While metro is, with its three lines, the quickest and most efficient way to move around Budapest don’t miss its yellow trams that will not only trasfer you efficiently from point A to point B but also allow you to see the street scenes along the route. Budapest trams are yellow and quite old, so they swing while riding the curvy tracks giving you the feel of some past times, but also showing how the tram system can be simple and efficient even in the 21st century.
Tram lines #4 and 6 ride along the first ring road and connect the Moszkva ter via the Margaret bridge with the Nyugati station, Oktogon, Blaha Lujza ter and further southwards along the Ferenc Jozsef street. The line no. 2 and 2A are usually cosidered the best if you want nice views of the Danube, the Castle hill and Gellert hill as it passes along the eastern embankments of the river. If you go to the public transport website their “welcome note” will read: “Did you know that you enter into a contractual relation with our company when you get on our vehicle to travel?” Make sure you have a valid ticket, since there are many controllers checking the “contractual relation”!
