Cycling is a popular option for tourists on a budget, with bike racks on Muni buses and many wanting to cycling across the Golden Gate Bridge, though the steep hills can be a struggle.
Ferries are a popular choice for those wanted to check out Alcatraz and Golden Gate from the waters; Alcatraz cruises offer ferries to and from the prison every half hour but book a time slot online in advanced as these book up quick. Blue and gold fleet ferries is a great choice to take in a different perspective of San Fran.
Some may wish to rent a car whilst in San Francisco but be aware that parking is difficult and expensive; especially in downtown SF; plus you should check with your hotel if they have parking availability.
If you are a UK citizen, remember to bring both parts of your driving license and check the rental companies policy on international rentals. Buses and cable cars can get you around the city, although rather slow in rush hour.
We found the city sightseeing bus a great option to get across SF, with routes serving Golden Gate Bridge, downtown SF and across the piers.
Taxis are a good choice to catch the early morning Alcatraz cruise or after a late night out, fares start at £3.50 and $2.75 for every mile.
