Alder Creek Road to Frog Lake via Crabtree Canyon

Gravel route from Alder Creek Rd to Frog Lake Rd, Truckee, Nevada County, California

"Frog Lake was opened to the general public during 2020. There are several private properties in the area, but this specific route is permitted as far as I know, with no signs to the contrary. It's all dirt roads with a couple of quite steep sections. I used 35mm all-round tyres on a gravel bike (and no punctures) but 38mm or larger would have made it easier "
