Visiting San Francisco
A hilly, compact city on the water, known for the Golden Gate Bridge, cable cars, and a famously mild but changeable microclimate. Its neighbourhoods can each feel like a different city block by block, from Victorian houses to steep, view-filled hills.
Best time to visit: September to November, when fog is less frequent and temperatures are at their warmest — summer here can be surprisingly cool and foggy.
Landmarks & highlights
- Golden Gate Bridge
The Art Deco suspension bridge that has defined the city's skyline since 1937.
- Alcatraz Island
A former federal prison on an island in the bay, reachable by ferry and best booked ahead.
- Fisherman's Wharf
A lively waterfront area with seafood, sea lions, and views across the bay.
- Golden Gate Park
A large park stretching from downtown to the ocean, home to gardens, museums, and open lawns.
Local tip: Bring layers even in summer — Mark Twain's famous (if apocryphal) line about a cold San Francisco summer is closer to true than visitors expect.
Getting around: The city's steep hills make walking tiring in places, but cable cars, buses, and the Muni Metro cover most routes well.
Good to know: Alcatraz tickets regularly sell out days or weeks ahead in peak season — book as early as your dates are confirmed.
