The best way to explore Florence is on foot: the city centre is
compact, and traffic is restricted. There is a comprehensive bus
network (ATAF) operating from 5.30am until midnight. Tickets are
valid for 90 minutes for a single-use ticket, or multiple-ride
tickets of two or four 90 minute-uses can be purchased. Tickets
must be validated by punching them in a machine when you board the
bus. Tickets, and various bus passes, are available from any vendor
displaying the ATAF sticker, such as newsagents, automatic
dispensers, coffee bars and on-board the bus.
Using taxis in Florence is difficult, as they cannot be hailed
on the street. Taxi ranks can be found outside the train station
and most tourist sites, or they can be phoned.
