McCauley Hot Springs emerges at 99 °F within Santa Fe National Forest at a notable 7,360 feet elevation in the Jemez Mountains. USGS measurements record 31 °C with alkaline pH of 8.0 and low mineralization. The spring sits about 950 meters from the nearest road, requiring a moderate hike through mixed conifer forest. It is open to the public on US Forest Service land.

The spring occupies a forested slope in the volcanic Jemez Mountains of Sandoval County. At 7,360 feet, ponderosa pine and mixed conifer dominate the surrounding woodland. The Jemez River drainage lies below, and the Valles Caldera — one of North America's largest volcanic calderas — spreads to the north. The area receives 17.7 inches of rain and over 42 inches of snow annually. Battleship Rock, a prominent volcanic formation, stands nearby along NM Highway 4. The East Fork of the Jemez River runs through the canyon below.

History of Mccauley Hot Springs

The spring is also called McCauley Warm Springs and Battleship Rock Hot Springs, the latter referencing the towering tuff formation along the highway. Thermal activity here results from the Valles Caldera volcanic system, which last erupted roughly 1.25 million years ago but still drives significant geothermal heating. The Forest Service maintains the area as open access. Jemez Pueblo lies downstream, and the broader Jemez Springs community has a long tradition of hot spring bathing dating to pre-Columbian use.

The trail to the spring gains elevation through forest and takes roughly 30 minutes one way. Visit between May and October to avoid heavy snow — the 7,360-foot elevation receives over 42 inches annually. Jemez Falls Campground is only 1.9 km away and accepts reservations. Bring layers; nights are cold even in summer at this altitude. NM Highway 4 through the Jemez corridor can be congested on summer weekends. Combine with a stop at Battleship Rock or Soda Dam along the same road.
