Forest Road 10 (Jemez Mountains)
Volcanic highlands through the Jemez wilderness
Forest Road 10 cuts a rugged line through the volcanic heart of the Jemez Mountains, starting near Fenton Lake and winding southeast toward Los Alamos. This 30-mile forest service road crosses the massive Valles Caldera rim, threading between ancient volcanic domes and through dense stands of aspen and ponderosa pine. The route passes Redondo Peak, the collapsed dome at the caldera’s center, and offers glimpses into one of the largest volcanic complexes in North America.
This is a solid moderate trail requiring high-clearance 4WD, especially during spring snowmelt and summer monsoons when creek crossings can turn nasty. Best tackled May through October when snow clears above 9,000 feet. No permits needed, but bring extra fuel and water – services are nonexistent between Cuba and Los Alamos. The payoff is solitude in volcanic country few see, with dispersed camping opportunities and access to hot springs if you know where to look.

Frequently asked questions
Can a stock Tacoma or 4Runner run FR 10 without modifications?
Yes, a stock high-clearance 4WD handles it fine under normal dry conditions. Lifted rigs aren't required, but low-range and decent all-terrains are — the rocky volcanic surface chews through street tires.
When does FR 10 open after winter and is it ever closed in summer?
The route is typically accessible May through October, but snow can linger at 10,000 ft well into May. Santa Fe National Forest also closes roads during fire restrictions or after heavy monsoon damage — check with the Jemez Ranger District before you go.
Do I need a permit or pay any fees to drive FR 10?
No permit or fee required to drive or camp dispersed on this Santa Fe National Forest road. Standard dispersed camping rules apply — 14-day stay limit, 300 feet from water sources and roads.
What's the hardest section of the route and what makes it technical?
The roughest stretches involve loose volcanic rock and eroded drainage crossings mid-route. Nothing requires a spotter or winch under dry conditions, but wet clay over basalt turns slick fast — that's where moderate becomes a real conversation.
Are the water crossings on FR 10 actual obstacles or just wet spots?
Most are shallow seasonal crossings that are non-issues in summer, but spring runoff or post-monsoon rain can raise them enough to matter. There's no bridge infrastructure on the remote sections, so if you're running after heavy rain, plan to air down and probe depth before committing.
