Location
Tucked into the folds of north-central New Mexico's volcanic highlands, the Jemez Springs area delivers one of the Southwest's most rewarding collections of natural soaking and swimming destinations. Spread across the Santa Fe National Forest along the winding corridor of Route 4, these unofficial sites range from steaming hillside hot springs to cool, clear river pools shaded by cottonwoods and ponderosa pines. The Jemez Mountains rise around you in layers of red canyon wall and pine-covered ridgeline, giving the entire area a dramatic, ancient quality that feels worlds away from Albuquerque's city sprawl just an hour to the south.
The landscape here is the product of volcanic geology on a grand scale. Mineral-rich water seeps up through fractured basalt and rhyolite, feeding pools that range from pleasantly warm to genuinely hot. At Soda Dam, you'll find one of the most visually arresting geological formations in New Mexico — a calcium carbonate travertine dam spanning the Jemez River, complete with its own mineral-stained waterfall. Nearby, the historic Gilman Tunnels carve through sheer canyon rock, and the river below offers secluded, shaded swimming spots with a sense of discovery that never gets old. Each season transforms the canyon differently: wildflowers carpet the slopes in spring, summer brings lush green canopies and warm soaking weather, autumn ignites the hillsides in gold and amber, and winter turns the hot springs into steaming sanctuaries against the cold mountain air.
The experience varies meaningfully from site to site. Spence Hot Springs is the most accessible — a short, easy trail leads to terraced rock pools perched above the Jemez River, where warm thermal water flows into tiered basins with views across the forested canyon. It draws a lively, social crowd and is the best introduction for first-timers. McCauley Warm Springs rewards a moderate hike with clear, blue-green pools that feel almost surreal against the surrounding pine forest — the water is comfortably warm rather than scalding, making it ideal for a long, relaxed soak. For those willing to earn their reward, San Antonio Hot Springs requires a longer approach and possibly a high-clearance vehicle, but the dramatic mountain views and deeply private atmosphere are unmatched. Facilities throughout the area are nonexistent, so come prepared and leave no trace.
All sites listed here are free to access and operate as unofficial recreational areas within the Santa Fe National Forest — there are no lifeguards or safety personnel on site, so swim and soak at your own discretion. There are no restrooms or developed amenities at the springs themselves. If you're looking to make a weekend of it, several campgrounds line Route 4 through the national forest. Vista Linda Campground, located south of the town of Jemez Springs on Route 4, is a local favorite and reportedly has a swimming hole near site number 8. The town of Jemez Springs itself offers a quiet base with local character, while Los Alamos to the northeast and Albuquerque to the south provide full services, gear shops, and lodging. Come in summer for warm swimming, or winter for the unique pleasure of a hot soak in a snow-dusted canyon.
