America’s Largest Indoor Waterpark is solidifying its title with a new $85 million expansion set to be completed next year. Kalahari Resorts waterpark will have a glass-enclosed retractable roof which will introduce three new water slides: the Wild Wildebeest, Green Python, both six-person raft slides, and the Cheetah Mat Racers, a four-lane racing slide. Some new attractions also include the Lost Lagoon Spa Pool, the Watering Hole Pool, the Coral Cove Kiddie Slide Pool, and The Grotto adult swim-up bar.
