San Francisco River Hot Springs are natural geothermal springs along the San Francisco River in Grant County, New Mexico, near the historic mining ghost town of Mogollon, where hot spring-fed pools emerge from the volcanic geology of the Mogollon Highlands in a remote canyon landscape that requires careful river navigation to access in the extraordinary wilderness of the Gila National Forest. The bicarbonate-enriched thermal waters here flow into natural riverside pools along one of the American Southwest's most scenically magnificent and least-visited wild rivers, whose canyon walls of volcanic tuff and rhyolite preserve the dramatic geology of the ancient Mogollon Rim volcanic field. Bathing at San Francisco River Hot Springs combines the therapeutic experience of natural mineral spring bathing with immersion in the extraordinary geological and historical landscape of the New Mexico Mogollon country, where the legacy of ancient indigenous settlement, nineteenth-century silver mining, and the pristine wilderness preserved by Aldo Leopold's visionary conservation advocacy converge in one of the American Southwest's most remarkable natural environments.

Insider tip — San Francisco River Hot Springs occupy a remote canyon in the Gila National Forest near Glenwood, New Mexico, accessible only via a riverside trail requiring multiple stream crossings. Iron-bearing geothermal water seeps from volcanic intrusions at the canyon wall, draining into riverside soaking pools at around 38°C. The New Mexico desert sky visible from the canyon bottom is one of the darkest in the continental US, ideal for stargazing after the spring cools with nightfall. Black bear sightings on the trail are not uncommon.
