“A steep and technical OHV alternative to Switzerland trail.”
— Alan Doak
Pennsylvania Gulch is a steep and technical alternative to the southern half of the Switzerland trail. Or, use this trail to make of loop of the southern half.
The upper section is mild dirt road (please observe side spurs that are posted no trespassing). The lower section, however, is steep, loose and rocky OHV road. I can't recommend this trail in the uphill direction, but the downhill direction is a good exercise in keeping it together.
Halfway down, give your brake rotors a chance to cool off by checking out the abandoned mine ruins.
