Our team at Roam States has meticulously explored this unique Wyoming gem to bring you the most confident and specific advice for your visit. Forget generic travel fluff; we're here to equip you with all the verified 2026 facts on hours, fees, parking, and must-do activities so you can plan a truly unforgettable trip to this extraordinary destination.
Is It Worth Visiting?
Absolutely, is Hot Springs State Park worth visiting? Our emphatic answer is yes. This isn't just another park; it's a geological marvel and a historical treasure. Imagine over 1.8 million gallons of mineral-rich water, heated to a constant 128 degrees Fahrenheit, cascading over vibrant travertine terraces every 24 hours. The visual spectacle alone, with the colorful mineral deposits painting the landscape in hues of orange, green, and white, is reason enough to make the journey. Beyond the stunning scenery, the park offers a rare opportunity for free therapeutic soaking in the State Bath House, a tradition upheld by an 1896 treaty with the Eastern Shoshone and Northern Arapaho tribes. This commitment to public access to the healing waters sets Hot Springs State Park apart. We consider it a must-see for anyone exploring the diverse wonders of Wyoming.
For those questioning, "is Hot Springs State Park worth visiting?", consider its blend of natural beauty, historical significance, and accessible recreation. It's a place where you can witness the raw power of geothermal activity, relax in mineral waters, and observe Wyoming's state bison herd, all within a compact and easily navigable area. It provides a refreshing contrast to the grandeur of places like Yellowstone National Park but offers its own distinct charm and accessibility.
Who It's Best For
Hot Springs State Park caters to a surprisingly broad range of travelers, making it an ideal stop for almost anyone exploring Wyoming. Our team finds it particularly well-suited for:
- Families with Children: The free State Bath House, gentle walking trails, and the excitement of spotting the park's resident bison herd make it a fantastic family destination. The nearby commercial pools, Hellie's TePee Pools and Star Plunge, offer additional water slides and amenities for kids (though these require an admission fee).

Top Things to Do
There's a surprising array of things to do at Hot Springs State Park, offering a blend of relaxation, nature, and history. Our team recommends dedicating at least half a day, if not a full day, to fully experience its offerings.
Soak in the Free State Bath House
This is arguably the crown jewel of the park and one of the top things to do at Hot Springs State Park. The State Bath House provides free public access to the mineral-rich waters, maintained at a therapeutic 104 degrees Fahrenheit. The 1896 treaty ensures that this access remains free to the public in perpetuity. Visitors can enjoy a 20-minute soak in either the indoor or outdoor pools. As of 2026, the Bath House hours are generally Monday-Saturday from 8 a.m. to 7 p.m., and Sundays from noon to 7 p.m. during the summer season (starting May 15). Winter hours are typically Monday-Saturday from 8 a.m. to 5:30 p.m. and Sundays from noon to 5:30 p.m. It's closed on winter holidays and open noon to 5:30 p.m. on summer holidays. No advance reservations are required.
Explore the Rainbow Terraces
Just behind the State Bath House, you'll find the stunning Rainbow Terraces, formed by centuries of mineral deposits from the hot springs. These colorful travertine formations are reminiscent of a smaller version of Yellowstone's Mammoth Hot Springs. Follow the boardwalks and paved paths for up-close views of the vibrant pools and cascading hot water. More than 3 million gallons of 135-degree Fahrenheit water flow over these terraces daily.
Walk Across the Swinging Bridge
For a unique perspective of the Big Horn River and the mineral terraces, cross the iconic Swinging Bridge. This suspension footbridge offers a slightly "unsettling" but memorable experience as it sways gently over the river. It's an excellent spot for photos and to appreciate the scale of the river and the surrounding landscape.
Wildlife Viewing: The State Bison Herd
Hot Springs State Park is home to Wyoming's central state bison herd, which often numbers around 15-20 animals. You can often spot these magnificent creatures roaming in designated pastures within the park. During late fall and winter, visitors may have the unique opportunity to see the bison being fed around 8:30 a.m. Remember to view bison only from the safety of your vehicle.
Hot Springs State Park Hiking Trails
The park offers over 6 miles of universally accessible trails, making it easy for most visitors to explore on foot. The Hot Springs State Park hiking trails include paved paths and boardwalks that wind through the mineral terraces, along the Big Horn River, and to various viewpoints. The Mineral Hot Springs Loop Trail is a popular easy, 0.6-mile loop that showcases the vibrant springs and formations. These Hot Springs State Park hiking trails provide excellent opportunities for a leisurely stroll or a more invigorating walk, allowing you to immerse yourself in the natural beauty of the area. Be sure to check out the Volksmarch trail as well.
Boating & Fishing on the Big Horn River
The Big Horn River, which flows through the park, is a "blue-ribbon trout fishery," offering excellent opportunities for fishing, particularly for brown trout, rainbow trout, and cutthroat trout. The park also provides boat ramps and docks for those looking to enjoy the river by boat. Fishing ponds for catfish and carp are also available.
Picnicking and Gardens
Hot Springs State Park is well-equipped with comfort stations and numerous picnic areas, including three large group picnic shelters that can be reserved in advance. The park is also known for its beautiful summer flower gardens, adding another splash of color to the landscape.
Best Time to Visit
Our team believes that Hot Springs State Park offers something special in every season, but the "best" time depends on your priorities.
- Summer (June-August): This is the most popular time, with warm weather perfect for outdoor activities and longer daylight hours. The park's flower gardens are in full bloom. However, it's also the busiest, so expect more crowds, especially at the State Bath House. Temperatures can reach into the 80s and 90s Fahrenheit.
- Spring (April-May): A beautiful time to visit as the landscape comes alive with greenery and fewer crowds than summer. The weather is generally mild, though it can be unpredictable. This is a great time for hiking and enjoying the fresh air.
- Fall (September-October): The cooler temperatures and changing leaves make for a picturesque visit. Crowds begin to thin, offering a more tranquil experience. Wildlife viewing, particularly of the bison herd, can be excellent.
- Winter (November-March): For a truly unique and serene experience, consider a winter visit. Soaking in the warm mineral waters while surrounded by snow is magical. The park is less crowded, and you might have the chance to see the bison up close during their morning feeding. Be aware that some facilities or services might have reduced hours, and the Bath House is closed on Thanksgiving and Christmas Day.
Overall, for a balance of good weather and manageable crowds, we often recommend late spring or early fall. However, if your primary goal is a peaceful soak and wildlife viewing, winter can be incredibly rewarding.
