Kalahari Resorts Wisconsin Dells pairs a 125,000-square-foot indoor water park with African-themed decor, a seasonal outdoor park, and a nearly 800-room resort — making it one of the anchor reasons Wisconsin Dells calls itself the Waterpark Capital of the World. It opened May 4, 2000, as the vision of Wisconsin Dells natives Todd and Shari Nelson, who named the property after the Kalahari Desert following a family trip to southern Africa.
Beyond the history, most people searching for Kalahari want practical answers: what time the water park opens, whether non-guests can buy tickets, how much a day pass costs, and where to park. This guide covers both — the resort’s record-setting attractions and the details you need to actually plan a visit.
Quick Answer
The indoor water park at Kalahari Resorts Wisconsin Dells is open daily, generally 10 a.m. to 9 p.m., and the seasonal outdoor park runs 10 a.m. to 7 p.m. from Memorial Day through Labor Day, weather permitting. Overnight resort guests get water park access included with their stay; non-guests can buy separate day passes online, with prices that shift by day of the week, season, and demand rather than a single fixed rate.
A 75,000-square-foot, $85 million indoor expansion — adding a retractable glass roof, new raft slides, and adult-focused areas — is under construction and expected to open in Fall 2026.
Water Park Hours
The 125,000-square-foot indoor water park operates year-round, typically from 10 a.m. to 9 p.m. daily. The 77,000-square-foot outdoor water park is seasonal, generally open 10 a.m. to 7 p.m. from Memorial Day through Labor Day, and it closes for the day if weather (lightning, in particular) makes it unsafe.
Hours can shift around holidays, peak-season crowd levels, or off-season maintenance closures for specific slides. Overnight guests can typically use the indoor water park starting the morning of check-in day through closing time on check-out day. Because hours are subject to change, check the official Kalahari Wisconsin Dells hours guide before you go.
Tickets, Day Passes & Pricing
Overnight guests staying at the resort get water park access included with their room. Non-guests can still get in: Kalahari sells a limited number of waterpark day passes online each day, and once a day sells out, no more passes are released for that date — so booking ahead matters, especially on weekends and holidays.
Pricing is dynamic rather than a single flat rate — expect a noticeably higher price on weekends and holidays than on a quiet weekday, plus options like all-day passes, evening-only passes at a discount, combo passes that bundle Tom Foolerys Adventure Park, multi-pass bulk discounts for groups, and a discounted rate for military ID holders. Day passes are non-refundable once purchased online, and pass holders should bring their own towels since they aren’t provided. For current prices and available dates, use the official waterpark day pass page, which is the only source that reflects real-time pricing and sellout status.
Getting There, Parking & the Resort Fee
Kalahari Resorts Wisconsin Dells is located at 1305 Kalahari Drive, Wisconsin Dells, WI 53965. The resort notes that GPS and MapQuest sometimes route more accurately if you enter the city of Baraboo rather than Wisconsin Dells directly, so double-check your route if a map app seems off.
Self-parking is free for guests — there’s no separate parking fee and no valet option. Overnight stays do carry a daily resort fee (charged per room, plus tax) that covers self-parking, in-room safe use, high-speed Wi-Fi, fitness center access, life jacket use in the water parks, and daily family activities. That fee is separate from water park day passes, which are priced and sold on their own. Because resort fee amounts change periodically, confirm the current rate on the official resort fee page.
Signature Attractions
The indoor park’s centerpiece is the Master Blaster, a 570-foot uphill water coaster that uses jets of water to push riders up and down hills — giving it the feel of a roller coaster without leaving the water. It was the first attraction of its kind installed indoors anywhere in the country.
Victoria Falls, a 504-foot family raft ride, and a 920-foot indoor lazy river round out the park’s headliners. The FlowRider surfing simulator — also a national indoor first — fires roughly 50,000 gallons of water per minute to produce a continuous wave for beginners and experienced surfers alike.
The seasonal outdoor water park adds rides including the Anaconda, Extreme Rush, and the Smoke that Thunders, giving warm-weather visitors an additional set of thrills beyond the indoor park.
Safety Rules & Bag Policy
All bags are subject to being checked at entry, and outside coolers, food, and beverages aren’t permitted in the water parks (exceptions are made for baby food, formula, breastmilk, and allergy-related snacks). Weapons, glass containers, and illicit substances are prohibited.
U.S. Coast Guard-approved life jackets are required for anyone under 48 inches tall and for non-swimmers; complimentary jackets are available on a first-come, first-served basis and are covered by the resort fee. The FlowRider has its own height minimums — around 42 inches to bodyboard and 52 inches to stand up — and children under 14 need adult supervision, with kids under 5 required to stay within arm’s reach of a supervising adult.
Growth and Expansion
Kalahari opened in 2000 with 74,000 square feet of indoor water park. A December 2002 expansion brought it to 125,000 square feet and briefly made it America’s largest indoor water park, a title it held until its Sandusky, Ohio sister resort surpassed it in 2007. A 2011 renovation added what was then the nation’s first indoor Super Loop slides.
In January 2025, Kalahari announced an $85 million, 75,000-square-foot indoor expansion, now under construction and slated to open in Fall 2026. The glass-enclosed addition will feature a retractable roof (engineered by OpenAire) for open-air access in warm weather, new WhiteWater-designed raft slides including the Wild Wildebeest, Green Python, and the four-lane Cheetah Mat Racers, plus a zero-depth-entry area called the Watering Hole, a family zone called Adventure Bay, and adult-focused spaces including The Grotto swim-up bar and the Lost Lagoon spa whirlpool.
