For either a driving approach on CO145 from Lizard Head Pass or CO62/CO145 Placervlle, follow CO145 2.0 miles west from the CO145 junction referred to by many as "Society Turn/Junction." You'll be following the segment of CO145 that leads into Telluride. At 2.0 miles, turn north (left) onto FR637, a graded dirt road. Follow that road .75 mile to a switchback with some limited parking. This is the trailhead.
The land around the trailhead is largely private property. We do not recommend attempting to camp there. There are no facilities. There is no camping available in this immediate area unless you pack in for a ways. At-large camping anywhere near Telluride is difficult to come by and generally not allowed. The nearest campground is located along HWY145 about 5 miles south from "Society Junction." That's the "Sunshine" Campground and it is Forest Service maintained with fee. You may be able to find some at-large spots on 63J south of Illium or back along HWY145 before climbing the big hill into the Telluride Valley. There are several at-large spots along the highway, but be careful of private property. There is also a campground located on the east end of the town at the town park. Campsites are available on a first-come-first-served basis. These links offer more information:
