Seven by seven miles of hills, Victorian houses and bay views, San Francisco packs more personality per block than almost any American city. Ride a cable car, wander Chinatown and North Beach, and walk the bridge when the fog pulls back.

Locals know the secret: summer is often foggy and cool, while September and October deliver the city's warmest days.
