Rocky Mountain National Park Visitor's Guide



Switzerland Trail

This popular mountain biking and 4WD route is an old railroad bed, so the grades are moderate.

Bikers, the surface is not technical, but it is rough and rocky. The stretch north of Gold Hill Road is less traveled because the connection at the north end at Sawmill Road requires a short, steep scree scramble with your bike on your shoulder where the new road fill covers the old railroad bed. The largest elevation drop is from either Gold Hill Road or Glacier Lake/County Road 120 to the junction of Sunset/Fourmile Canyon Drive. The Switzerland Trail can be made into a loop with a return by the Gold Hill Road an Peak-to-Peak Highway.

Drivers, much of this road is high clearance two-wheel drive, but it is one lane in places. It passes the Mount Alto Picnic Area. There are fine views to the east, and it is a good place for aspen colors in late September or early October.

Can be accessed from the Peak-to-Peak Highway (CO 72) at the southwest end, Fourmile Canyon at the low point from the east, Gold Hill Road or Sawmill Road near Lefthand Canyon on the northeast. In Boulder Ranger District, Roosevelt National Forest.
