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. Need a break? Ride waves in the 55,000-gallon wave pool.

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 strong enough for Mom and Dad – even Grandpa! 

Tables surround The Reef, indoors and outside on the enclosed patio – plenty of space for families to gather – and when you all get hungry, Shark Shack has something for everyone!

We look forward to seeing you at The Reef!
