade municipal bond, on the other hand, would provide a tax-exempt yield
of 6.0%--fully 58% higher. Thus, it would appear that tax uncertainty has
created unusual yield opportunity.

         In any event, the flat tax option is no longer high on the legislative
agenda, and neither of the tax bills adopted by the Senate or the House of
Representatives would disturb the existing tax-exempt status of municipal bond
interest. Until the details of any tax law changes become clearer, we would
caution municipal bond investors to give careful consideration before making
any shifts in their holdings of municipal bonds. In the meantime, we will keep
you abreast of our views on the possible effects of any proposed legislation
that could materially impact the tax status of your holdings in Vanguard
municipal bond funds.

                       REPORT FROM THE INVESTMENT ADVISER

Two significant events occurred during the first six months of the fiscal year.
The first was the stunning market rally that drove long-term municipal yields
approximately -1.1 percentage points lower. The second was the turmoil
surrounding the bankruptcy of Orange County, California.

MONEY MARKETS

The aggressive tightening of monetary policy by the Federal Reserve Board in
1994 slowed down dramatically in the first half of fiscal year 1995. The only
intervention occurred on February 1, 1995, when the Federal Reserve Board
increased the discount and Federal funds rates 0.5%. Participants in the
short-term municipal market reacted favorably to this relative stability in
interest rates and 1-year notes rallied roughly +1%. While yields on 1-year
notes declined, yields on shorter-term variable rate instruments moved in the
opposite direction, resulting in what is known as a flattening of the
short-term municipal yield curve.  The average weighted maturity of the
California Tax-Free Money Market Portfolio was positioned at the lower end of
the maturity spectrum, and consequently, benefited from this flattening. During
the fiscal half, the average monthly yield on all non-institutional state
specific money funds rose +0.78%.

         In the upcoming months, increased supply of short-term municipal
issuance should present an opportunity for the Money Market Portfolio to extend
its average maturity, but not at the expense of sacrificing quality.

BOND MARKETS

For the first half of the fiscal year, investors pushed long-term interest
rates lower as economic indices pointed increasingly to slower domestic
economic growth. Investors viewed the slowing as beneficially affecting
inflation. Long-term interest rates declined for virtually the entire six
months. For example, the benchmark 30-year U.S. Treasury bond began the fiscal
year yielding 8.0%, and by the end of May, the yield had fallen -1.4% to 6.6%.
Long-term tax-exempt bond yields followed suit, however, not in quite the same
magnitude as the taxable market. The Bond Buyer 20 Municipal Bond Index yield
declined -1.1% (from 6.9% to 5.8%) over the same period.

         The California Insured Intermediate- and Long-Term Portfolios
performed well over the six-month period. The Portfolios benefited from an
extension in their average weighted maturity that began in the fourth quarter
of the last fiscal year.  Additionally, the Portfolios' structure, with
superior protection from early calls, aided in maintaining the price
responsiveness of the Portfolios during the market rally.

         Looking ahead there are three main strategies that we expect to pursue
regarding the management of the money invested in the California Insured
Intermediate- and Long-Term Portfolios. The first is a continued focus on
improvements in call protection to enhance the durability of dividends; second
is investing to minimize taxable capital gains distributions when it does not
interfere with superior total return potential; and third is a focus on higher
coupon bonds that would position the Portfolios more defensively should
interest rates reverse direction and move higher.

ORANGE COUNTY

THE BANKRUPTCY. During the afternoon of December 1, 1994, reports began to
appear in the media that Orange County, California, had experienced massive
losses from its investment pool in the range of $1.5 billion. Several days
later, a news conference convened by county officials confirmed the losses. On
December 6, acting to prevent creditors from forcing the county to become
insolvent, the officials filed for bankruptcy protection under Chapter 9 of the
Federal Bankruptcy Code. This was the first municipal bankruptcy filing by a
major government since the Great Depression. If plans for a financial rescue of
the county are not completed before the end of June 1995, a series of defaults
could occur which would rival the $2.5 billion default by the Washington Public
Power Supply System in 1984. Importantly, Vanguard has no direct exposure to
losses stemming from Orange County.

         How this debacle happened is still being discussed and investigated.
Orange County Treasurer Robert L. Citron managed about $7.5 billion of





                                       5

County and other governments' money, and used reverse repurchase agreements to
leverage the portfolio to roughly three times the value of the underlying
investments. He then invested about a quarter of the pool in exotic derivative
securities. As rates rose rapidly during 1994, the portfolio suffered massive
unrealized market value losses. None of this was disclosed to investors.
Citron has pleaded guilty to a number of violations of California law, and
numerous Federal and state legislative and regulatory investigations are
continuing.

