Worth knowing about San Francisco
- Sprint, Verizon, AT&T and T-Mobile turned on their networks inside BART's Transbay Tube in 2009, giving a continuous mobile signal from Balboa Park through downtown San Francisco, the Tube and the Oakland underground.
- BART says cell coverage and app functionality are still limited at some underground stations, especially when crowded, with the improvement project due to reach all stations by fall 2027.
- BART trains leave from the SFO International Terminal and reach downtown San Francisco in about 30 minutes; the AirTrain Red Line links the BART station to Terminals 1, 2 and 3.
- Oakland's airport, about 19 km east of San Francisco, connects to the BART network by the elevated BART to OAK connector, roughly a nine-minute ride to Coliseum station.
- Oakland's airport was officially renamed Oakland San Francisco Bay Airport, so an arrival ticketed as OAK is not the same airport as SFO.
- Since 10 December 2025, BART fare gates and the nearly two dozen Bay Area agencies using Clipper accept Tap and Ride: a contactless credit or debit card, Apple Pay or Google Pay, with no Clipper card needed.
- BART asks riders to take the Clipper card or bank card out of a wallet or purse before tapping, so the gate reads only one. Children aged 4 and under ride free.
- Muni riders must keep proof of payment for the whole trip, whether a ticket or pass, the Muni app or a Clipper card, or risk a fare ticket. Since December 2025 Muni readers also take a contactless credit or debit card for an adult single fare, tapped at the start of each trip.
- #SFWiFi, the city's free network in certain parks and plazas, was extended to Chinatown in 2025, covering Grant Avenue from Pacific Avenue to Broadway plus Dragon Gate and St. Mary's Square.
- Muir Woods National Monument has no cell phone service, and every personal vehicle and shuttle rider needs a reservation, so book it before driving north across the Golden Gate.
- Alcatraz ferries leave from Pier 33, and a ticket is the only way onto the island. The fare includes the cellhouse audio tour in eleven languages, and the Park Service suggests allowing a couple of hours there.
- Bay Area bridges collect tolls electronically with no cash lanes, and the Golden Gate charges only southbound into the city. Visitors and rental drivers not enrolled in a toll plan can open a Short-Term License Plate Account covering the past 48 hours or 30 days ahead.
