Largest Indoor Water Park In Montana!

The Reef Indoor Water Park is the largest indoor water park in the state of Montana – it’s as big as a football field! Climb 3 stories up, then rocket down the Barracuda Blaster or the Tropical Twister – guaranteed to charge your batteries! – then shoot into the plunge pool when you emerge from the tubes. If you’re game, challenge your friends to a round of water basketball – guaranteed to separate the movers from the sitters. Need a break? Ride 3-foot waves in the 55,000 gallon wave pool, or really relax in our 25-person hot tub where the water is always a soothing 103 degrees.

The little guys have the greatest interactive playhouse designed just for them – slides, mini-tubes, squirt guns, and tunnels – and best of all, a 250-gallon dumping bucket! Safe, fun, and tough enough for Mom and Dad – even Grampa!

Tables surround The Reef, indoors and outside on the enclosed patio – space everywhere for families to gather – and when you all get hungry, Ripp’s Café has something for everyone! Ripp’s is catered by the renowned chef and staff at the Big Horn Resort – pizza to die for, homemade mac and cheese, and much much more!

We look forward to serving you at The Reef!
