San Francisco International Airport (SFO) is the main airport serving San Francisco. Golden Gate Bridge lies about 17.3 miles from SFO, and the best way to reach this destination without a car is via the Bay Area Rapid Transit (BART) and line 28 bus, which takes 1 hour. However, if you appreciate comfort and convenience, then a self-drive in a rental car is handy. Still, if you have extra funds to spare, hail a taxi.
