You can download the pdf chart of the bus and streetcar network (8MB). You can get a paper copy at the lignes d'azur offices.
Please note :
- the 98 and 99 lines have a special fare and can be used only with the AERO ticket.
- the 94 line goes to Vence and is not meant for passengers who want to travel within Nice. In the Nice-Vence direction you can board the bus anywhere but you won't be allowed to get off in Nice. (First get off stop at the "Passerelle", in St laurent du Var.) In the other direction the driver will not let anyone board the bus when it is in Nice, after the Var River. DO NOT USE THE 94 buses to go to the airport if you come from Nice. It stops in front of the terminal 1 but you won't be allowed to get off. See here what you have to do to go to the airport. use the lines 52, 59, 70, 23 or the special lines 98 et 99.
The rules about line 94 are also valid for the Conseil General bus lines : 200 to Cannes, 400 to Vence and 500 to Grasse.
You'll find the lines timetables in the Lignes d'Azur offices or on their website.
You can also use this free app, available for Iphone or Androïd. It claims to be able to produce itineraries but they often are very weird. It works well, however, to give you the timetables, in spite of a user-unfriendly interface.
