Hey @Andris My favorite areas are the flow trail in Crockett, and anywhere on the Mt. Tam Watershed! Not all of it is truly single track, but it's all fun to ride and tends to be mostly single or double track! Do you have any favorite single track trails in the area?
Oh, nice! Haven't heard about Crockett before you mentioned it. Googled it and it looks like a great place to check out!
I currently don't have a favorite trail yet since I just got a propper mountian bike and looking to explore. I used to ride a while ago when I lived in CO, but been bikeless for few years.
Thanks for the suggestion @REI-LizH !
