Alaska is known for the majestic outdoor beauty of Mount McKinley, its vast lands of forest, and abundant wildlife. Indoors, Alaska is also home to one of the largest enclosed water parks in the United States. H2Oasis, on a three-acre site in Anchorage, has proven to be a paradise in the midst of the arctic tundra for people to escape into a tropical destination without spending a bundle. This tropical indoor water park has the capacity to hold over 1,000 occupants in the 55-ft high building, encompassing 40,000 sq ft in south Anchorage.
