Getting to & from the train station by KB&MC
If you arrive in Nice at the main train station, you can get to the Old Town or surrounds quite easily by the tram for 1 euro. Again, there are peak times when it is full, but it is an easy and relatively fast way to get about. Sometimes the wait can be more than 15 minutes, in which case you miught be better off walking.Buy your ticket beforehand - at most stops - and validate it onboard. Easy.
Taxis are horrendously expensive in Nice.
