The 10 Best Indoor Water Parks for Your Winter Vacation

The Wisconsin Dells has long been known as the Waterpark Capital of the World, so it should come as no surprise that some of the world’s most innovative indoor waterparks are located here. Mt. Olympus Water & Theme Park Resort’s indoor waterpark made history in 2022 with Medusa’s Slidewheel Waterslide, the country’s first rotating slide. Part Ferris wheel, part thrilling raft slide, this massive spinning slide is unlike any water ride you’ve ever experienced. Hop on the four-person raft and prepare to enter the turbine for 96 seconds of completely disorienting thrills. Not for the light-hearted, you’ll be subjected to intense g-forces that alternate with weightlessness as you hover back and forth through the dizzying cylinder maze. Medusa is the main attraction here, though the rest of the indoor waterpark offers some delightful thrills with a lazy river, tube slide, and fast body slide. The park is only open from mid-September through mid-May, but Medusa is open year-round.

A quick two-hour drive from New York City and Philadelphia, Aquatopia Indoor Waterpark at the Camelback Resort is an excellent winter weekend retreat. The park has an impressive lineup of 13 waterslides, including two drop slides, North America’s longest uphill water coaster, and the one-of-a-kind Venus Slydetrap. The Venus flytrap-inspired raft ride is a giant, eye-catching centerpiece of the park and a must for thrill seekers. The vibrantly colorful, well-themed park is great for families, with plenty of less-thrilling splash areas for the younger set. Family favorites include The Lost River lazy river that floats through fun adventure scenes, the large wave pool, and the action-packed FlowRider surf simulator. The indoor water park is open year-round and is one of the many family-friendly activities at the sprawling Camelback Resort.

With four locations nationwide, Kalahari Resorts & Conventions is a collection of remarkably large indoor waterpark destinations. The company’s origins trace back to its first indoor waterpark in the Wisconsin Dells, a year-round oasis of fun featuring Master Blaster, the first indoor uphill water coaster. Since its big splash on the scene in 2000, the company now operates large-scale indoor waterparks in Sandusky, Ohio; Poconos, Pennsylvania; and Round Rock, Texas, with plans to add a fifth location in Spotsylvania County, Virginia, in 2026. These indoor waterparks are stunning in magnitude, all with theming inspired by African wildlife. Head to the Poconos’ location to experience the wild ride on the country’s first VR Waterslide. With the VR headset firmly on your head, you’ll set off on a coaster slide as a virtual world journeys with you. Each park has a unique layout with towering slides, lazy rivers, multiple play areas for kids, and swim-up bars for adults.

Set about 90 miles north of Detroit, Zehnder’s Splash Village Hotel & Waterpark is a Midwest indoor waterpark destination. After an impressive facelift and expansion in 2021, this regional favorite since 2005 is now one of the most beautiful indoor waterparks in the country. One of the park’s highlights is its massive retractable room, an architectural work of art. Float along the lazy river and take in the incredible sky views. The park’s thrills include a 360-degree loop drop slide (that’s the kind where the floor drops out below you, plunging you straight down!), a six-story family raft slide, and fast four-story tube slides in the dark. The park operates year-round.

The winters can be long and grey up north in Vermont, near the Canadian border. Luckily, there’s Pump House Indoor Waterpark, an idyllic winter retreat with water fun for the family. Encased by a beautiful glass dome atrium that fills the space with natural light, this park is intricately themed and well-maintained. Two tube slides, a body slide, and one harrowing drop slide (where the floor drops out beneath you!) are the main attractions here, with other highlights including the FlowRider surf simulator and an adventurous river float. Most unique is the park’s climbing wall off the side of the pool. Test your grip as you boulder, knowing that the pool splash is there to break your fall. The park operates year-round.

A first-of-its-kind upscale indoor waterpark, Nashville’s Soundwaves at Gaylord Opryland blends family fun with an elevated club vibe. At first glance, you’ll recognize this is not your typical indoor waterpark. The large atrium ceiling is supported by wood beams, filling the clean white interiors with sunlight by day and starry skies by night. The thought and care put into the modern design here is evident, with a sleek waterfall over the main pool, an adults-only indoor infinity pool, and decorative green walls throughout the waterpark. Being a waterpark, this has its share of thrills, with a family raft ride, body slides, and a double FlowRider surf simulator. The stylish park is open year-round, 20 minutes from Downtown Nashville.

With 22 locations nationwide, Great Wolf Lodge is the largest collection of indoor waterpark resorts in the U.S. These family-friendly resorts feature universally excellent indoor waterparks, along with restaurants, arcades, spas, and a long roster of children’s activities often led by the brand’s original animal characters. The waterparks feature high-thrill waterslides, lazy rivers, wave pools, and well-themed water playgrounds for children. The company continues to expand, recently adding its largest resort in Perryville, Maryland, with plans to add another resort in Mashantucket, Connecticut, in 2025.
