I live in the "bay area" up in Sonoma County. There is tons of stuff to do up here. I live 15 minutes from a redwood forest and 45 minutes from the coast, which has good bouldering. Mount St. Helena is 45 minutes in the other direction, with great top-roping.
I actually don't know much about the south bay or east bay, but the north bay has tons of good outdoor possibilities.
