A highlight of any visit to Lisbon is a ride on the number 28 tram. This enjoyable tram route passes through many of Lisbon’s finest districts, including Baixa, Graça, Alfama and Estrela, but most visitors travel on it to climb the steep hill from Baixa to the castle and Alfama. Due to the undulating route, only the classic Remodelado trams, which were originally commissioned in the 1930s, are able navigate the steep inclines or sharp twists of the tracks. These trams (that would be in a museum in any other city) are an integral part of Lisbon public transport network, and a ride on the number 28 tram is a highlight of any trip to Lisbon.
