Overview of San Francisco
Flights to San Francisco land beside the bay, at the edge of a compact city of hills, fog, cable cars and some of the best food on the West Coast.
The city itself is small enough to cross quickly, and it is the natural starting point for wine country, the redwoods and the coast road south.
