Relaxing — deep, immediate muscle release.

Radium Hot Springs near the small ranching community of Radium, Colorado, in the Colorado River headwaters between Kremmling and State Bridge in Grand County, is a roadside thermal spring accessed on the banks of the Colorado River in a landscape of sage-covered canyon terrain typical of the Colorado Plateau's transition zone. The radon-bearing mineral springs, which give the town its name and emerge at bathing temperatures into a simple natural pool accessible from the highway, represent the informal end of America's thermal bathing culture — no infrastructure, no admission charge, just a hot spring on a riverbank in the western wilderness. The surrounding landscape of the Colorado River canyon, with its outstanding trout fishing, the Gore Range beyond and the massive Routt National Forest, provides a quintessentially Western American outdoor context. The broader Grand County region, encompassing Rocky Mountain National Park and the winter park ski area, is one of Colorado's great outdoor recreation destinations.
