About this activity

There is something wonderful about indoor waterparks. Do you know what that is? Well, it's the fact that no matter what the weather, you will still be able to have a great time there!

Grand Harbor Resort & Waterpark is one of Iowa's most popular water parks, with 25,000 square feet of water park fun for the whole family. There are a HOST of great water attractions for you to enjoy.

Those who love water slides will be in their element, and tube rides are always great fun for the whole family to enjoy.

Active kids will love playing, climbing and splashing around on the rope ladders are water chuttes, and there are even fun squirt guns and water cannons for the kids to play with.

Fancy just sitting back and taking it all in? That's what the Lazy River was designed to do! Don't forget about the fun activity pools which can keep the kids entertained for hours, as well as the two giant hot tub whirlpools. They are just as fun as they sound!

Did we mention the four story splash? No? Oh....that old thing. That's JUST 350 GALLONS of water that is dumped every 8 minutes from their four-story Huck Finn II Treehouse! Sounds amazing - but just you wait until you get caught underneath it!

The Watersquirts Kids Club is a center for all of the fun family activities too, that occur at the Garnd Harbor Resort & Waterpark.

Don't even think about what to do on your family day out - just dive right in!
