Worlds Largest Mineral Hot Spring
At the center of all the activities in Hot Springs State Park is the Big Spring. The turquoise and green mineral-laden spring issues 3.6 million gallons of water per day at a scorching 127 degrees. The water contains at least 27 different minerals and feeds all the attractions within the park. The practice of using natural mineral water for the treatment or cure of disease is known as “balneology.”
Soaking in highly concentrated mineral water is thought to have many health benefits such as increased body temperature, which aids in killing harmful germs and viruses, eliminate toxins, increase blood flow and circulation, increase metabolism, and absorb essential minerals.
Whether you are coming to Thermopolis for the healing waters or just to have a family fun day, we have three great options for your swimming pleasure. None of our water are treated with chlorine and are all-natural, just the way nature intended!
Wyoming State Bathhouse
Our visitors say it best… My favorite part of Hot Springs State Park is the free Wyoming State Bath House. 20-minute soaks are allowed (every two hours if you are so inclined). The hot mineral waters are a balm to the skin, muscles, and psyche. It’s very quiet here, and people tend to converse softly or just silently relax. The view of the mineral terraces is lovely. I always feel so relaxed after a soak here. We come every time we are in Thermopolis.
Star Plunge
Since 1900, the Star Plunge has been a popular destination for travelers and locals alike. Their main attractions include indoor and outdoor pools & hot tubs, and exciting water slides. Let off some steam in their vapor cave, stay in shape in the fitness & weight room, or explore their gift shop. Other highlights include the Basketball Hoop, Sun Decks, Water Jets, Baby Pool, Fountain Waterfall, Tanning, Game Room, and Snack Bar.
Helle’s Teepee Pools
The Golden Dome is an icon of Thermopolis and is one of the most exciting things to see when you are on your way to the Hot Springs as you know the fun is near. The Teepee features an indoor pool, which includes a main pool with a waterfall, slide, baby pool, hot tubs, steam room, and dry sauna. Outside you will find another pool, hot tubs, and a water slide. The slide is open from Memorial Day to Labor Day.
