Family Activities


Make a splash at Grand Harbor Resort’s onsite indoor waterpark! We offer 25,000 square feet of wet fun for the entire family – including 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!

    Cave Arcade

    Be sure to visit the “Cave”, our huge interactive game room, with all of your favorite video and arcade games, including the Wheel of Fortune, Whack-a-Mole, and Ski Ball. Collect tickets to redeem for prizes at our prize redemption center.
