Kalahari Resorts just announced an $85 million indoor waterpark expansion that’s guaranteed to make every family trip unforgettable—whether you’re chasing thrills or just trying to keep your kids from cannonballing into the hot tub.
The Wisconsin Dells Is Making a Splash!

Get ready, waterpark warriors—Kalahari Resorts in Wisconsin Dells is diving into something BIG. How big? Try $85 million big. That’s right, the Midwest’s favorite vacation spot is adding a jaw-dropping 75,000-square-foot indoor waterpark expansion, and it’s making waves starting in fall 2026.
Thrills for the Whole Crew
This expansion is all about upping the fun. You’ll find three epic new water slides designed for maximum excitement. Test your bravery on Wild Wildebeest or Green Python, two gigantic 6-person raft slides, perfect for family bonding (or competitive screaming).

Parents, this isn’t just about adrenaline-pumping thrills. The expansion also features spaces where you can relax while the kids burn off their endless energy. Chill at the Lost Lagoon Spa Pool, kick back at the Grotto swim-up bar, or lounge poolside at the Watering Hole Pool with zero-depth entry and tanning ledges. Got toddlers? They’ll love the Coral Cove Kiddie Slide Pool.
