Just about 90 minutes from downtown Chicago, Grizzly Jack's is ideal for a weekend family getaway. At the 24,000 square foot indoor waterpark, you can splash in the wave pool, slide down a water slide, float down the lazy river, or wade in the kiddie pool with your little ones. Other activities include the Cave Arcade, park train, and The Enchanted Forest, a 36,000 sq. foot indoor amusement park.
