Trail Overview

Go from Sunset, CO to Highway 72 on this fun route. If you want to make a loop, use the first portion of the Switzerland Trail. This will also offer a bit more challenge. The upper portion of the trail goes through a small residential area. It is open all year. Check weather first.

Difficulty

Difficult. One section is washed out with deep ruts, exposed tree roots and large, loose rocks. Very narrow shelf road for most of its length, with very few places to pass an oncoming vehicle. Please keep in mind that this is a county road and could be graded at any time. In past years, the road has been left in its natural state.

2005 Jeep Grand Cherokee

Only was able to get halfway up the trail until it started going up hill and the bigger rocks were covered in a sheet of ice almost making it impossible to get over but also a very nice trail

Ran west to east (downhill). Dry, narrow in places but not too many challenging obstacles. Might be more challenging east to west. Id suspect itd be very tough if wet/mud/snow.

Not too difficult for this mostly stock RZR pro w/30” tires. One P.U truck passed us heading east (downhill direction of loop). Was dry conditions today. challenging mainly due to being so narrow and eroded. Not many large rocks to crawl over though.

Access Description

The most direct way to reach the start of this trail is to leave Boulder on Highway 119 and turn right on Fourmile Canyon Road 118. Follow this road to town of Sunset and turn left on C.R. 93. Go to first switchback, less than 0.2 mile, to trail on right.
