The Reef

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.
