We planned to follow California Highway One from the SFO Bay to Santa Monica and back. This two lane highway clings to the state’s western edge and offers views of some of the best landscapes in California. Winding north from Sausalito through Marin, Sonoma and Mendocino Counties, the road follows the coastal contours, rising and falling, zig-zagging around coves and curving around hillsides slopes that drop dramatically to the sea.
