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.

For museum lovers, the San Francisco Bay Area is the place to be. For art, visit the De Young Art Museum to see art ranging from 17th century to contemporary, the San Francisco Museum of Modern Art for 20th century works, and the Asian Art Museum to see their expansive collection of Asian art. If science and engineering are more your speed, check out the activities at the Exploratorium, the interactive nature exhibits at the Randall Museum, or learn about the history of transportation at the Cable Car Museum. Cap off a busy day of culture and exploration with fresh sushi and karaoke in Japantown!
