“A great downhill from Gold Lake to Jamestown and a hike-a-bike for the last mile.”— Charles S
Note that the last mile of County Road #102J was ravaged by the flood of 2013, which completely ripped the road and trail out. The trail now requires a good deal of hike-a-bike on the last mile over log bridge crossings and the beginnings of the newly generated trail.
If you are heading downhill from Gold Lake, once you reach the juncture with FS Road 509.1 (Flying Squirrel), County Road #102J has a creek crossing that can be ridden in low water, but otherwise be ready for a creek bike portage. From here down, the trail is rougher and interrupted by the incredible power of the 2013 flood. Due to this flood damage, the trail hardly sees much traffic.
Lots of wildlife viewing potential on this trail: moose, beaver, elk, deer, and mountain lion have all been reported.
