The modern (Métro Léger) tram system has five routes running to various parts of the city. The useful lines are 1 for the southern bus and louage stations, 2 for consulates on Ave de la Liberté, and 3 and 4 for the northern bus and louage stations. Line 4 also has a stop for the Bardo Museum. The main stations are Place Barcelone and Place de la République. Tram fares are usually around US$1.
The TGM rail system connects central Tunis with the northern beachside suburbs of La Goulette, Carthage, Sidi Bou Said and La Marsa (US$1, 5am to midnight).
Private taxis are cheap. It’s hard to run up a fare of more than US$15. A short hop will cost less than US$3, and a longer one, such as to the Bardo Museum, around US$4.
