What makes San Francisco unique
San Francisco grew from a small Spanish mission and fort, founded in 1776, into a Gold Rush boomtown after 1849, when prospectors and the businesses that supplied them turned a village into a major port city. A 1906 earthquake and the fire that followed destroyed most of the city, and the rebuilding that followed produced Coit Tower, the civic centre and the 1915 Panama-Pacific Exposition that showcased the new San Francisco. The Golden Gate and Bay Bridges rose during the 1930s, and cable cars, once common across American cities, still run here as working transport rather than a museum piece.
Neighbourhoods to know
Union Square and the Financial District anchor downtown shopping and business; North Beach and Chinatown sit just north, the city's Italian and Chinese quarters. Fisherman's Wharf and Ghirardelli Square line the northern waterfront, while Russian Hill and Nob Hill climb steeply behind them with cable car lines and panoramic views. West of downtown, Haight-Ashbury keeps its 1960s counterculture streets, the Castro remains a historic centre of the city's LGBTQ community, and Golden Gate Park runs nearly to the Pacific shoreline.
When to go and how long to stay
Late September and October bring San Francisco's warmest, driest weather, after summer's coastal fog has mostly burned off. The National Park Service's San Francisco Maritime park warns that the city can turn foggy and windy at any time of year, so warm layers are worth packing in any month. Three to four days cover downtown, the waterfront and Golden Gate Park at an easy pace, with longer stays leaving room for Alcatraz, whose ferries are best booked well ahead, and day trips north across the bridge.
Getting around
Downtown, North Beach, Chinatown and Fisherman's Wharf form a walkable but hilly core, and three cable car lines, run by the SFMTA, connect Powell Street to Fisherman's Wharf and Nob Hill. Muni's buses, trains and the historic F-line streetcars reach the rest of the city, while BART links downtown to the airport and the wider Bay Area. Many hills are steep enough that a bus, streetcar or cable car beats walking, even over a short distance. The Golden Gate Bridge opened in 1937 and its east sidewalk costs nothing to walk, which keeps it on every shortlist of top attractions in the United States.
