The Tundra Lodge Resort in Green Bay, WI, is the largest indoor water park in the area.

The 20,000 sq. ft. indoor water park features two 250 ft. water slides, a lazy river, an interactive water playground, a children's pool, an outdoor splash pad and whirlpool, and indoor hot tubs.

Seeming somewhat like a scaled-down version of the large resorts in the Wisconsin Dells, this resort is a nice alternative for a short weekend getaway or overnight excursion. You will find it to be not only less crowded, but also significantly less expensive.
