Overview
What it is
Spence Hot Spring is a small, natural soaking spot in the Santa Fe National Forest, reached by a short hike from a paved parking area off NM-4. The soaking area is typically a compact pool setup with rock edges, plus a small waterfall effect depending on flow and recent weather.
Water and conditions
The Forest Service describes Spence as warm rather than scalding, with water around 95°F (about 35°C), and notes that it has been cooling over recent years. Pool shape and depth can change after runoff, storms, and heavy use. Expect a natural pool, not a maintained basin, and plan for crowding at peak times.
Setting
You are in pine forest in the Jemez Mountains, which means cooler air than the desert lowlands and a real shoulder-season swing, warm days and cold evenings.
Location & Access
Where it is
Spence sits along NM-4 a few miles north of Jemez Springs. The Forest Service notes there is no sign for the spring itself, so use the trailhead and your map rather than looking for a big hot-springs marker.
Trailhead and hike
Parking is in a paved lot, then you hike a short distance to the soaking area. The trail is straightforward, but the last approach can be slick or muddy depending on weather. Poison ivy is present along the trail in season, so long pants can be a good idea if you are sensitive.
What to bring
Bring a swimsuit, a small towel, and footwear with traction. Potable water is not available at the site, so carry your own. The Forest Service prohibits glass containers, and also prohibits camping and campfires along the trail and at the spring, plan your visit as a true day stop.
Suitability & Accessibility
Best for
Spence is best for people who want a quick, natural soak without a long hike or rough road commitment. It is popular for a reason, the warm water feels good after a short walk, and you can be back at your car quickly if weather shifts.
Not a great fit for
This is not a place for anyone needing smooth, barrier-free access. The hike and uneven pool edges make it tough for many mobility limitations. It is also not a good “little kids” spot in practice, the pool is small, footing is uneven, and etiquette depends on other visitors being considerate.
Expectations vs reality
On busy days, you may be sharing a small pool with strangers at close range. If that sounds miserable, go early, go midweek, or pick a managed facility instead.
Safety & Etiquette
Water quality and nose safety
The Forest Service states that water quality is not monitored and warns visitors to avoid getting water in their noses to reduce risk from Naegleria fowleri, an amoeba associated with warm freshwater. Keep your head above water and do not splash water into faces.
Legal and on-site rules
The Forest Service states nudity is a violation of state law and that violators will be cited. Keep a swimsuit on. Also follow the no-glass rule, and do not light fires or attempt to camp at the spring.
Etiquette that keeps it usable
Spence stays pleasant when people keep it simple: pack out trash, keep voices low, do not soap up in the pool, and limit your time if others are waiting. If you move rocks, put them back before you leave, and never block water flow in a way that causes erosion.
