Water Parks in Wyoming

Wyoming is wide open spaces and natural wonders, and the water park scene here reflects a state where Yellowstone and the Grand Tetons are the main attractions. With a total population under 600,000 -- the least populated state in the country -- the economics of large-scale water parks simply don't work here. But what Wyoming does have is genuinely unique. Star Plunge in Thermopolis is the highlight, and it's unlike anything you'll find in a traditional water park guide. Thermopolis sits on what's claimed to be the world's largest mineral hot springs, and Star Plunge lets you experience those natural hot springs alongside water slides and pools. The combination of geothermal springs and water park attractions in a small Wyoming town is the kind of thing that could only happen in this state. Hot Springs State Park, which surrounds the springs, adds hiking and bison viewing to the experience. Beyond Star Plunge, Wyoming's water park options are extremely limited. The state's small population and vast distances between towns mean that most families rely on community pools, natural swimming holes, and the occasional trip to a neighboring state for a bigger water park experience. For families visiting Yellowstone or Grand Teton National Park -- which accounts for a huge percentage of Wyoming tourism -- the closest substantial water parks are in Montana, Idaho, or Utah. The drive times are significant, which is just the reality of the northern Rockies. Wyoming summers are short but can be surprisingly warm in the lower elevations. Casper, Cheyenne, and the eastern plains regularly see temperatures in the 80s and 90s from June through August. The mountain areas and Yellowstone plateau run much cooler. The outdoor window for any water activities is roughly late June through mid-August. One thing Wyoming does have in abundance is natural water recreation. The rivers, lakes, and reservoirs throughout the state offer swimming, tubing, and boating that no manufactured park can match. Fremont Lake near Pinedale, Glendo Reservoir, and the Bighorn River are just a few examples. Practical tip: if you're visiting Thermopolis, don't just hit Star Plunge and leave. Hot Springs State Park has free public soaking in the mineral hot springs -- actual free hot springs, which is remarkable. Budget a full day for Thermopolis to soak in the free springs, try Star Plunge, and visit the Wyoming Dinosaur Center, which is also in town. It's one of the most underrated day trips in the state, and it gives your family a break from the heavy-duty national park hiking that dominates most Wyoming vacations.
