World's Largest Interactive Waterplay Structure to
Anchor New Six Flags Hurricane Harbor

GURNEE, ILLINOIS— Say "bon voyage" to the outside world! Six Flags officials have
announced plans to build a massive new water park on a site next to Six Flags Great
America, in Gurnee, IL. Carrying the Six Flags Hurricane Harbor brand name, details of
this 13-acre, outdoor water park include a lavish Caribbean theme with more than 25
major water slides, the world's largest interactive waterplay structure and a 500,000
gallon wave pool.

"The Six Flags Hurricane Harbor brand is well known in the theme park industry for top
quality water attractions that deliver a whole day of fun," said Hue Eichelberger,
executive vice president, Six Flags, Inc. "This new Six Flags Hurricane Harbor water
park will live up to its brand name by featuring some of the most exhilarating water thrills
on the planet."

As guests enter the new Six Flags Hurricane Harbor water park, it will feel as if they
have just stepped off a vacation cruise ship onto a private Caribbean island. This "shore
excursion" will provide Six Flags Hurricane Harbor guests with a vacation-full of water
attractions for the whole family. Island music and lush landscapes will provide the
backdrop to a fabulous collection of water slides, erupting water geysers, rafting
options, waterfalls, beach areas and lazy hideaways.

"This new water park will give guests the opportunity to vacation close to home," said
Tim Black, vice president and general manager of Six Flags Great America and Six
Flags Hurricane Harbor. "You don't have to travel to the Caribbean islands to

experience all of its exciting thrills. Six Flags Hurricane Harbor will offer the ultimate
family escape and a full day of Caribbean fun."

At the porthole to this tropical get-away is the exciting adventure river where guests can
float down a relaxing river through waterfalls and rich landscaping while circling a large
portion of the new water park. A gigantic, half a million-gallon wave pool will produce
ocean-like waves every few minutes and dozens of water slides will tower above the
park offering a variety of high-speed thrills.

Anchoring Six Flags Hurricane Harbor will be the world's largest interactive waterplay
structure, Skull Island, complete with seventeen towers connected by swinging bridges
and net climbs, intertwining children's slides and hundreds of water gadgets, jet
sprayers, water blasters and more! Connected to an additional 23,000 square-foot
activity pool geared for the park's younger guests, this area provides countless play
opportunities for families.

"The sheer size of this waterplay structure is unlike anything else in the world," said
Black. "Six Flags is known for building the biggest and best for our guests and our new
water park is no exception."

"This world-class, water park complements all the family fun and thrills of its sister
theme park, Six Flags Great America" Black continued. "With an entertainment complex
of this magnitude, guests will need multiple days to experience all the excitement Six
Flags has to offer."

Six Flags Hurricane Harbor will have its own entrance plaza and admission, separate
from the theme park. Ticket information, operating hours and season pass information
will be available soon by visiting
