Item 1. Report to Shareholders.

The Trust's semi-annual report transmitted to shareholders pursuant to
Rule 30e-1 under the Investment Company Act of 1940 is as follows:

       Welcome, Shareholder

       In this report, you'll learn about how your investment in Van Kampen
       Municipal Opportunity Trust II performed during the semiannual period.
       The portfolio management team will provide an overview of the market
       conditions and discuss some of the factors that affected investment
       performance during the reporting period. In addition, this report
       includes the trust's financial statements and a list of trust investments
       as of April 30, 2004.

       Market forecasts provided in this report may not necessarily come to
       pass. There is no assurance that the trust will achieve its investment
       objective. Trusts are subject to market risk, which is the possibility
       that the market values of securities owned by the trust will decline and
       that the value of trust shares may therefore be less than what you paid
       for them. Accordingly, you can lose money investing in this trust.

       Income may subject certain individuals to the federal Alternative Minimum
       Tax (AMT).

Past performance is no guarantee of future results. Investment return, net asset
value (NAV) and common share market price will fluctuate and trust shares, when
sold, may be worth more or less than their original cost.

As a result of recent market activity, current performance may vary from the
figures shown. For more up-to-date information, please visit vankampen.com or
speak with your financial advisor. NAV per share is determined by dividing the
value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding. The common share
market price is the price the market is willing to pay for shares of the trust
at a given time. Common share market price is influenced by a range of factors,
including supply and demand and market conditions. Total return assumes an
investment at the beginning of the period, reinvestment of all distributions for
the period in accordance with the trust's dividend reinvestment plan, and sale
of all shares at the end of the period.

Trust Report

FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2004

Van Kampen Municipal Opportunity Trust II is managed by the adviser's Municipal
Fixed Income team.(1) Current members include Timothy D. Haney, Vice President;
Robert Wimmel, Vice President; and John Reynoldson, Executive Director.

MARKET CONDITIONS

The state of the U.S. economy remained mixed over the six-month period under
review. On the positive side, economic growth continued to be robust, with Gross
Domestic Product growth topping 4 percent in both the last quarter of 2003,
preliminarily, and the first quarter of this year. While this strength in output
has historically triggered fears of rising interest rates, yields remained
stubbornly low across the municipal curve. These low yields were partly the
result of the continued low levels of observed inflation in the U.S. economy.
Unfortunately, they also reflected continuing weakness in the job market, which
remained soft throughout most of the period. The soft job numbers, coupled with
persistently low inflation, led the Federal Open Market Committee (the Fed) to
maintain its accommodative stance throughout the period.

The surprisingly rapid job growth data released in April, coupled with rapidly
rising commodity and high oil prices, led many investors to fear that the Fed
would be forced to raise interest rates earlier than the market initially
expected. As a result, bond yields across all major sectors spiked in April.

Supply of new municipal bonds in calendar 2003 hit record levels as
municipalities moved to take advantage of historically low interest rates. Many
cities and states sought to reduce expenditures by refinancing existing debt and
replacing it with lower-yielding bonds. In other cases, municipalities attempted
to meet current and future funding needs by issuing new debt. This activity
slowed in the first months of 2004.

The low interest rates that prevailed over much of the period also had an impact
on the demand for municipal bonds. Retail and institutional investor activity
slowed as holders of municipal bonds saw little reason to sell bonds purchased
at higher yield levels and reinvest at lower yields. However, the period was
marked by rising activity among non-traditional investors, such as hedge funds
and insurance companies seeking to take advantage of the attractiveness of
municipal bonds relative to some taxable securities. Additionally, investors'
search for yield led to significant outperformance by lower-rated bonds with
greater credit risk. Sectors such as health care, with a preponderance of
lower-rated issues, performed particularly well.

PERFORMANCE ANALYSIS

Closed-end fund returns can be calculated based upon either the market price or
the net asset value (NAV) of its shares. NAV per share is determined by dividing
the value of the trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of common shares outstanding, while market
price reflects the supply and demand for the shares. As a result, the two
returns can differ significantly. On an NAV basis, the trust performed
relatively in line with its benchmark, the Lehman Brothers Municipal Bond Index,
but underperformed on a market-price basis. (See table below.)

The trust uses leverage to enhance its dividend to common shareholders. The
trust borrows money at short-term rates through the issuance of preferred
shares. The proceeds are typically reinvested in longer-term securities, taking
advantage of the difference between short- and longer-term rates. As yields rose
during the period, the prices of bonds declined. The trust's use of leverage
magnified this negative price movement. However, the portfolio saw strong
relative performance from its higher-yielding holdings during the period, which
counterbalanced the effects of leverage and helped to produce a total return at
NAV similar to that of the benchmark, which is not leveraged.

