About Each Park
Star Plunge
Wyoming
Star Plunge in Thermopolis is Wyoming's original water park, and it's got a completely different vibe from your typical commercial splash zone. This place runs on natural hot springs water, which means you're swimming in the same geothermal goodness that made Thermopolis famous in the first place. The main attraction is the giant outdoor pool filled with naturally heated mineral water that stays warm year-round - we're talking 104°F straight from the ground. You'll also find a couple of solid water slides that dump you right into the hot springs pool, plus a separate cooler swimming area for when you need a break from the heat. The park keeps things simple but effective with a lazy river that's perfect for floating, and a decent kids' area with smaller slides and splash features. What really sets Star Plunge apart is that therapeutic hot springs experience. You can actually soak in the same waters that people have been using for healing for over a century. It's especially amazing during Wyoming's brutal winters when you can swim outside in steaming hot water while snow falls around you. The facility isn't huge or flashy, but it's clean and well-maintained with that classic small-town feel. Families love it because the natural mineral water is gentle on skin, and the smaller size means parents can easily keep track of kids. Bring water shoes since the concrete can get hot, and don't expect fancy amenities - this is more about the unique natural experience than resort-style luxury.…

Big Splash at The Bighorn Resort gives Billings families a solid water park experience without the overwhelming crowds you'd find at mega-parks. The wave pool here is the main draw, generating decent-sized waves that kids love to jump in while parents can actually relax nearby without losing sight of them. The water slides range from gentle slopes perfect for younger kids to a few steeper drops that'll get your heart pumping, though don't expect record-breaking heights or complex tube rides. What I really appreciate about Big Splash is how well-designed the kiddie area is. The splash pad has colorful water features at toddler height, and there's enough shallow water play that parents can sit right at the edge while little ones explore safely. The layout makes sense too - you're never walking forever between attractions like at some poorly planned parks. Since this is part of The Bighorn Resort, everything feels well-maintained and clean. The staff keeps a good eye on safety without being overly strict about every little thing. Food options are typical water park fare, but the portions are decent and prices aren't completely outrageous. I'd recommend arriving when they open, especially on hot summer weekends, to claim your spot and avoid the afternoon rush. Bring reef-safe sunscreen because Montana sun at this altitude can sneak up on you fast. The park works best for families with kids under 12 - teens might get bored after a few hours since there aren't any major thrill rides. But for…
