3 (0=Paved, 6=Very Difficult 4WD)
2WD easy dirt road to 10,100' at the main Mt. Massive TH. Then, narrow Easy 4WD to 10,500' at the N. Halfmoon Creek TH.
From U.S. 24 just south of Leadville, turn onto Colorado 300. Drive 0.7 mile, turn left onto County Road 11 and continue another 1.2 miles before turning right onto the Halfmoon Creek road. Reset your trip odometer and follow the Halfmoon Creek dirt road for 5.3 miles to reach the Mt. Massive parking area on the right. The road above this point becomes more difficult so low-clearance or 2WD vehicles should definitely park at the Mt. Massive trailhead. Continue to 7.3 miles and keep straight at a junction. Now the road gets more difficult, requiring 4WD with good clearance. Overcome the last 0.5 mile to reach the small, marked trailhead on the right. There's parking for about 8-10 vehicles at or near the trailhead.
Usually closed just a short distance up from where the road changes to dirt - over 8 miles below the TH.
