Natural Wonder at Hot Springs State Park, Thermopolis, Wyoming

Hot Springs State Park in Thermopolis offers a rare geothermal experience in the heart of Wyoming. Famous for containing the world’s largest mineral hot spring, the park attracts visitors with its unique combination of natural beauty and healing waters. Each day, over a million gallons of 135°F mineral-laden water flow from Big Spring, creating vast terraces of travertine deposits in vivid shades of white, cream, and rust. These terraces form a striking backdrop unlike any other in the region.

The park spans a large area complete with walking trails, a swinging suspension bridge over the Bighorn River, and scenic picnic spots. Visitors often spot buffalo peacefully grazing near the mineral formations, adding a touch of wildlife to the landscape. Beyond its natural treasures, Hot Springs State Park carries cultural significance. The land was originally gifted to Wyoming in 1897 by the Shoshone and Arapaho tribes under the condition that access to the mineral baths remain free to the public, preserving a valuable connection between nature and community.

The Free Bath House invites visitors to soak in the therapeutic springs without charge, offering both indoor and outdoor pools that allow guests to relax in naturally heated water. Amenities are practical and visitor-focused, including ramps for accessibility and clean facilities. The park’s quiet trails, with options like the nearby Spirit Trail and the route across the swinging bridge, reveal peaceful views of the mineral terraces and river. Whether visiting for healing waters, gentle hikes, or wildlife viewing, Hot Springs State Park provides a distinctive, rejuvenating experience in Wyoming’s outdoors.
