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 for Eider Creek. Continue along the dirt road another 1.0 mile to the Mill Creek TH which is just before a couple sewage ponds. There is very limited parking here along the road and one small pullout. The trail is on the north side of the road. This trail is considered a "short-cut" to the Deep Creek Trail and will also intersect the "Sneffels Highline Trail."
