Vintage tram cars dating from 1908 to 1924 trundle along a special route, starting at the Public Transport Museum and going via stops at Prague Castle, Malostranské náměstí, the National Theatre, Wenceslas Square, náměstí Republiky and Štefánikův, with most finishing at Výstaviště. You can get on and off at any stop, and buy tickets on board (ordinary public transport tickets and passes are not valid).
