Trail Overview
Switzerland Trail
It is amazing to consider what it must have been like to be on a train winding down the steep terrain on this trail. The scenery is fantastic, especially in the fall. If you want a longer adventure, continue north. Trail is open all year.
In 1883, a railroad was built to the town of Sunset. It was later extended to the town of Ward and followed roughly the same path as the road you follow up the north side. It made a stop at the Mt. Alto Pavilion, now just a picnic area. Later, in 1905, the railroad was extended south from Sunset to reach Eldora, a thriving mining town at the time. A flood in 1919 washed out most of the track.
