Trailhead: Rock Creek TH Stats: 13.5 Miles, 2,050' Elevation, 8 Hours 1 Minute
Trailhead Directions: From I70, head north on CO-9 7.6 miles to Co Rd 1350. Turn left (west) on 1350 and head 2 miles to the winter trailhead on the left. Turn left here and continue all the way up (1.2 miles) to the summer trailhead. The road is rough, recommend high clearance. (Although someone managed to drive their Camaro up there...so...whatever.)
