                           SIX FLAGS, INC. (NYSE: PKS)
                               YEAR-TO-DATE UPDATE

         NEW YORK, July 18, 2001- Kieran E. Burke, Chairman and Chief Executive
Officer of Six Flags, Inc. ("Six Flags") (NYSE: PKS) commented today on Six
Flags' performance for the year-to-date period ended July 15, 2001

         "Through last weekend, our combined systemwide attendance is up
approximately 3.3% over same period last year. Combined with an aggregate per
capita spending increase of 2.0% in constant currencies, this attendance growth
has caused park-level revenues to be up 5.0% over last year on a constant
currency basis. (Constant currencies restate last year's international
performance at this year's rates.)

         "A portion of this revenue growth is attributable to the inclusion in
our results of the parks acquired since the close of our 2000 operating season.
Since the former Sea World of Ohio now operates together with Six Flags of Ohio
as a single gate, it is difficult to separate out this park's performance.
Excluding the results of Montreal and Seattle, revenues are up approximately
4.0% in constant currencies over the prior year.

         "Our early season performance was not as strong as we had originally
hoped. We were hampered by difficult early season weather in Europe and, to a
lesser extent, in some Northeastern markets. We have also experienced somewhat
lower than expected growth in per capita spending, particularly in Europe, which
may reflect the impact of difficult economic conditions.

                                     (more)

"We have seen a significantly improved performance trend over the past several
weeks. In addition, we have good season pass sales and solid group bookings.
With approximately 50% of our season remaining, it is difficult to predict with
certainty what our full year performance

will be, and whether these improved trends and good advance bookings will propel
a performance which will close the gap to our expected $460 million in Adjusted
EBITDA for the year. We will report further at the time of the release of our
second quarter figures in mid-August."

         Six Flags, Inc. is the world's largest regional theme park company,
with thirty-eight parks in markets throughout North America and Europe.
