About the Springs
San Antonio Hot Springs, New Mexico is a free, undeveloped geothermal spring in the Santa Fe National Forest, approximately 12 miles north of Jemez Springs in the Jemez Mountains of northern New Mexico. Several primitive rock-lined pools sit at different elevations on a steep forested hillside, fed by source water emerging at approximately 129 degrees Fahrenheit. The upper pools are the hottest at around 105 to 110 degrees; the lower pools are progressively cooler. The pools have sandy and gravel bottoms, water is crystal-clear and odorless, and each pool cascades into the next. Views across the San Antonio Creek valley are considered among the most scenic of any accessible hot spring in New Mexico.
The springs sit within the Jemez Mountain volcanic system, part of the broader Valles Caldera volcanic complex. The Jemez area contains one of the highest concentrations of geothermal features in New Mexico, with multiple hot springs within a short drive. This site is one of the most popular due to its dramatic hillside setting and high water volume.
For visitors looking for hot springs near Jemez Springs New Mexico, this is the most visually spectacular free option in the area, though access depends on the seasonal status of Forest Road 376 and current road conditions.
Location & Access
Getting There
The springs are reached via Forest Road 376, off NM-126 in the Santa Fe National Forest. From Jemez Springs, drive north on NM-4 for approximately 6 miles to the NM-126 junction; turn left (west) and drive approximately 3 miles to the signed FR-376 junction; turn right (north) onto FR-376. The trailhead is approximately 5 miles north on FR-376. A high-clearance vehicle is strongly recommended; the road is rocky and rarely graded. Some drivers complete the road in standard vehicles but it is not advised.
Forest Road 376 is subject to seasonal closure during winter and spring; AllTrails notes the gate is typically closed January through June, though exact dates vary. When the gate is closed, visitors must walk or ski the full 5 miles from the NM-126 junction to the trailhead. From the trailhead at the end of FR-376, cross San Antonio Creek and hike approximately 0.7 miles up the steep hillside to the springs. Always confirm current road status with the Santa Fe National Forest Jemez Ranger District before visiting.
For visitors exploring hot springs near Jemez Springs New Mexico, FR-376 is accessed from the same NM-126 junction used to approach other Jemez Mountain springs, making a multi-spring day possible when road conditions allow.
Suitability & Accessibility
Who Should Visit
These springs suit experienced hikers and backcountry visitors prepared for the access challenges: a rough dirt road that may require high-clearance or 4WD, and a steep trail from the creek crossing to the pools. The springs are among the hottest and most visually impressive accessible hot springs in the Jemez Mountains, making the effort worthwhile for those who enjoy undeveloped geothermal settings. The combination of clear mountain water, dramatic hillside pools, and open valley views distinguishes the site from more heavily visited springs along the highway.
Clothing is widely understood to be optional and is the dominant local practice; families with older children who can manage the steep terrain are welcome. There is no minimum age restriction. Dogs are allowed on the trail on a leash. Day use only is the official designation; camping at or near the springs is prohibited. No facilities are available at the springs; bring everything you need.
For those seeking natural hot springs near Jemez Springs, this site offers the most dramatic soaking environment in the area. Winter visits with the gate closed require a full 10-plus mile round trip on snow or ice and are suitable only for experienced winter hikers with appropriate gear. Summer and fall visits via the open road are more accessible.
Safety & Etiquette
San Antonio Hot Springs Safety Tips
The most significant hazard at the pools themselves is the upper pool temperatures, which reach approximately 105 to 110 degrees Fahrenheit. This temperature can cause scalding burns on sustained contact. Always test the water before entering any pool and start with the lower, cooler pools if you are unsure. Never enter the area immediately below the spring source, where water can exceed 129 degrees. Move between pools to find a comfortable temperature and do not remain in the hottest pools for extended periods.
Forest Road 376 is the primary safety hazard for most visitors. The road is rocky and rarely maintained; vehicles can become stuck or damaged. A high-clearance vehicle is strongly recommended. Never attempt the road after heavy rain, as the surface becomes extremely slippery and crossings may be impassable. The gate is typically closed January through June. If the gate is closed and you attempt the walk-in, the round trip to the springs and back is over 10 miles on terrain that may include snow, ice, and mud; plan accordingly with appropriate gear, food, and water.
The trail from the creek to the springs is steep and exposed with no shade. Bring sun protection and more water than you expect to need, particularly in summer. There is no cell service in the area. Do not visit alone. The springs are designated for day use; do not camp at the site. Confirm current road status and fire restrictions with the Santa Fe National Forest Jemez Ranger District before your visit.
