Spence Hot Springs
Spence Hot Springs emerges at 7,332 feet in the Santa Fe National Forest with 100°F water — 52°F above the local average. Total dissolved solids measure 224 mg/L with low calcium (6 mg/L) and sodium (55 mg/L) at pH 7.3, producing unusually soft thermal water. The springs are on open-access Forest Service land, reached by a short uphill walk from the parking area on Highway 4.
The springs surface on a forested hillside above the East Fork of the Jemez River in the southern Jemez Mountains. Dense Ponderosa pine and Douglas fir surround the pools, which sit on a slope with views down through the canyon. At this elevation, annual precipitation reaches 17.7 inches with 42.4 inches of snow, creating a true montane climate. The Valles Caldera — a 13-mile-wide volcanic collapse structure — lies just to the north, driving the geothermal activity that feeds these springs. Redondo Campground sits only 1.4 km away.
Spence Hot Springs takes its name from a local homesteader or prospector, though exact biographical details are scarce. The springs have been a popular soaking destination since at least the mid-20th century. Located within the Jemez National Recreation Area, the Forest Service has periodically managed access to address erosion and overuse. The site lies within the broader Valles Caldera volcanic system, one of North America's major caldera complexes.
The trail from the parking lot on Highway 4 climbs steeply for about 245 meters — wear sturdy footwear. At 7,300 feet, afternoon thunderstorms are common from July through September, and winter brings over 42 inches of snow; check road conditions before driving. Redondo Campground is just 1.4 km away and is reservable. No glass containers. The Forest Service enforces a clothing-optional policy prohibition — check current regulations before visiting. Bandelier National Monument and the Valles Caldera are both within driving distance.
