Make a splash at Grand Harbor Resort’s onsite indoor waterpark! We offer 25,000 square feet of wet fun for the entire family. This refreshing experience includes waterslides, tube rides, rope ladders, waterspouts, water chutes, squirt guns and powerful water cannons as well as a lazy river, activity pools, and two giant hot tub whirlpools. Grab a snack at the River’s Edge Café or experience the “four story splash” – 350 gallons of water dumped every eight minutes from our four-story Huck Finn II Treehouse!
