H2Oasis Indoor Waterpark

H2Oasis Indoor Waterpark is Alaska's only indoor water park — a 56,000-square-foot aquatic facility that maintains a tropical 84°F year-round, no matter how cold it gets outside. Located at the south end of Anchorage off O'Malley Road, the park sits about 20 minutes from downtown and welcomes families, school groups, and visitors looking for an indoor escape no other destination in Alaska can provide.

The centrepiece ride is the Master Blaster, a 42-foot water coaster that shoots riders uphill on jets of water before sending them back down. The Never Ending River provides a gentler option — a lazy float that loops the entire building. The Wave Pool generates rolling swells every few minutes, giving swimmers of all levels a surf-like experience. The Children's Lagoon offers a dedicated shallow-water zone with seven small slides and a playground structure built for smaller guests. The Sea Dragon Pirate Ship Playground anchors the facility's center with water cannons, dump buckets, and climbing nets.

H2Oasis also runs swim lessons and fitness classes, making it a genuine community resource alongside its tourist-attraction role. An on-site cafe serves pizza, burgers, hot dogs, and soft-serve ice cream. Group packages, birthday party rentals, and corporate events are available.

General admission runs approximately $24.99 for ages 3–12 and $29.99 for ages 13 and up. Children under 2 enter free with a paid adult. Annual passes and a military discount are available. The park is open on weekends; check the official website for current seasonal hours before visiting, as schedules vary.
