About Our Site - Hot Springs State Park
 

Over colorful terraces along the Big Horn River at Thermopolis flows water from mineral hot springs. More than 1.8 million gallons flow over the terrace every 24 hours at a constant temperature of 128 degrees Fahrenheit. The park has a free bath house where the water is maintained at 104 degrees for therapeutic bathing. Hot Springs has 6.2 miles of universally accessible trails and hiking trails. It is a full-service park with comfort stations, a volksmarch trail, fishing, and a boat ramp. One of the reservable group picnic shelters is located here. Hot Springs is a day-use park.

Bison-Baby-027

The Hot Springs State Park bison herd is the central herd for the Wyoming State Parks. During the late fall and winter months, the park bison are fed a daily supplement to insure good health. This feeding usually occurs at 8:30 a.m., giving the off-season visitor the unique opportunity to view the "Monarch of the Plains," up close. Please remember that bison should be viewed ONLY while you remain in your vehicle.

The suspension foot bridge across the Bighorn River is commonly called "The Swinging Bridge." The bridge offers a unique vantage point from which to view the Bighorn River and mineral terrace. Hot Springs State Park has long been known for its beautiful summer flower gardens. Make a point to bring your camera with you and capture the exciting splash of color all summer long.

There are three large group picnic shelters in the park available by reservation. These are very popular and heavily used. Contact park headquarters as soon as you can to reserve a shelter for your event and also, inquire if your group needs a park liquor permit.

Hot Springs State Park to Complete Improvements at State Bath House Outdoor Pool

THERMOPOLIS, Wyo. — Aug. 21, 2026 — Wyoming State Parks is announcing upcoming improvements to the outdoor soaking pool at the State Bath House in Hot Springs State Park. The outdoor soaking pool will temporarily close beginning Aug. 24 for approximately one month while several accessibility and safety improvements are completed.


The project will include installation of a new ADA-compliant pool lift chair, concrete improvements, and new handrails designed to meet current safety standards. Crews will also install a new sidewalk heating system to help reduce snow and ice accumulation around the pool area, providing a safer and more comfortable experience for visitors during the winter months.


“These improvements are an important investment in the State Bath House and the experience we provide our visitors,” said Christopher Delay, superintendent of Hot Springs State Park. “We appreciate everyone’s patience during the temporary closure and look forward to reopening the outdoor pool with improvements that will enhance safety and accessibility.”


The indoor soaking pool will remain open throughout construction during regular State Bath House hours: Monday through Saturday, 8 a.m. to 7 p.m., and Sunday, noon to 7 p.m.


The State Bath House is a free public facility. Visitors can also continue to enjoy Hot Springs State Park’s other amenities, including more than six miles of trails, scenic picnic areas, and the park’s central bison herd.


Construction is expected to take approximately one month. Visitors are encouraged to check for updates before their visit.
