Just north of San Francisco, the Marin Headlands offer panoramic views of the Golden Gate. As you cross the Richmond-San Rafael Bridge, the bay's blue waters give way to the brown hills of the North Bay.

In Sonoma County (just west of Napa), the small town of Sonoma has the historic Sonoma Plaza, California's largest town square. The plaza is surrounded by boutique wine shops and delis. For lunch, try the Sonoma Cheese Factory for a picnic.
