The Carbon Trail #436 begins on Gunnison County Road 12 and ends at Forest Service Road 730.1B. After crossing Coal Creek, the trail begins to climb and intersects the Green Lake Trail #566 in about 1.8 miles. Continue straight to stay on the Carbon Trail, however a nice downhill is available by turning east and following the Green Lake Trail back to Crested Butte. The Carbon Trail can be fairly rocky and loose as you ascend to an elevation of 10,600 feet. After about 5.1 miles it turns west and begins its descent and comes to an end at FSR 730.1B after another 3.7 miles. Geo-Ref Trail Map Geo-Reference Instructions