Our analysis of the macroeconomic environment, coupled with the levels of
interest rates near multi-decade lows, led us to believe that interest rates
were more likely to rise than to fall further. As a result, we kept the trust's
duration (a measure of interest-rate sensitivity) below that of its benchmark in
order to limit the potentially damaging impact of any increase in interest
rates. This approach hampered the trust's returns as interest rates fell for
much of the period. That said, the strategy helped cushion returns in the final
weeks of the period when interest rates soared.

additional performance information and index definition.

                                                                               3


We also adjusted the portfolio's term structure in anticipation of rising
interest rates. Our research showed that the intermediate portion of the curve
offered the most promising total-return potential. As a result, we focused our
purchases on the 15- to 20-year segment of the curve. These securities had the
added appeal of premium coupons and 10-year call dates, which offered attractive
income coupled with limited interest-rate exposure. Our term-structure strategy
also included an attempt to capitalize on a temporary pricing anomaly which
boosted the short-term returns of securities in the ten-year range as they
"rolled down" the yield curve at the end of the calendar year.

While the trust has a high-quality bias overall, its performance benefited from
its holdings of high-yield issues. During the period, municipal-bond investors
responded to the protracted low-rate environment by favoring high-yield bonds,
which caused the yield spreads between higher- and lower-rated bonds to narrow.
(Yield spreads reflect the premium demanded by investors to buy lower-rated
bonds.) As a result, lower-quality bonds outperformed. The portfolio had
approximately 83 percent exposure to bonds rated AA/Aa or higher at the end of
the period.

Our trading activity during the period was below traditional norms because we
wanted to avoid having to reinvest into securities with low yields. That said,
we were able to make selective relative-value trades among securities and
sectors as they moved into and out of fair value. Some of these acquisitions
were funded by the proceeds of bonds that were called away by their issuers
during the period. In other cases, we sold bonds that met their performance
objectives. We reinvested this cash into securities that we believed had more
promising total-return characteristics, including high-grade premium bonds, a
BBB/Baa-rated state-backed California issue, and an A/A-rated health-care
security.

The trust's portfolio remained well diversified during the period, with its
holdings spread across most major municipal-bond sectors. We believe this
long-standing strategy helps to minimize the risk of over-concentration in any
single sector, while also giving the portfolio exposure to as many potential
sources of return as possible. The three largest sector exposures at the end of
the period were general purpose, health care and public education.

As mentioned above, the portfolio's below-market duration served it well in the
final weeks of the period, when interest rates rose sharply. While it is
impossible to predict how long this trend will hold, we believe that the trust
is well positioned to weather further increases in rates. We look forward to
becoming more active in seeking attractive structures and relative-value trading
opportunities now that rates have moved into a more normal range.

(a)  As required, effective November 1, 2001, the Trust has adopted the
     provisions of the AICPA Audit and Accounting Guide for Investment Companies
     and began accreting market discount on fixed income securities. The effect
     of this change for the period ended October 31, 2002 was to increase net
     investment income per share by $.01, decrease net realized and unrealized
     gains and losses per share by $.01 and increase the ratio of net investment
     income to average net assets applicable to common shares by .03%. Per
     share, ratios and supplemental data for the periods prior to October 31,
     2002 have not been restated to reflect this change in presentation.

(b)  Total return assumes an investment at the common share market price at the
     beginning of the period indicated, reinvestment of all distributions for
     the period in accordance with the Trust's dividend reinvestment plan, and
     sale of all shares at the closing common share market price at the end of
     the period indicated.

(c)  Ratios do not reflect the effect of dividend payments to preferred
     shareholders.

(d)  Ratios reflect the effect of dividend payments to preferred shareholders.

(e)  Calculated by subtracting the Trust's total liabilities (not including the
     preferred shares) from the Trust's total assets and dividing this by the
     number of preferred shares outstanding.

VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST II

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2004 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Municipal Opportunity Trust II (the "Trust") is registered as a
diversified, closed-end management investment company under the Investment
Company Act of 1940 (the "1940 Act"), as amended. The Trust's investment
objective is to provide a high level of current income exempt from federal
income tax, consistent with preservation of capital. The Trust intends to invest
substantially all of its assets in municipal securities rated investment grade
at the time of investment. The Trust commenced investment operations on June 25,
1993. Effective November 30, 2003, the Trust's investment adviser, Van Kampen
Investment Advisory Corp. merged into its affiliate, Van Kampen Asset
Management.

