Tram lines 4 and 6 follow almost exactly the same route along a semicircular path along Budapest’s Grand Boulevard, only diverging for one or two stops in south Buda; tram line 6 operates around the clock. Linking Buda and Pest across Petőfi Bridge and Margaret Bridge, along their paths, the streetcars traverse several Budapest zones, including Districts II, VI, VII, VIII, IX, and XI, providing many hop-on-hop-off points along the way.
