Nothing is more exciting than spending a hot summer day cooling off in the largest indoor water park in the state of Montana. Reef Indoor Water Park is bigger than a football field and has rides and slides suitable for everyone in the family - from toddlers to grandparents.
Activities include an interactive playhouse with a 250-gallon water dumping bucket, a three-story tube slide, the Tropical Twister body slide, and a 55,000 gallon wave pool with waves over three feet high. Visitors can play a round of water basketball in the activity pool or unwind in the 20-person hot tub. Amenities include locker rooms, showing areas and bathrooms, as well as a first aid station and private party rooms and patio space that can be rented out.
