Outdoor Park Hours
Closed for the Season. See you in 2025!
Climbing Wall
Test your skills or compete against your friends on our 16 foot climbing wall that overhangs the water.
Teen Corner
Early teens don't need to be hanging out with their little siblings anymore! They have their own space complete with shade, charging stations, and a view from the best corner of the park.
Zero Depth Pool
Start 'em young! Here little ones can enjoy water features and a splash pad in water that only reaches 2.5ft in depth
Snack Shop
Nothing creates hunger like a few hours of water-induced burnt energy. All sorts of hot and cold treats including pizza, ice cream, candy, and drinks are available!
Aqua Zip Line
Hold on tight to the only aqua zip line in Iowa! Take off above the water starting from an 8-foot platform.
Indoor Park
When the weather isn't cooperating, there's still plenty to do inside. Take the plunge down two waterslides, navigate the water channel on floating lily pads, cross the shallow pool to reach the aqua playground, take a dive and a lap in the 25-meter swimming pool, or warm up in the hot tub with jets.
Water Slides
Take a ride down one of three slides: body, tube, or speed slide!
Lazy River
Enjoy a relaxing float around our 400-foot lazy river or hop on while the waves are in action for a bit more action.
Recreation Pool, Waterfall, and Mini Slides
For those not tall enough for the big slides but want more thrill than the zero depth pool, the recreation pool is perfect!
