Hot springs in the United States number at least 505 across this directory, spread through 25 states from the Rockies to the Pacific coast. Glenwood Hot Springs Pool anchors a Colorado resort town, while Chena Hot Springs Resort steams in the Alaskan interior near Fairbanks. 179 of the 505 listed here are free to soak, many on public land. The West holds the great majority.
The Rocky Mountain states hold the densest concentration of soaking pools in the country. Idaho leads with wild creekside pools along its rivers, and you can browse hot springs in Idaho, Colorado's resort and wild pools, and hot springs in Montana by state. Standouts include Strawberry Park Hot Springs near Steamboat Springs and Ojo Caliente Mineral Springs in New Mexico. More than 240 of the directory's listed springs sit across this mountain region.
The Pacific and Great Basin West gathers coastal, desert, and Sierra pools. California alone lists dozens, and travellers can open hot springs in California, Oregon's forest pools, hot springs in Nevada, and hot springs in Washington. Wild favourites include Travertine Hot Springs near Bridgeport and Umpqua Hot Springs above the North Umpqua River. Around 180 of the springs listed here lie in these western states.
Alaska and Hawaii add remote volcanic and geothermal soaks far from the mainland. Chena Hot Springs Resort near Fairbanks draws aurora visitors, and the state pages for hot springs in Alaska and hot springs in Hawaii cover the rest. Access is seasonal and often remote, with some reached by trail, boat, or small plane alone. A smaller set of the listed springs sits across these two states.
The East and South hold scattered historic spa towns rather than wild pools. Florida's warm artesian springs, the Ozark baths of hot springs in Arkansas, and sites across Texas and West Virginia round out the map. Many eastern springs are developed resorts or state-park pools rather than free backcountry soaks. The remaining listed springs are spread thinly across the eastern states.
American soaking splits between free wild springs on public land and developed resort pools, a balance few other countries keep. Roughly 179 of the 505 springs listed here are free, many managed by the Forest Service or found along backcountry trails in the West. Developed resorts add large pools, lodging, and year-round access at sites like Glenwood and Chena. These form the core of the wider hot springs in North America.
