Yesterday I made my way back to this great spot in Napa for a ride. The trails here are maintained as well as any spot I’ve ridden in Marin. If you like Camp Tamarancho, you will certainly enjoy the Skyline Wilderness Park.
Didn’t capture a lot of footage but did get a little when I had a view. This should give you a flavor for the higher terrain:
There are many technical sections you will encounter here and all but a couple can be cleaned with the right line, gear selection and of course speed. There are climbs but none last too long and the payoff is there as it should be.
I found this spot through one of my goto bay area ride websites for rides.
