THERMOPOLIS, Wyo. – May 7, 2026 – Construction on the boardwalk at Hot Springs State Park is scheduled to begin the week of May 11, with work expected to continue through late August.

The project will involve a full replacement of the existing boardwalk, which is approximately 25 years old. Over time, the structure has begun to deteriorate, reducing water flow across the park’s iconic mineral terraces.

For the safety of visitors and to allow for efficient construction, the boardwalk will be closed to the public for the duration of the project. Visitors are encouraged to follow all posted signage and respect closure areas while work is underway.

“This project is an important investment in preserving both visitor access and the natural features that make Hot Springs State Park unique,” said Chris Delay, superintendent of Hot Springs State Park. “We appreciate the public’s patience as we complete these necessary improvements.”

Hot Springs State Park remains open during construction, and visitors are encouraged to continue enjoying the park’s many amenities. Nestled along the Big Horn River, the park offers a wide range of recreational opportunities, including viewing the resident bison herd, relaxing in the State Bath House’s mineral waters, picnicking in designated areas, and accessing the river for fishing and other water activities.

The park features more than 6 miles of trails, allowing visitors to explore the surrounding landscape. Seasonal programs and interpretive offerings are also available throughout the year.

The park’s mineral hot springs produce more than 3 million gallons of water daily, maintaining a constant temperature of 128 degrees Fahrenheit. The free State Bath House offers therapeutic soaking at a comfortable 104 degrees and is open year-round. Starting May 15, the Bath House hours will be Monday-Saturday from 8 a.m. - 7 p.m., and Sundays from noon - 7 p.m. 

Hot Springs State Park remains a vibrant destination for both relaxation and outdoor recreation, and Wyoming State Parks encourages visitors to explore all areas that remain accessible during construction.
