Switzerland Trail Description

Overview

The Switzerland Trail in the peaks west of Boulder was named for the spectacular mountain scenery along this remote and former railroad route. The trail is popular with mountain bikers, ATVs, and 4X4s, and may not be considered rideable for hybrid bikes.

About the Route

Leaving off from the south end of the trail, the route leaves from below the summit of Sugarloaf Mountain off the road of the same name. From here it winds along a relatively level grade, gradually descending to Fourmile Canyon Drive (US 118), along Fourmile Creek. Here it crosses the road and begins a gradual ascent back up the mountain on its way toward Gold Hill. The Switzerland Trail's northern end is at Sawmill Road (County 95) just above Lefthand Canyon Drive.

The elevation on the trail gently fluctuates between around 7,700ft and 8,700ft. The mountain itself has peaks that rise to 9,000ft.

Trail History

The relative level grade of the trail owes its existence to an old narrow-gauge rail line around the turn of the 20th century. The line was built to accommodate mining operations in Colorado's front range, and the trail route itself is listed on the National Register of Historic Places as the Denver, Boulder, and Western Railway Historic District.

 

Parking and Trail Access

The Switzerland Trail runs between Sawmill Rd. (Jamestown) and Sugarloaf Mountain Rd. (Boulder), where parking is available.

Parking is also available along Gold Mill Rd.

Switzerland Trail Reviews

Not a trail for gravel bikes. Rugged and rutty from the Sugarloaf Rd. Trailhead. Mountain bikes can handle it but double track with plenty of ATV traffic.

Fell in love with this trail !!!

We went in a four wheel jeep and very glad we did. The view is absolutely breathtaking and surreal. Wasn't a busy trail at all. Must go and Dont forget the camera

Great trail for a 4 wheelers start

No big obstacles and not a hard trail at all. It can be hard to follow the trail. But just stay on the most traveled road and you should be fine. Can be done in a stock vehicle, there was a Subaru on the trail with us.

Labor Day weekend ride

First five miles from south trail head about an 800' climb over rocky and sandy terrain mixed with dirt bike and ATV traffic. The slog uphill pretty worth it to get to better graded road and nice downhill section over next few miles. Turned around about mile 8 but will go back to ride full route. Not much other bike or hike traffic which was pretty sweet.
