Mysterious, alluring San Francisco is a constantly shifting kaleidoscope of moods and sensations. Even the weather has a life of its own, with warm summery days in the fall, and wintry days in the summer months. Fog flows like a mist over this crucible of peoples and ideas, transmuting all into new forms. It has repaired itself after fires and earthquakes, taken in waves of immigrants, and hosted the psychedelic Summer of Love, accepting differences with humor and equanimity. With all its innovation and vision, the city reveres and preserves its past. The Victorian houses, cable cars, and the spirit of its Gold Rush days are alive today. The city is ever-changing, yet serene, with a civic minded, tolerant populace. It is no wonder that it is one of the most beloved travel destinations in the world.
