3 (0=Paved, 6=Very Difficult 4WD)
The road is a bit rocky but no large rocks. The biggest deterrent to smaller vehicles is a creek crossing to get to the trailhead proper. Compact, short wheelbase 4WD vehicles can drive an additional .75 miles up Forest Service Road 889 to the beginning of the trail itself. Long wheelbase vehicles are strongly discouraged from continuing up FS 889. The trailhead parking area has a couple of campsites and is otherwise very small, so try not to take up too much space if you can.
Measuring from the intersection of US 550 and Ouray County Road 361 (also known as Camp Bird Road) just south of Ouray, drive 7.3 miles south on US 550 and turn left onto Ouray County Road 20. Follow Ouray CR 20 0.4 miles, following the sign for Brown Mountain and crossing Gray Copper Creek, and the signed Gray Copper Trailhead will be on your right.
