Aquatopia at Camelback Resort in Tannersville is a big indoor water park that keeps everyone happy whatever the weather, about 25 to 35 minutes from Lake Harmony.
Ride the wave pool, float along the indoor/outdoor lazy river and race down the slides. There's something for every age, from toddler areas to bigger thrills for teens.
Aquatopia is open daily from 10 AM to 8 PM. Day passes are limited, so book online ahead of your visit, and call (570) 629-1665 with questions.
