Star Plunge, Hellie’s TePee Pools, Wyoming State Bath House

Star Plunge

A right of passage for first-time visitors to Thermopolis is to swim and soak in the three iconic, hot spring-fed facilities within Hot Springs State Park. Once you and your family have completed the trifecta of hot mineral water fun and relaxation, you’ll have something in common with just about every other person who has visited Thermopolis! The trifecta includes two privately owned pool/spa/water park combination facilities (the Star Plunge and the Hellie’s TePee Pools) and the free, public Wyoming State Bath House. Both the Star Plunge and the TePee Spa feature large indoor and outdoor pools, exhilarating water slides, hot tubs, steam rooms, saunas, swim suit and towel rentals and ample lounge and sunbathing areas. The Star Plunge touts one of the world’s longest water slides–the Super Star 500. This 500 foot, twisting and turning water slide pumps nearly 2,400 gallons of water per minute down its open-top flume. In addition, the Star Plunge is home to the Blue Thunder Run, a 330 ft. all-weather hydro tube and the 60 ft. Lil’ Dipper for younger children. Over at Hellie’s TePee Pools, visitors are sure to be thrilled by a 272 ft. outdoor water slide as well as a 162 ft. indoor hydro tube. The Wyoming State Bath House is located between the TePee Pools and the Star Plunge. It’s filled with 100% mineral water, and no chemicals are ever added. Best of all, admission to the Bath House is free to the general public! No Thermopolis trip is complete without experiencing one or all of these three mineral attractions, but don’t stop there! Thermopolis offers so much more for the entire family!

Did you know . . .
The Star Plunge’s steam room is actually a “Vapor Cave” cut into the adjacent hillside. Hot mineral water gushes out of a naturally-formed fountain within the cave and produces enough heat to keep the cave at 118 degrees, creating steam.

Did you know . . .
The Wyoming State Bath House does not charge admission thanks to a stipulation in a treaty with the Eastern Shoshone and Northern Arapaho Native American tribes. In 1896, a treaty was signed, committing to sell ten square miles, including Hot Springs State Park, to the United States government. Chief Washakie of the Shoshones and Chief Sharp Nose of the Arapaho stipulated that a portion of the hot healing mineral waters were to remain free to the people. In 1899, the Wyoming Legislature specified that one-quarter of the water from the Big Spring that feeds the pools in the park would be free to the public.
