Our season runs Memorial Day weekend through Labor Day each year. Search our website any time to check out rates, view the facility rules, and peruse program offerings.

Attractions

The Collinsville Aqua Park is home to 7 slides, Monsoon Mountain, lazy river, leisure pool, lap pool and Aqua Climb Wall. At Collinsville Aqua Park you'll never pay for parking, all our inner tubes are free, and you'll never be charged to use any of our life jackets.

Lazy River

Take time out to relax and float in our lazy river. This figure-eight patterned pool is 3 and a half feet deep and is perfect for lounging in our free-to-use inner tubes. You can float solo or double up with our tandem tubes and let the currents carry you along.

Leisure Pool

The Leisure pool is the Aqua Park’s largest pool and features zero depth entry. The deepest end measures 4 and a half feet and comes complete with wide array of activities. There are two slides, one open-air and one tube, which are 3 stories tall and cover 170 feet emptying into the deepest end of the pool. Next, the lily pads float in the pool and, using the overhead rope, the adventurous can see if they can make it across. On the opposite end, across the water-spout walk-way, you'll find the Water Fortress play area where you can jostle valves, shoot water streams, and take a small 9 foot tube slide down into 2 feet of water. This area offers something for everyone visiting the park.

Monsoon Mountain

Monsoon Mountain is a 50 foot tall water castle of fun. It includes five slides of various shapes and sizes, and different hoses and buckets that kids can use to squirt each other with water. The bucket on top holds 500 gallons of water and douses the kids or unsuspecting parents below with its contents every five minutes. Two slides at the top of Monsoon Mountain, one open and one tube, have a 40 inch height requirement.

Lap Pool

The lap pool is a 4 lane pool with a maximum depth of 9 feet. It features stair-entry and contains an AquaClimb wall, a 12-foot-tall climbing wall situated above the deep end. Those craving a bit of adventure can climb the wall and jump into the deep water.
