Collinsville Aqua Park

Collinsville Aqua Park (formerly Splash City) is now under the operation of the City of Collinsville and its new Parks and Recreation Department as of 2019, it's 22nd season.

This family waterpark offers something for everyone when it comes to summer fun, including a variety of water attractions like the popular FlowRider, body boarding and surfing wave simulator. 36,000 gallons of water a minute are pumped to create the perfect never-ending wave.

Monsoon Mountain is a five-story water fortress with five slides of different sizes, interactive water features and giant 500-gallon bucket that douses all every five minutes. You'll also find two waterslides, one fully enclosed for your enjoyment.

The waterpark also has a four-lane lap pool with 12-foot climbing wall, figure-eight shaped lazy river, water activity pool with lily-pad walk, body slides and a toddler pool called Guppy Gully.

Collinsville Aqua Park has lockers for your belongings, plenty lounge and deck chairs for relaxing, umbrellas for shade, and a full concession area. The waterpark can also accommodate groups and private events in the morning and evening hours and offers birthday party packages. Parking, tubes, life jackets and surfboards are also free.
