Lonesome Highway — Gila River Backcountry to Mogollon Ghost Town via Sandy Road
Shelf road to a ghost town above the Gila Wilderness.
State Road 159 from Glenwood, New Mexico toward Mogollon is paved to a point — then the pavement ends and the mountain gets serious. The last several miles to Mogollon are a narrow, steep, one-lane shelf road carved into the side of the Silver Creek drainage, with drop-offs that’ll make your passenger go quiet. Mogollon itself is one of the best-preserved silver mining ghost towns in the Southwest: a handful of original buildings, an old mill, and a population that hovers around a dozen people. The ride up is half the point — Silver Creek Canyon below you glitters white through the pinon and ponderosa, and the Gila Wilderness butts up against the western edge of the route.
This is a short but legitimately demanding run — the shelf sections require a high-clearance vehicle and careful driving, especially for anything over about 20 feet in length. Trailers and long-wheelbase rigs should stay home. The road is impassable in snow and can wash out in monsoon season; call the Glenwood Ranger District before heading up July through September. No fuel between Glenwood and Silver City. Camping is available in Gila National Forest below town. No permit required, but the drive demands respect and a spotter if you’re running wide.

Frequently asked questions
Can a full-size truck handle this trail, or is short wheelbase really required?
Short wheelbase is strongly preferred. The shelf road sections have tight switchbacks and exposed edges where a long-wheelbase truck or large SUV will struggle badly — think extended-cab minimum, crew cab at your own risk. Stock 4WD with high clearance works, but lockers or a limited-slip rear will save you on the loose rocky climbs.
When is this trail closed or impassable?
Winter closures are common after snowfall — the trail sits near 7,000 ft at Mogollon and stays icy well into spring. Monsoon season (July–September) turns the dirt sections into grease and can make water crossings dangerous. Stick to April–June or October–November for the best shot at dry, stable conditions.
Do I need a permit to drive this trail or camp overnight?
No permit required for the trail itself — it runs through Gila National Forest and dispersed camping is allowed under standard NF rules (typically 14-day stay limit, 300 ft from water sources and trails). No fee to enter. Check with the Wilderness Ranger District in Glenwood if you're planning anything near the Gila Wilderness boundary.
What's the hardest section and what should I actually be ready for?
The climb out of the Gila River basin on the Sandy Road stretch is where it gets real — loose rock, steep grade, and tight shelf road with no guardrails and significant exposure. One bad line on a wet day and you're having a very different kind of adventure. Airing down, patience, and a spotter on the gnarlier switchbacks are not optional on this one.
There's zero cell service — how far is the nearest fuel and what should I know about water crossings?
Fuel up in Glenwood, NM before you leave — there's nothing on this route and the nearest reliable gas after is a real drive. Water crossings of Silver Creek are present and depth varies by season; early spring snowmelt can push them higher than they look. Carry at least a day's worth of drinking water since stream water needs treatment and there are no developed sources on route.
