Kalahari Resorts plans $76m indoor waterpark expansion in Wisconsin Dells

Kalahari Resorts & Conventions, already celebrated for hosting America’s largest indoor waterparks, has announced a landmark $76 million expansion at its flagship Wisconsin Dells resort. This ambitious project will add a 75,000-square-foot, glass-enclosed waterpark with a retractable roof, solidifying the resort’s position as a premier destination for family entertainment. Slated for completion in fall 2026, the new waterpark will elevate the guest experience with state-of-the-art slides, pools, and luxury amenities.

A Game-Changer for Wisconsin Dells Tourism

Wisconsin Dells, often referred to as the “Waterpark Capital of the World,” will gain another attraction through this development, attracting visitors from across the United States. The expansion aligns with Kalahari Resorts’ mission to create spaces where families can bond and make lasting memories. The planned waterpark’s innovative design ensures year-round operation, regardless of Wisconsin’s weather conditions.

Todd Nelson, the CEO and founder of Kalahari Resorts, emphasized that this development is not just about growth but about creating unparalleled experiences. He attributed the resort’s long-standing success to the concept of Ubuntu, an African philosophy of togetherness that has inspired the brand since its inception.

“Kalahari is more than just a waterpark,” Nelson explained. “It’s a place for families to connect and celebrate life’s moments. This expansion allows us to welcome even more guests into an environment built on the principles of unity and joy.”

What Guests Can Expect from the Expansion

The expanded indoor waterpark will introduce several cutting-edge attractions, offering thrills and relaxation for visitors of all ages. Among the new features are three water slides designed to deliver unique experiences:

Wild Wildebeest and Green Python: These six-person raft slides offer high-energy rides with twists and turns.

Cheetah Mat Racers: A four-lane racing slide for competitive fun.

Additional amenities include the Lost Lagoon Spa Pool, the Watering Hole Pool with zero-depth entry and tanning ledges, the Coral Cove Kiddie Slide Pool, and The Grotto, an adult-only swim-up bar. Families and groups will also appreciate enhanced seating options, including luxury cabanas and whirlpool cabanas.

The entertainment doesn’t stop at the water attractions. A massive 40-foot-wide big-screen TV display will add to the ambiance, creating opportunities for group viewing experiences. The resort will also expand its food and beverage offerings to cater to diverse tastes, ensuring guests have access to premium dining and refreshments.

Continued Commitment to Excellence

This expansion is part of Kalahari Resorts’ broader effort to provide exceptional experiences across its properties. Recent upgrades at the Wisconsin Dells location include 237 newly constructed guest rooms, a revamped Spa Kalahari, an upgraded lobby, a splash pad and dry playground for children, and two new restaurants: Sortino’s Italian Kitchen and Cinco Niños, a modern Mexican eatery featuring a tequila bar.

As a privately owned brand, Kalahari Resorts is deeply rooted in the values of its founders, Todd and Shari Nelson. Both Wisconsin natives, the Nelsons were inducted into the Wisconsin Business Hall of Fame in 2023 for their contributions to local tourism and the state’s economy. Their passion for innovation and hospitality has propelled the brand to national prominence, with locations in Sandusky, Ohio; the Pocono Mountains, Pennsylvania; and Round Rock, Texas. A new property is also under construction in Spotsylvania County, Virginia.

Economic and Tourism Impact

The expansion is expected to boost local tourism significantly, drawing more visitors to Wisconsin Dells and providing economic benefits to the region. By continually reinvesting in its properties, Kalahari Resorts has maintained its reputation as a leader in family-friendly entertainment.

Industry analysts highlight the significance of Kalahari’s investment strategy. By prioritizing guest experience and staying ahead of trends in entertainment, the brand has positioned itself as a top choice for both leisure and corporate travel. The state-of-the-art convention center at each location complements its waterparks, attracting conferences and events that further contribute to economic growth.

The Vision Behind Kalahari Resorts

The roots of Kalahari Resorts trace back to a family trip to Africa, where Todd Nelson was inspired by the idea of Ubuntu. This vision has influenced every aspect of the brand, from its African-themed decor to its focus on creating shared experiences for families.

Since opening its first resort in Wisconsin Dells in 2000, Kalahari has expanded into a national brand while maintaining its commitment to its core values. The latest waterpark addition underscores the company’s dedication to continuous improvement, ensuring that guests have access to the latest in entertainment and comfort.

Looking Ahead to 2026

With the fall 2026 completion date, anticipation for the new indoor waterpark is already building. Families planning vacations to Wisconsin Dells can look forward to a destination that offers something for everyone, from adrenaline-pumping slides to tranquil spa pools.

Kalahari Resorts’ $76 million investment signals more than just an expansion—it’s a commitment to innovation, community, and family-focused entertainment. As Wisconsin Dells continues to evolve, Kalahari remains a cornerstone of its vibrant tourism landscape.
