1. Wilderness at the Smokies in Sevierville, Tennessee
We drove 30 minutes southeast from Knoxville to Sevierville.
Set against the backdrop of the Smoky Mountains, Wilderness at the Smokies was a theme park with its own climate. It's splashing fun here year-round! We grabbed an off season deal on airplane tickets from Austin to Knoxville and it was a great plan!
The Wild WaterDome had a retractable roof, but even on cloudy days, the light poured in.

Lodging is part of the fun here. You can get a standard hotel room or multi-room condos with kitchens if you have a big family or in-laws with you. Many rooms feature balconies or patios. Staying onsite is the best way to go because it gives you free access to the waterparks during your stay.
What about food? The resort has a wide variety of dining options to keep things easy. There's Hidden Trail Bar & Grill, Thirsty Miner Restaurant, or quick bites from the snack bars near the pools.
The highlight is, of course, the waterparks: Wild WaterDome (indoor, with a wave pool under a glass roof), Lake Wilderness (outdoor, with slides and a lazy river), and Salamander Springs (outdoor, with kid-friendly splash zones). There's also the Adventure Forest indoor park with mini golf, climbing walls, and laser tag.
If you have an extra day, head to Sevierville, Pigeon Forge, and Gatlinburg to check out attractions like Dollywood, dinner shows, shopping, and Great Smoky Mountains National Park.
2. Avalanche Bay in Boyne Falls, Michigan
We an hour from Traverse City to Boyne Falls, a northern Michigan town best known for its year-round outdoor adventures.
Inside this alpine-themed water park, it felt like the Swiss Alps met a tropical resort. Snow piled outside, but inside was all laughter and whooshing tubes. This one is not just one of the best indoor water parks in the USA, it's also Michigan's larges!
- What to Know Before Visiting Avalanche Bay
- Best Airport: Cherry Capital Airport (TVC) in Traverse City, or Pellston Regional Airport (PLN)
- How Many Days: 1–3, depending on whether you’re combining with skiing or resort activities
- Time of Year to Visit: Year-round
Inside the waterpark, highlights include the Rip Zone surf simulator, Vertigo Cannonbowl slide, and Splasherhorn play structure that dumps 800 gallons of water at once. Families can float on the lazy river, relax in hot tubs, or race down tube slides together.
Avalanche Bay is part of Boyne Mountain Resort, so staying onsite means waterpark access is just steps from your room, along with restaurants, a spa, and outdoor activities. It’s a true four-season destination where you can enjoy northern Michigan’s skiing, golfing, and hiking.
3. Great Wolf Lodge, Kansas City
Great Wolf Lodge, Kansas City is easy to get to, even if you are from out of town. It gives you a lot of options for a fun family vacation because it's near the Legends Outlets and Kansas Speedway.
The indoor waterpark is kept at a toasty 84 degrees year-round, making it just as fun in February as in July. Kids can also enjoy character meet-and-greets, evening story time in pajamas, and adventure games at the lodge.
- What to Know Before Visiting Great Wolf Lodge Kansas City

