Budapest’s oldest mode of transport, the tram, is a lot like the bus in that you can get across the city quickly and efficiently while enjoying the views. The tickets work in conjunction with the metro and bus, making it easy to use all three together. There are more than thirty lines running on the main radial and riverside routes on both sides of the Danube and several of the bridges. At the tram you have to validate your ticket by using the punching machines as you board. Don’t forget to push a button next to the door if you want to get off.
