Overview
The South San Juan Wilderness is the most remote wilderness area in Rio Grande National Forest, covering 158,790 acres of high volcanic terrain along the southern boundary of the San Juan Mountains. The Continental Divide runs through it, providing the long-distance spine that the CDT follows south toward New Mexico. The 10-mile out-and-back from Stunner Pass provides a demanding sample of this terrain without requiring multi-day logistics.
The route climbs from the Stunner Pass area to the divide itself, where the views open across the San Luis Valley to the Sangre de Cristo Mountains to the east and south into the forested highlands of northern New Mexico. The South San Juan Wilderness is genuinely quiet, no day-use fees, no permit requirements (as of 2026), and no infrastructure. What it offers is the kind of backcountry solitude that Colorado's more famous wilderness areas can no longer provide reliably.
Rio Grande National Forest manages this wilderness through the Divide Ranger District. The Creede office is the practical contact for current trail conditions, access road status, and any permit updates.
The Route
Miles 0 to 2.5: Stunner Pass to Wilderness Boundary
The trail climbs from the Stunner Pass area through mixed conifer forest toward the wilderness boundary. The terrain is open enough in sections to provide early views back toward the Conejos Valley to the south. The wilderness boundary is reached at approximately mile 2.5. The CDT junction is signed.
Miles 2.5 to 4.5: CDT to Divide
Following the CDT north, the trail climbs steadily toward the Continental Divide. The forest thins and the terrain opens to alpine tundra as the divide approaches. The views expand in all directions as elevation increases. Small streams provide water in the lower portions of this section.
Miles 4.5 to 5.0: High Divide
The trail reaches the Continental Divide at approximately 12,200-12,400 feet. The standard turnaround is at the high point of the route on the divide ridge. The views from here are expansive: the San Luis Valley, the Sangre de Cristo Mountains, and the volcanic highlands of the South San Juans extending to the north and west.
When to Visit
July through September. Snow can persist on the upper route into July. Early September often provides the most stable conditions and the best chance of clear views. The remote location and lack of maintained facilities make preparedness more important here than on more popular trails.
Afternoon thunderstorms are common in July and August. The exposed divide ridge is a serious lightning risk. Plan to be off the high terrain before noon when storms are developing. Check conditions before your trip.
What to Bring
Many hikers carry:
- 3 liters of water (with filter for stream refills below the divide)
- Full shelter system for the exposed alpine terrain
- Paper map and compass in addition to digital navigation
- Emergency shelter given the remote location
Consider bringing:
- Bear canister for overnight trips
- Detailed topo map for the wilderness interior
Practical Details
No facilities at the trailhead or on the route. Cell service is absent. Pack out all waste. Free campfire permits required for overnight camping. Review Leave No Trace principles for wilderness ethics.
For overnight trips, see how to get a national forest camping permit. Bear canister requirements provides context on food storage in Colorado wilderness.
Getting There
From Creede, take CO-149 south and then Forest Road 250 south toward Stunner Pass. The road is rough gravel and high-clearance is recommended. Consult the Divide Ranger District in Del Norte for current road conditions and specific trailhead directions before your trip. The remoteness of this trailhead means that road conditions directly affect access feasibility.
