This trail can be run in either direction, and it's a great trail for doing some sightseeing. It is suitable for all SUVs and 4x4 vehicles.
If you start at the south end, you will run the first part of the Sugarloaf Mountain trail until you get to the trailhead and turn for Switzerland Trail. It is a fairly well-defined right turn off of the Sugarloaf Mountain trail at a parking area. The trail starts going north, then quickly turns west. The trailhead for hiking up to Sugarloaf Mountain is also here.
Follow the main road, forest service road 327. There are a few rocky sections, but nothing technical. If you stay on the widest trail you are on the correct trail. Other spurs can get difficult, and they will always continue up or downhill off of Switzerland Trail.
When you get to the tiny town of Sunset, continue through to the other side to turn right on Road 89. The trail is flat and easy, following an old railroad bed.
Soon you arrive at the Mount Alto picnic area, marked with a sign. You can see the remnants of a pavilion that once stood here and functioned as a stop along the railway. It is a great place for lunch.
Continue north to County Road 52. Turn right here to go to Gold Hill, or left to Highway 72.
