Green River Hot Springs are situated near Green River, Wyoming, a historic city on the Green River — a major tributary of the Colorado and the starting point of John Wesley Powell's legendary 1869 and 1872 expeditions that first mapped the Colorado River canyons including the Grand Canyon, expeditions that rank among the greatest acts of exploration in American history. The Flaming Gorge, where the Green River cuts through vermilion sandstone canyons just south of town, and the Red Canyon area provide spectacular scenery in a region where the geology reads like an open textbook of the Colorado Plateau's layered past. The hot springs near Green River draw on hydrothermal resources in the sedimentary basin and fault systems of the Wyoming portion of the Colorado Plateau, offering mineral bathing in a historically charged river landscape where Powell's audacious river explorations permanently changed American geography's understanding of the Southwest.

Insider tip — Green River Hot Springs surfaces near the confluence of Wyoming's Green River and its tributaries, in the heart of the Wyoming Basin's high desert. The striking Flaming Gorge formations and Castle Rock butte loom over the valley, sculpted by millions of years of river incision. The warm mineral waters provide welcome relief after hiking the surrounding badlands terrain. Evening soaks with long desert sunsets are particularly rewarding in September.