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Trust may purchase and sell securities on a "when-issued" or "delayed delivery"
basis with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Trust will
segregate assets with the custodian having an aggregate value at least equal to
the amount of the when-issued or delayed delivery purchase commitments until
payment is made. At April 30, 2004, the Trust had $2,992,073 of when-issued and
delayed delivery purchase commitments.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security.

D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    The Trust intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At October 31, 2003, the Trust had an accumulated capital loss
carryforward for tax purposes of $1,415,668, which will expire

E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly
dividends from net investment income to common shareholders. Net realized gains,
if any, are distributed annually on a pro rata basis to common and preferred
shareholders. Distributions from net realized gains for book purposes may
include short-term capital gains and a portion of futures gains, which are
included as ordinary income for tax purposes.

    The tax character of distributions paid during the year ended October 31,
2003 was as follows:

<Table>

    Net realized gains and losses may differ for financial reporting and tax
purposes as a result of deferral of losses resulting from wash sales
transactions.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Asset
Management (the "Adviser") provides investment advice and facilities to the
Trust for an annual fee payable monthly of .60% of the average daily net assets
of the Trust. In addition, the Trust pays a monthly administrative fee to Van
Kampen Investments Inc. or its affiliates (collectively "Van Kampen"), the
Trust's Administrator, at an annual rate of .05% of the average daily net assets
of the Trust. Effective June 1, 2004, the administrative fee was reduced from
..05% to .00%.

    For the six months ended April 30, 2004, the Trust recognized expenses of
approximately $8,600 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Trust, of which a trustee of the Trust
is an affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Trust. The Adviser
allocates the cost of such services to each trust. For the six months ended
April 30, 2004, the Trust recognized expenses of

                                                                              19


VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST II

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2004 (UNAUDITED) continued

approximately $17,300 representing Van Kampen's cost of providing accounting and
legal services to the Trust, which are reported as part of "Other" and "Legal"
expenses, respectively, in the Statement of Operations.

    Certain officers and trustees of the Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
officers of Van Kampen.

    The Trust has implemented deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable upon retirement for a
ten-year period and are based upon each trustee's years of service to the Trust.
The maximum annual benefit per trustee under the plan is $2,500.

    At April 30, 2004, Van Kampen owned 6,700 common shares of the Trust.

3. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $20,791,012 and $16,531,048,
respectively.

4. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    In order to seek to manage the interest rate exposure of the Trust's
portfolio in a changing interest rate environment, the Trust may purchase or
sell financial futures contracts or engage in transactions involving interest
rate swaps, caps, floors or collars. The Trust expects to enter into these
transactions primarily as a hedge against anticipated interest rate or
fixed-income market changes, for duration management or for risk management
purposes, but may also enter into these transactions to generate additional
income. All of the Trust's portfolio holdings, including derivative instruments,
are marked to market each day with the change in value reflected in the
unrealized appreciation/depreciation. Upon disposition, a realized gain or loss
is recognized accordingly, except when exercising a call option contract or
taking delivery of a security underlying a futures contract. In this instance,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract.

    During the period, the Trust invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Trust
generally invests in exchange traded futures on U.S. Treasury Bonds and Notes
and typically closes the contract prior to delivery date. These contracts are
generally used to manage the Trust's effective maturity and duration. Upon
entering into futures contracts, the Trust maintains an amount of cash or liquid
securities with a value equal to a percentage of the contract amount with either
a future commission merchant pursuant to rules and regulations promulgated under
the 1940 Act, as amended, or with its custodian in an account in the broker's
name. This amount is known as initial margin. During the period the futures
contract is open, payments are received from or made to the broker based upon
changes in the value of the contract (the variation margin). The risk of loss
associated with a futures contract is in excess of the variation margin
reflected on the Statement of Assets and Liabilities.

5. PREFERRED SHARES

As of April 30, 2004, the Trust has outstanding 4,600 Auction Preferred Shares
("APS") in three series. Series A and B each contain 1,600 shares while Series C
contains 1,400 shares. Dividends are cumulative and the dividend rates are
generally reset every 7 days through an auction process. The average rate in
effect on April 30, 2004 was 1.065%. During the six months ended April 30, 2004,
the rates ranged from 0.500% to 1.450%.

