Another great way to see the sights is the tram and Tram 28 is the one to take to discover Alfama which is the medieval part of Lisbon. Alfama is picturesque and hosts lots of interesting sites. Tram 28 costs €2.85 pp one way and a good place to hop on is Praça Luis de Camões. In peak season the tram can get very full with limited seating so if you walk up from Praça Luis de Camões on a street called Calcada do Combro, you may have a better chance of getting a seat and a good view of Lisbon. Please beware of pick pockets on Tram 28, you have been warned.
