Top Things to Do in San Francisco
Golden Gate Bridge
San Francisco's most iconic landmark. Walk or bike across the 2.7km Art Deco bridge, then continue to the charming town of Sausalito on the other side. Photo spots: Battery Spencer and Crissy Field.
Alcatraz Island
The infamous former federal prison, now a fascinating national park accessible by ferry. The audio tour featuring former inmates and guards is one of the best in any historic site. Book tickets well ahead.
Fisherman's Wharf & Pier 39
Sea lions, sourdough bread bowls and clam chowder — quintessentially San Francisco. Also the launch point for Alcatraz tours and Bay cruises. Touristy but worth it.
Cable Cars & Lombard Street
Ride the historic Powell-Hyde or Powell-Mason cable car lines — the only moving National Historic Landmarks. Get off near Lombard Street to see the famously crooked one-block descent.
Napa & Sonoma Wine Country
90 minutes north of the city — California's most famous wine region. Hire a driver or book a guided tour to taste at world-class wineries like Domaine Carneros, Castello di Amorosa or Inglenook.
Chinatown & North Beach
The largest Chinatown outside Asia, packed with dim sum spots and unique shops. North Beach next door is San Francisco's Italian quarter — head to City Lights bookstore and Caffe Trieste.
When to Fly to San Francisco
January and February typically offer the cheapest fares — and surprisingly, the weather is mild (12–16°C). The famously foggy San Francisco summer (June–August) is also peak tourist season with the highest prices. September–October is the warmest, sunniest time (also called 'Indian Summer'). Avoid Thanksgiving week, Christmas and New Year for fares.
San Francisco's Airport
SFO
San Francisco International Airport
Located 21km south of downtown San Francisco. The BART train connects directly to Powell Street in about 30 minutes. SFO is United Airlines' hub and one of the busiest US airports for international travel.
OAK
Oakland International Airport
Located across the Bay, primarily used by domestic and budget carriers like Southwest. Connected to BART via Coliseum station. About 45 minutes to downtown San Francisco.
Getting Around San Francisco
San Francisco is one of America's most walkable cities. Pick up a Clipper card for unlimited rides on Muni buses, trams, BART subway and the iconic cable cars. Uber and Lyft both started here and are widely used. For trips outside the city (Napa, Yosemite, Big Sur), hire a car.
Before You Fly
- ESTA required: Australians need an ESTA (Electronic System for Travel Authorization) approved before flying. Apply online at esta.cbp.dhs.gov at least 72 hours before departure. Valid for 2 years and multiple entries.
- Tipping: Tipping is standard in the US — expect to tip 15–20% at restaurants, $1–2 per drink at bars, and a few dollars for housekeeping, valet and taxis.
- Layers: San Francisco weather is famously fickle. Bring layers — even summer evenings get cold from the bay fog. Mark Twain (apocryphally): "The coldest winter I ever spent was a summer in San Francisco."
- Travel Insurance: US medical costs are notoriously high. Comprehensive cover is essential.
