Great Wolf Lodge Grand Mound

Centralia, Washington

Great Wolf Lodge's Bear Track Landing is one of America's largest indoor waterparks. This 56,000 square-foot waterpark has six water slides, three pools and a four-story treehouse water fort. The signature attraction, Howlin' Tornado, is the world's first enclosed multi-rider Tornado tube ride. Howlin' Tornado sends four riders in a cloverleaf tube down six-stories into a giant funnel lying on its side. Beaver Tail Lake is the park's 110,000 gallon indoor water pool.