Dining is built into the resort experience. We liked the buffet- at Camp Critter Bar & Grille, Dunkin’ Donuts and Bear Paw Sweets & Eats. Legends Outlets nearby has even more dining options.
< The waterpark has tube slides, a lazy river, a giant water fort, and wave pools. There's MagiQuest interactive adventures, miniature golf, an arcade, and evening activities like dance parties and story time.
For us, the highlights were watching the kids splash for hours in the wave pool.
4. Kalahari Resorts and Conventions, Round Rock, Texas
We drove 25 minutes north from our home near Austin.
At 223,000 square feet, Kalahari in Round Rock is one of the largest indoor waterparks in the U.S. Amazingly, it's also just 45 minutes from my house near Austin, TX.
For families, it’s a guaranteed hit. We've celebrated birthday parties here in the winter or we got away for a bit of fun.
I love that restaurants, arcades, escape rooms, spa, shops, and convention halls all sit under one roof.
One downside I want to mention is that crowds are relentless on holidays and weekends. My kid loved it so all was well.
If you are from out of town, I recommend combining your trip to Kalahari with a night in an Austin hotel so that you can experience the culture, food, and music in our wonderful city.
5. Kalahari Resorts & Conventions, Wisconsin Dells
I drove 55 minutes north from Madison to Kalahari Resorts in Wisconsin Dells, the waterpark capital of the Midwest. You can race down towering waterslides, float the indoor lazy river, splash in the wave pool, or head into the huge arcade and indoor theme park for more action.
Parents can sneak off to the spa or enjoy a leisurely dinner while the kids keep playing, and with so many on-site restaurants and activities, it’s easy to settle in without ever leaving the resort.
Massive and somehow still intimate, Kalahari’s African-themed indoor water park had one of the largest wave pools I’d ever seen. I tried the Master Blaster uphill water coaster (twice), then soaked in a whirlpool that smelled faintly of eucalyptus. The snack bar served a grilled chicken sandwich with sweet barbecue sauce and pineapple slaw, warm and tangy in the best way. “This isn’t just a park,” I thought. “It’s a kingdom.”
6. Aquatopia at Camelback Lodge in Tannersville, Pennsylvania
We drove 1 hour 40 minutes north from Philadelphia to Aquatopia at Camelback Lodge, a Poconos escape built around one of the biggest indoor waterparks in the Northeast.
You can zip down twisting slides, float the lazy river, let the kids splash in the wave pool, or step outside for year-round mountain fun at Camelback—skiing in winter, zip lines and mountain coasters in summer. At night, the lodge makes it easy to wind down with family-friendly dining and cozy suites.

We drove 2 hours southwest from Washington, D.C. to Massanutten Resort, a four-season getaway tucked in Virginia’s Shenandoah Valley. You can ski and snowboard in winter, splash around at the massive indoor waterpark, hike on mountain trails with Blue Ridge views, or unwind with golf and a spa day.

8. Sahara Sam's in West Berlin, New Jersey
As a local, I dove 2 hours from NYC to Sahara Sam’s, an indoor and outdoor (during warm weather!) waterpark located in West Berlin, New Jersey.
Sahara Sam’s is designed as a day-trip destination rather than a full resort. That means you’ll find plenty of slides, pools, and attractions packed into the park, but no on-site hotel. Many families pair a visit here with other South Jersey or Philadelphia-area attractions for a complete getaway.

- Best Airport: Philadelphia International Airport (PHL), about 30 minutes away

The park has its own snack bars and concessions with pizza and burgers. Nearby Route 73 and Route 70 offer chain restaurants.
Sahara Sam’s has water slides, a lazy river, a wave pool, and a multi-level play structure with splash features. The indoor surf simulator is a favorite for older kids and teens. In summer, the outdoor waterpark adds a leisure pool, cabanas, and additional slides.
If you have time, check out the Adventure Aquarium in Camden, the Philadelphia Zoo, or the shops and restaurants at Cherry Hill Mall.
For us, the highlights were floating the lazy river on a chilly winter day.
9. Splash Lagoon Indoor Waterpark Resort in Erie, Pennsylvania
We drove 2 hours north from Pittsburgh to Splash Lagoon in Erie, an indoor tropical-themed waterpark that stays warm no matter the season.
One thing to know before you go: Splash Lagoon is connected to multiple partner hotels so I loved how many difference choices we had for an overnight stay. Overnight packages include waterpark passes, and the attached hotels offer everything from budget-friendly rooms to suites for larger groups.

For food, we liked the Lagoon Grill pizza, burgers, and salads right inside the park. The Surf Bar offers drinks for adults. Other restaurants line Peach Street just outside the waterpark, from local diners to popular chains.
The waterpark itself had a wave pool, lazy river, body and tube slides, and a large play structure with splash features for younger kids. Hurricane Hole and Black Hole slides are the most scary. The Treasure Island Arcade has over 100 games, and the ropes course and laser tag arena add even more to do.
Erie offers Presque Isle State Park, shopping, and family-friendly attractions nearby.
10. Great Wolf Lodge, Grapevine, TX
My second favorite indoor waterpark in Texas close to our house is Great Wolf Lodge Grapevine, Texas. This massive lodge combines the excitement of a year-round waterpark with themed suites, kid-focused entertainment, and plenty of dining all under one roof.
The 84-degree indoor waterpark offers slides, a wave pool, and splash zones for all ages. They have daily highlights like character appearances, story time, and adventure games.
