An Indiana Water Park featuring a lazy river, waterslides, wave pool and more!

Residents and visitors alike love the Splash House water park, one of the best, family-friendly water parks in Indiana. The Splash House opens for the 2017 season on May 27! Visitors can beat the heat of the summer sun at Junction Park in the heart of Marion, Indiana. Grab an inner tube, drift down the lazy river ride, cool down and enjoy a tranquil moment.  For exhilarating high speed fun, two wild, looping, twisty water slides hurtle you to the ultimate splashdown.  Or frolic in the kids’ play zone. This exciting area offers fountains, and splashes and sprays for kids of all ages. Jump in to the wave pool and crash into the rolling waves that feel like the ocean. Visitors to Splash House water park can even work on that perfect tan on more than 30,000 feet of deck space.

The Indiana water park is conveniently located in Marion, Indiana, a short drive from Gas City, Kokomo, Muncie, and all of East Central Indiana. Marion’s Junction Park Splash House provides something fun to do for all ages!

The Splash House opens rain or shine if the temperature is above 65 degrees Fahrenheit.  The Splash House is, however, subject to closure due to unforeseen circumstances, such as dangerous weather, low attendance, maximum facility capacity, or maintenance.  Please call ahead (765-668-1794)  or visit our Facebook page to avoid disappointment.
