Public transport in Lisbon is inexpensive and useful for negotiating the hills between attractions. The fastest way to get around is by metro, which covers most of the city. Complementing this is a network of trams, buses, funiculars and a vertical elevator to connect the high and low areas of the city. There is also a modern electric train that links the city to all the towns along the Portuguese Riviera, and ferries across the Tagus River.Trams and buses are inexpensive and the old trams have become a big tourist attraction. It is best to avoid public transport during rush hours though, as the crowded conditions are the perfect cover for pick pockets. Metered taxis are plentiful and affordable, and a popular means of transportation, but beware of drivers taking long, indirect routes. A car is not recommended for use around the city.
