See bottom of article for info on passes.

Metro 

The metro in Lisbon is the quickest way to travel and there are 4 main lines all coming to the city centre. Head for Baixa-Chiado or Restauradores stations for the old and historical parts of the city centre. There is also interesting architecture and tilework in the stations, so is an attraction in itself. Beware however of pickpockets. Written and audio warnings in both Portuguese and English can be found in most stations but this will not protect you of theft attempts. More information about the rapidly changing and expanding network can be found on the Metropolitano de Lisboa website. This is a useful website as you will be able to obtain more detailed maps around each station with bus and tram routes included. A day pass costing 4.60 Euros can be obtained from the stations and will allow travel on the cities' buses, trams, funiculars and metro for 24 hours. Note that the ticekt costs an extra 50 cents but can recharged - don't throw it away!

Buses, Trams & Funiculars

There is an extensive network of buses, trams and funiculars in Lisbon, and they are all worth a ride on, especially the vintage trams, and the funiculars. They are an attraction in themselves. The network is constantly changing and more information can be found on the Carris website.

There is a very good unofficial map of the four remaining tram routes at  http://www.urbanrail.net/eu/pt/lisboa...

Here is the official map on the Carris website. Also look at individual bus lines (which includes the trams) for the stops along the line. Carris' network map is more oriented to Lisboans than visitors but can be useful if also looking at a good city map.

See the article on Tram 28 in the "Things to Do" attractions section. It is a very popular way to see the old district on the hill where Castelo do Sao Jorge is located.

Fares and Passes

Flat fare on the buses is €1,75 - cash paid on board. Flat fare on the trams (streetcars) is now 2,85 Euros with the object being to make more users buy pre-pay passes. However the cost of these increases yet again on 1st February 2012; new prices given below.

There are a variety of passes available which reduce those costs considerably. Details are available in English on the Carris website as above. (Unfortunately the Carris website is difficult to navigate and is lacking in information.)

The "best deal" for a visitor is to buy the Viva Viagem unlimited pass for as many days as required. The cost is 5.50 euros for the first day, and 5.00 euros for each additional day. It is good for all buses, trams and Metro. It allows unlimited use throughout the city. It can be purchased at any Metro station and in some post office branches. It is best to see the attendant in the booth rather than try to use the automated ticket vending machines as they are confusing and apparently do not take all credit cards. Do note that buying at the booth requires cash.
