Great Wolf Lodge’s indoor water park resorts are notable for their scale and the number of locations. As of early 2023, there are 20 parks, including one in Canada. The parks vary in size, with the largest (in Anaheim) clocking in at more than 100,000 square feet. Regardless of location, expect to splash around across lazy rivers, wave pools and waterslides in winter-friendly pools heated to 80-plus degrees. There are also usually some activities on dry land, too, such as arcade games and bowling. With accommodations on-site in woodsy suites, you can easily make visiting a Great Wolf Lodge location into an overnight trip.
