Transport
In Nice
For Nice itself a car can be a hindrance. Parking is not easy and not practical especially in Vieux Nice. If you are fit, cycle, using a Vélo Bleu, or just walk. Failing that there is a good and cheap Ligne d'Azur bus service and also the modern tramway which goes from from the North west of the city to the north east via the Place Masséna in the centre. Taxis can be expensive.
Outside Nice
If you intend to explore the Côte d’Azur either side of Nice then either use the bus or the train.
A car is useful but expect very heavy traffic especially east of Nice and parking can be difficult. However, while there is a bus service into Nice Beyond and the Parc National du Mercantour, the best method of exploring this region is by car.
There is an excellent train service into the eastern side of the Parc National du Mercantour – the Train des Merveilles leaves Nice in the morning and returns during the afternoon.
Please Note: While the Ligne d'Azur bus service in Nice and along the Coast is generally very reliable, it tends to stop operating during the early evening.
