Sonora Pass is located near Pinecrest, Tuolumne County, California, USA. It is off of Highway about 60 mi/96.5 km east of Sonora.
In Tuolumne County, along Highway 108, snowmobiling is a big attraction. At the end of the plowed portion of Highway 108, 6 mi/9.6 km beyond Strawberry is the Sno-Park, a favorite launching point for snowmobile lovers.
Sno-Parks are parking areas, that are maintained in the winter, so people can park safely and experience their winter activities, such as snowmobiling. In order to use a Sno-Park, you must have permit. A route on the Tuolumne Side is Herring Creek, a 26 mi/41.8 km, round trip, leading out of the Herring Creek road.
The first 8.5 mi/13.7 km, just before the Y that lead to Herring Creek Reservoir are fairly tame. After that, the road makes a 13 mi/21 km loop. Attention is required, because the road passes through some steep slopes, that are very vulnerable to avalanche after fresh snowfall.
You should check with the Forest Service, before deciding to take this route. Another route is Long Barn to Hull Creek, a 10 mile road, starting from Long Barn and leading to Hull Creek and when snow conditions are safe, it can be extremely exhilarating.
