Before you go

Entry and visas

Citizens of Visa Waiver Program countries, including the UK, most of the EU and Qatar, need an approved ESTA, which costs $40 since 30 September 2025; apply at least 72 hours before travel on the official CBP site. Others, including Indian, Saudi and Emirati citizens, need a visitor visa, and appointment waits can be long.

From the airport

San Francisco International Airport (SFO) is 30 minutes from downtown by BART train.

Getting around

Muni buses, streetcars and cable cars plus BART; pay with the Clipper card or a phone wallet. Walking the hills is steep but rewarding.

Local tips

  • Pack layers: summer fog makes July cooler than September.
  • Never leave anything visible in a parked car; break-ins are common.
  • Book Alcatraz tickets only through the official operator.
  • Some downtown blocks feel unsafe at night; use a ride-hailing app.

Areas worth knowing
