Hey,
So i live in Oakland CA and spend some time up in Napa/Sonoma area, does anyone know any goods spots to ride that are kinda close to the bay area?

 

There are a number of places to ride in the area, all require a bit of driving. The State OHV parks: Hollister Hills and Carnegie are nearby. San Jose County Park is on the way to Hollister. Going north there are a number of areas to ride in National Forests.

Here is a link that has quite a few riding areas.
