Fourmile Creek Trailhead

Mosquito Range

Road Difficulty

2 2WD, rough dirt, good clearance

Location

12,000 feet
39.20575, -106.1622

Driving Directions

From Fairplay, drive just over a mile south on U.S. 285 and turn right onto County Road 18. Drive 10 miles and pass the Leavick site, at 11,250'. Continue another 2 miles to reach the trailhead at a gate and small parking area. The road becomes a bit more rough as you approach the end, but it's usually ok for most SUVs and good clearance vehicles. If this upper lot is full, you will see it as you approach and can park in one of the pull-offs lower down the road.

Notes

Rough 2WD dirt to the TH. In early summer, the upper portions of the road may require 4WD/AWD.

Most Recent Update 10/17/2026:

A silver car is stuck in the snow on the way up. We made it in my jeep to the gate. Some slightly icy and slick spots but was doable with 4WD. When we got back from the summit there were only a few other vehicles, a tacoma, 4 runner and another jeep. The rest parked a little ways down.
