The Graca Circle

Route 12 Remodelado tram 577 on Rua Sao Tome at the junction with Graca Circle line 28

Probably the most famous tram route in Lisbon is the Graca Circle. The Graca Circle line is made up of two separate routes, the 12 and 28, both of which wind their way up from the city centre through the hilly Alfama district, before diverging and descending to meet up again at Praca Martim Moniz. These lines are like a twisting switchback, and are some of the steepest adhesion only tram routes in the world. Route 28 is the most popular of these two services with tourists, with the trams often running to capacity all day through the Alfama district. A shorter but equally hilly journey through Alfama can be made on the circular route 12, where the chance of finding a seat is much easier.
