Splash Island Water Park in Plainfield is a West Side Secret

Nothing says summer quite like a pool day at the public pool, or better yet, a waterpark day! Enter Splash Island Water Park in Plainfield.

I’m so thankful that the Indianapolis area is home to some pretty spectacular pools, water parks, and splash pads. The best part? Other than proximity and variety, the price for admission is a pretty good deal!

Splash Island Water Park in Plainfield will open for the 2024 season with a Member’s Only Preview Night on May 22. The Waterpark will open to the public on May 24 and will close for the summer on Labor Day Monday.

New and Improved for the 2024 Season

Last fall, Plainfield announced extensive additions and renovations at Splash Island. The new developments include three waterslides, which will give the park a grand total of six. You can also expect to see a splash pad, cabanas for rent, an updated maintenance building, and a new play structure to replace the one previously located in the main pool.

These exciting attractions are on course to open with the rest of the waterpark at the beginning of the 2024 season.

Play and Relax at Splash Island

Splash Island in Plainfield is a gorgeous and fun outdoor water park with so many different things to do. No matter what your speed is when you visit, Splash Island Water Park is a ton of tun.

Splash Island Water Park in Plainfield, Indiana

Splash Island has a lazy river, but they named it a “Leisure River” and I’m okay with that! This is my favorite feature at any water park and the Splash Island Waterpark river is one and a half times the length of the river at the Carmel Waterpark. This means I get to lay back and relax for a long time. Now that you all know where to find me, let’s talk about the other awesomeness that Splash Island Water Park has!

Splash Island Waterpark Water Slides

There are three water slides that are about 2 ½ stories tall and a six-lane competition pool with an attached diving well and two diving boards. My extreme adrenaline-loving kids love these areas.

Water Park Play Areas

There’s an interactive play area for all ages including kiddie slides, water jets, ropes, and water guns, a gently winding river. This is a river that’s separate from the Leisure River. My kids love the lily pad crossing, two pulsating vortexes, and the pool area for infants and small children, known as the GUPPY TANK.

I love that there’s plenty of deck space and grassy areas for sunbathing and family fun. There’s even a sand castle play area!

Food at the Plainfield Waterpark

There is a snack bar area that sells snacks and lunch items, including my favorite: Dippin Dots! You are allowed to bring your own lunch in a cooler but they are to be kept in a designated area and will be searched when you arrive. No glass and no commercially prepared food.