    The Trust pays annual fees equivalent to .25% of the preferred share
liquidation value for the remarketing efforts associated with the preferred
auctions. These fees are included as a component of "Preferred Share
Maintenance" expense in the Statement of Operations.

    The APS are redeemable at the option of the Trust in whole or in part at the
liquidation value of $25,000 per share plus accumulated and unpaid dividends.
The Trust is subject to certain asset coverage tests and the APS are subject to
mandatory redemption if the tests are not met.

                                                                              21


VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST II

DIVIDEND REINVESTMENT PLAN

    The Trust offers a dividend reinvestment plan (the "Plan") pursuant to which
Common Shareholders may elect to have dividends and capital gains distributions
reinvested in Common Shares of the Trust. The Trust declares dividends out of
net investment income, and will distribute annually net realized capital gains,
if any. Common Shareholders may join or withdraw from the Plan at any time.

    If you decide to participate in the Plan, State Street Bank and Trust
Company, as your Plan Agent, will automatically invest your dividends and
capital gains distributions in Common Shares of the Trust for your account.

HOW TO PARTICIPATE

    If you wish to participate and your shares are held in your own name, call
1-800-341-2929 for more information and a Plan brochure. If your shares are held
in the name of a brokerage firm, bank, or other nominee, you should contact your
nominee to see if it would participate in the Plan on your behalf. If you wish
to participate in the Plan, but your brokerage firm, bank or nominee is unable
to participate on your behalf, you should request that your shares be
re-registered in your own name which will enable your participation in the Plan.

HOW THE PLAN WORKS

    Participants in the Plan will receive the equivalent in Common Shares valued
on the valuation date, generally at the lower of market price or net asset
value, except as specified below. The valuation date will be the dividend or
distribution payment date or, if that date is not a trading day on the national
securities exchange or market system on which the Common Shares are listed for
trading, the next preceding trading day. If the market price per Common Share on
the valuation date equals or exceeds net asset value per Common Share on that
date, the Trust will issue new Common Shares to participants valued at the
higher of net asset value or 95% of the market price on the valuation date. In
the foregoing situation, the Trust will not issue Common Shares under the Plan
below net asset value. If net asset value per Common Share on the valuation date
exceeds the market price per Common Share on that date, or if the Board of
Trustees should declare a dividend or capital gains distribution payable to the
Common Shareholders only in cash, participants in the Plan will be deemed to
have elected to receive Common Shares from the Trust valued at the market price
on that date. Accordingly, in this circumstance, the Plan Agent will, as agent
for the participants, buy the Trust's Common Shares in the open market for the
participants' accounts on or shortly after the payment date. If, before the Plan
Agent has completed its purchases, the market price exceeds the net asset value
per share of the Common Shares, the average per share purchase price paid by the
Plan Agent may exceed the net asset value

 22


VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST II

DIVIDEND REINVESTMENT PLAN continued

of the Trust's Common Shares, resulting in the acquisition of fewer Common
Shares than if the dividend or distribution had been paid in Common Shares
issued by the Trust. All reinvestments are in full and fractional Common Shares
and are carried to three decimal places.

    Experience under the Plan may indicate that changes are desirable.
Accordingly, the Trust reserves the right to amend or terminate the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
changes sent to all Common Shareholders of the Trust at least 90 days before the
record date for the dividend or distribution. The Plan also may be amended or
terminated by the Plan Agent by at least 90 days written notice to all Common
Shareholders of the Trust.

COSTS OF THE PLAN

    The Plan Agent's fees for the handling of the reinvestment of dividends and
distributions will be paid by the Trust. However, each participant will pay a
pro rata share of brokerage commissions incurred with respect to the Plan
Agent's open market purchases in connection with the reinvestment of dividends
and distributions. No other charges will be made to participants for reinvesting
dividends or capital gains distributions, except for certain brokerage
commissions, as described above.

TAX IMPLICATIONS

    You will receive tax information annually for your personal records and to
help you prepare your federal income tax return. The automatic reinvestment of
dividends and capital gains distributions does not relieve you of any income tax
which may be payable on dividends or distributions.

RIGHT TO WITHDRAW

    Plan participants may withdraw at any time by calling 1-800-341-2929 or by
writing State Street Bank and Trust Company, P.O. Box 8200, Boston, MA
02266-8200. If you withdraw, you will receive, without charge, a share
certificate issued in your name for all full Common Shares credited to your
account under the Plan and a cash payment will be made for any fractional Common
Share credited to your account under the Plan. You may again elect to
participate in the Plan at any time by calling 1-800-341-2929 or writing to the
Trust at:
