Overview

The Cimarron Ridge Trail climbs from the Middle Fork Cimarron drainage to one of the highest ridge walks in the Uncompahgre Wilderness. The 11.4-mile round trip is a demanding alpine day with sustained elevation and an off-trail ridge traverse that rewards navigation-confident hikers with complete solitude and expansive views.

The Uncompahgre National Forest sees far fewer visitors than its neighbors (Ouray, Telluride, Crested Butte) despite comparable scenery. The Cimarron drainage is one of the least-known access points into the high country.

The Route

Miles 0 to 3: Valley climb. The trail follows Middle Fork Cimarron Creek through spruce-fir forest and into open willows, gaining steadily. Elk are frequently seen in the meadows in early morning.

Miles 3 to 5: Treeline transition. The trail passes treeline near 11,500 feet and enters alpine tundra. Wildflowers are dense in the tundra meadows in late July.

Miles 5 to 5.7: Ridge traverse. The maintained trail ends near the wilderness boundary. Navigation on tundra and talus leads to the high point of the ridge. Views encompass the Cimarron peaks, Wetterhorn, Uncompahgre Peak, and on clear days the La Plata Mountains to the south.

When to Visit

July through September. Snow covers the ridge into early July most years. September is quieter and offers stable weather, though early storms are possible after mid-September.

Practical Details

The access road (FR-860) requires high-clearance vehicles and is not recommended for standard passenger cars. No facilities at the trailhead. Carry all water you need for the ridge traverse. The dispersed camping guide covers Uncompahgre Wilderness camping rules.

Leave No Trace

This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.

Safety Considerations

The strenuous rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Uncompahgre National Forest and may be unreliable in canyon bottoms or remote terrain.

Trailhead Parking

Middle Fork Cimarron Trailhead on FR-860. High-clearance vehicle required. Space for 10-12 vehicles at a primitive pullout.
