The Grand Harbor Resort and Waterpark in Dubuque, IA is Iowa's first themed indoor water park resort. Step back in time to the days of Huckleberry Finn at this Mississippi-themed water adventure play land.

Run for cover when Huck Finn's whistle blows (every 9 minutes); a huge bucket will dump nearly 800 gallons of water on those who dare to get close!

You'll also experience thrilling waterslides, indoor/outdoor tube ride, rope ladders, lazy river, giant whirlpools, and a large interactive water play area with squirt guns, geysers, and water chutes.

No need to drive all the way to the Wisconsin Dells for an indoor water park adventure. The Grand Harbor Resort and Waterpark has fun and adventure for every member of your family!
