The heart and soul of Great Wolf - Lodge Boston/Fitchburg is its 68,000-square-foot indoor water park. Splashy rides such as the Howlin’ Tornado—an enclosed water slide that shoots you through a six-story funnel—and a zero-depth-entry wave pool with 3-foot swells surround the park’s iconic hub: a four-story treehouse with a huge tipping bucket. Younger kids will have a blast with the water slides and gentle spray features of Whooping Hollow and Cub Paw Pool.

The water park, which hovers around 84 degrees all year long, isn’t the resort’s only family-friendly activity. You’ll also find mini bowling at Ten Paw Alley, and Howl at the Moon mini golf.
