Star Plunge

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. The on-site snack bar covers the basics, but you might want to grab lunch in town afterward.

Plan to spend 3-4 hours here, and definitely take time to just float and soak. The minerals are supposed to be great for your skin and joints, and honestly, after a long day of hiking in Wyoming, that hot springs soak hits different than any regular pool.
