WaTiki® Indoor Waterpark Resort

WaTiki® Indoor Waterpark Resort has more than 30,000 square feet of slides, pools and a lazy river under one roof. Its three large waterslides, including tube slides and the Seahorse body slide, all connect to the lazy river. An activity pool has lily pads and basketball hoops, Koko's Kingdom gives younger kids mini slides and a giant dumping bucket, and the Oasis hot tub offers a quieter spot after a busy day.

The waterpark is open year-round and sits alongside five connected hotels, on-site dining and a large arcade. Guests who book a stay at a participating hotel get waterpark access included. The resort also hosts birthday parties and group getaways. It is located on North Elk Vale Road in Rapid City, South Dakota.
