Indoor fun for everyone

Indoor Water Park

Make a Splash at H2Oooohh!

H20ooohh!! is an indoor family water park adjacent to the Galleria at Split Rock Resort in beautiful Lake Harmony, Pennsylvania. With 53,326 square feet of water attractions to enjoy, H20ooohh! has five exciting body, tube and raft slides, a wavepool, activity pool, fun play structure, crossing activity, snack and Tiki bar, and more.

Adventure seekers won’t get enough of our most popular features, like the Komodo Dragon – Pennsylvania’s First Indoor Flow Rider, the Viper, the Piranha, and the Amazon Blast slides that drop an incredible four stories! For water park goers looking for a more relaxing way to stay refreshed, try the Lava Springs hot tubs, while the little ones will have a great time at the Jungle Falls & Leapin' Lizards play areas.
