San Diego has some of the best riding in the country, but the Bay Area is different and special. California all-around. My riding included: excursions around the chaparral of Mt. Diablo; up the Oakland/Berkeley hills via Broadway Terrace and Grizzly Peak; up to the east peak of Mt. Tamalpias via the wonderful old railroad grade; and through grasslands and redwoods on a 25 mile loop around Pescadero and San Gregorio.
Mt Diablo holds an enormous array of fire-road possibilities. I explored only the trails around Shell Ridge and the Briones-Mt. Diablo trail:
