Highlight: Tomichi Pass
Tomichi Pass is a high-mountain trail connecting Brittle Silver Basin to the north with the mining town of Whitepine to the south. This trail is often compared to many of the routes in the San Juan Mountains as the north side of the trail is almost fully visible from the start as it cuts across talus slopes under the red mineral deposits of Brittle Silver Mountain. Don't let the beautiful scenery fool you because this is a difficult hard-core trail not for the faint of heart. The shelf road in Brittle Silver Basin is extremely narrow and off-camber in places and is prone to rockslides, as you will see in Waypoint 3. Driving experience and modified vehicles are highly recommended.

Directions to Trailhead

Starting Point: Hancock Pass

The Tomichi Pass Trail begins at Waypoint 7 of Hancock Pass. To reach this point from Pitkin, you must drive the Alpine Tunnel West and then continue on to Hancock Pass. To reach the start of Tomichi Pass from Buena Vista, you must drive the Alpine Tunnel East Trail and then continue to Hancock Pass. To run the trail in reverse, you will start at the town of Sargents. From Sargents, travel east on Highway 50 for a short distance and turn north on County Road 888. Continue north on 888 through the town of Whitepine and to the start of the trail at the Tomichi Cemetary. Follow the waypoints in reverse.



Land Use Issues

Tomichi Pass has suffered from intermittent rockslide issues on the Pitkin Side for many years and has been threatened with permanent closure. In 2019 CORE, the trail adopter was able to reopen the pass after a 3-year closure due to a major rockslide. Many volunteer hours are spent each year maintaining the road over the rockslide area to keep the pass open to the public.