         POST BANKRUPTCY EVENTS. Under the direction of the bankruptcy court,
the County hired Salomon Brothers to liquidate the pool. The value of the pool
dropped from $7.6 billion to $5.9 billion, a loss of $1.7 billion, or 22%.
Those affected by the losses include the pool participants, County residents,
and investors.

         Regarding County residents, pool losses and investment income
shortfalls require a reduction in locally funded programs by 40%, resulting in
a loss of nearly 3,000 County employees (out of 15,000). Residents are to vote
on June 27 on a proposal to increase the County sales tax by one-half cent.

         As for investors, some defaults (mainly "technical" in nature) have
already resulted from the County's bankruptcy.  However, the most serious
problems lie in repayments of five note issues maturing between June 30 and
August 15, 1995, totaling $975 million. Some debt restructuring is likely to
occur. However, the County is unlikely to fully pay all interest and principal
when due. As a last resort, the County may attempt to repudiate some of its
debt. The State of California may also intervene. The outcome for investors
holding Orange County Notes cannot be predicted at present.

         The Vanguard California Tax-Free Money Market Portfolio had no
exposure to any unenhanced Orange County Notes.  Nevertheless, the aftershock
of the bankruptcy extended well beyond the boundaries of California, and
consequently, all municipal money market funds experienced its effects. The
immediate reaction in the short-term municipal market resulted in a rise in
yields of 0.75 percentage points on all general market notes. Orange County Tax
and Revenue Anticipation Notes, and any related credits, faced a much more
severe crisis since there was virtually no bid for these securities. Since
then, liquidity for general market notes has returned, and yields have rallied
through their December levels. However, illiquidity persists for Orange County
investors as bondholders negotiate payment on the notes that are due in July.

         The Orange County bankruptcy underscores the benefit of the additional
layer of credit protection provided by the AAA-rated insurance policies
attached to the bonds that are owned by the California Insured Intermediate-
and Long-Term Portfolios. As the bankruptcy story unfolded, most uninsured
Orange County investment pool related bonds were quite illiquid. In contrast,
while insured Orange County related bonds underperformed other insured bonds by
three points, the market was liquid. By late December, much of that
underperfomance had disappeared, and at the end of the fiscal half, insured
Orange County related bonds were trading at prices just slightly lower than
other insured bonds.

CONCLUSION

The Orange County bankruptcy has reinforced our commitment to rigorous credit
evaluation of the municipal securities in which we invest. This conservative
approach to assessing credit quality combined with Vanguard's low expenses
provides a high-quality investment that is exempt from both Federal and
California State income taxes.

                         NOTES TO FINANCIAL STATEMENTS

Vanguard California Tax-Free Fund is registered under the Investment Company
Act of 1940 as an open-end investment company and consists of 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 are in conformity with
generally accepted accounting principles for investment companies. Such
policies are consistently followed by the Fund in the preparation of financial
statements.

1. SECURITY VALUATION: Money Market Portfolio: investment securities are stated
   at amortized cost which approximates market value.  Other Portfolios:
   municipal bonds are valued utilizing primarily the latest bid prices or, if
   bid prices are not available, on the basis of valuations based on a matrix
   system (which considers such factors as security prices, yields, maturities
   and ratings), both as furnished by an independent pricing service.

2. FEDERAL INCOME TAXES: Each Portfolio of the Fund 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: The Insured Long-Term and Insured Intermediate-Term Portfolios
   utilize Municipal Bond Index, U.S. Treasury Bond, and U.S. Treasury Note
   futures contracts to a limited extent, with the objectives of enhancing
   returns, managing interest rate risk, maintaining liquidity, diversifying
   credit risk and minimizing transaction costs. The Portfolios may purchase
   futures contracts instead of municipal bonds when futures contracts are
   believed to be priced more attractively than municipal 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. Fluctuations in the values of futures contracts are
   recorded as unrealized appreciation (depreciation) until terminated at which
   time realized gains (losses) are recognized. Unrealized appreciation
   (depreciation) related to open futures contracts is required to be treated
   as realized gain (loss) for Federal income tax purposes.

4. DISTRIBUTIONS: Distributions from net investment income are declared on a
   daily basis payable on the first business day of the following month. Annual
   distributions from realized gains, if any, are recorded on the ex-dividend
   date. Capital gain distributions are determined on a tax basis and may
   differ from realized capital gains for financial reporting purposes due to
   differences in the timing of realization of gains.

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