Culture & Daily Life
📜 History & Origins
The Yelamu Ohlone people inhabited the San Francisco peninsula for thousands of years before Spanish settlers established the Presidio of San Francisco on 29 June 1776, alongside the nearby Mission San Francisco de Asís. The city was incorporated under US control in 1850 following the Mexican-American War. The 1848 California Gold Rush transformed it within two years from a town of 800 into a city of 25,000, establishing its role as the West Coast's primary commercial centre.

🎒 Visitor Tip
Buy a Clipper card for Muni buses and trams, BART metro, and the cable cars (which the card makes slightly cheaper). The city is only 7 by 7 miles — many neighbourhoods are walkable but the hills can be brutal. The Golden Gate Bridge is best walked east-to-west for the best city views. Book the Alcatraz ferry well in advance — it consistently sells out 2-3 weeks ahead.

Surface area and physical characteristics
A hilly peninsula bounded by the Pacific Ocean to the west, San Francisco Bay to the east, and the Golden Gate strait to the north. The city has around 50 hills, with Twin Peaks reaching 282m being the highest accessible summit. The terrain drops steeply toward both coasts. Built on a mix of bedrock and landfill; parts of the city — including the Marina District — are on reclaimed bay mud, which is vulnerable in earthquakes.
