Trail Overview
Dusy/Ershim Trail
If you want extreme off-roading, this is a great choice. The trail is long and impressive. It follows a wide corridor through a large wilderness area. It is open to ATVs, UTVs and dirt bikes. Please stay on the trail, and obtain a fire permit before visiting.
You can't talk about this trail without talking about the Four Wheel Drive Club of Fresno. They pioneered and built this trail starting in 1956 one section at a time starting on the north end. The final section between Dusy Meadow and Thompson Lake was broken through in 1968. In all, they built 10 trails in the Shaver Lake area, most of which are in this book. A big thanks to the club for their efforts. For details go to www.4wdcfresno.net.
