More difficult shortcut off Switzerland Trail.

Shortcut route from town of Sunset to Highway 72. Usually done by drivers looking for a bit more challenge as diversion from Switzerland Trail, Trail #32. Views limited to looking back down the narrow canyon. Surprisingly, this is a county road, shown on maps as C.R. 95J. We found no markings on the route. Unlicensed vehicles use the route, but technically they are not allowed on a county road. Enforcement is always possible by the county sheriff, but this seems unlikely based on past history. Nonetheless, we do not show this road as open to unlicensed vehicles. Travel at your own risk. Open all year.


Trail Ratings Defined

We couldn’t bring ourselves to rate this road difficult, although a few places come close to this rating. It’s rocky and steep, but has no major obstacles. It’s a very narrow shelf road for most of its length, with very few places to pass an oncoming vehicle. We recommend the trail be driven uphill because uphill traffic always has the right-of-way. If you drive it downhill, you may have to back up a considerable distance to let someone get by.

Trail was dry at the time I ran it. Lots of washouts in areas. Erosion in the Trail is making it more difficult over time. Didn’t have any major issues getting through. 2019 JLU Sahara with a 2″ lift and 35s

Some very deep drifts in the narrow sections. Made it going uphill. Along with another rig. Made a recovery just beyond the wide spot at the top. Someone out for a Sunday drive on street tires & temporary tags. Not recommended. They had no idea what they were about to get into, had they not gotten stuck where they did. Got them out and turned around and back to Hwy 72, safely.

This trail has become a solidly difficult rating, as erosion has only made it rockier. There’s barely any mud/dirt left and our lifted zj on 33″ tires barely made it through, and we had to use a bypass on a part that would have sent us onto our side.

We’ve changed the rating on this trail from moderate to difficult due to excessive erosion in the last few years.


Rate this trail on a scale of 1 to 5.

8/17/2019 Pennsylvania Gulch was a fun ride today. Conditions were dry and traction was not an issue. I ran it in the uphill direction. I did not engage my lockers or air down my tires. Most of it is a good moderate trail, but there are a few parts I would rate as difficult but not expert/heavily modified required. My Jeep is a 4dr rubicon with a small lift and 35” tires. I believe a stock 4dr on 33” tires could manage fine.
