Explore San Francisco
San Francisco has many nicknames—the Golden City, Paris of the West, and The City That Knows How are just a few. This coastal hub for arts and culture draws visitors every year for its varied cuisines, numerous museums, and stunning natural landmarks. From San Francisco’s Haight-Ashbury and the Castro to Sonoma wine country and Silicon Valley, the San Francisco Bay area has something for everyone.
After landing, downtown San Francisco is merely a hop, skip, and a jump from the airport with public bus, rapid rail, and commuter rail transport options. Once you’re in the city, take a ride around on the historic cable cars, or try driving down Lombard Street’s famously sharp curves. You can’t miss a visit to the Golden Gate Bridge, whether you decide to walk across to neighboring Sausalito or simply enjoy a picnic with a view in Golden Gate Park.
