Zuni-Acoma Trail Road to McGaffey Lookout — Cibola National Forest High Rim via Oso Ridge
Zuni Mountains high rim above Gallup.
The Zuni Mountains don’t get the glory they deserve. This route climbs from McGaffey Lake — a small, pine-rimmed reservoir at 7,700 feet that’s been a local escape since the 1920s — up through Cibola National Forest along Forest Road 50 and the Oso Ridge connector to the McGaffey Lookout site near the high point of the range at roughly 8,600 feet. You’ll run graded dirt that turns to chunky basalt and embedded rock on the upper switchbacks, with deadfall a genuine hazard after winter. The views north over the Red Rock country toward the Painted Desert are worth every rattle.
This is a high-clearance route, not a technical rock crawl — a capable stock 4WD or aggressive all-terrain rig handles it fine in dry conditions, but the clay-heavy soils turn viciously slick after rain and in shoulder seasons. Snow can close the upper road October through May. No permits required. Fuel up in Gallup (25 miles west) — there’s nothing out here. Dispersed camping is legal on National Forest land; a few established clearings exist near the lower FR 50 corridor. Cell service is nonexistent on the ridge.

Frequently asked questions
Can a stock 4Runner or Tacoma handle this trail without any mods?
Yes — a stock 4WD with decent ground clearance is the stated minimum. Rocky sections and eroded dirt roads are manageable unmodified, but aired-down tires help. Lifted rigs will have an easier time on the rougher stretches near the rim.
When does the trail typically open and close each year?
Best window is June through October. Snow and mud can close or badly chew up these dirt and gravel roads from November through May. Check with the Cibola NF Mount Taylor Ranger District before heading out in shoulder months.
Do I need a permit or is there a fee to run this route?
No permit required and no fee to drive the route through Cibola National Forest. Standard rules apply — pack it in, pack it out, and follow any posted fire restrictions, which are common in this part of New Mexico during dry summers.
What's the hardest section and what should I actually expect?
The roughest terrain is along the Oso Ridge high rim where rocky two-track, loose gravel, and eroded cuts demand attention. Nothing technical enough to require a locker on a moderate day, but at 8,600 ft the exposure and remote feel raise the stakes if something goes wrong.
Is there any water or cell service out there, and can I camp overnight?
Zero cell service for the entire route — plan accordingly and carry a satellite communicator. Dispersed camping is permitted throughout the national forest, so you can set up anywhere reasonable off the road. Carry all your own water; there are no reliable sources along the ridge.
