The best way to travel the Cote d'Azur is by train. Local trains (TER) are efficient, comfortable and normally on time. Prices are reasonable, for example: Cannes to Frejus (old Roman town) return costs 6.10€ and 4.60€ for the over 60's. Nice is 4.90€ (3.70€) and Ventimiglia in Italy is 10.50€(7.90€)
Between June and September the Carte Isabelle ticket allows you to travel all day for just 12€ on any line in the Alpes-Maritimes and Vintimiglia in first or second class. This ticket can also be used on the scenic Roya Valley railway from Nice to Tende. All tickets are available at Cannes station from the ticket counter or machines (see right) and if you are very clever go to the French Railways site.
Mind you if you think the TGV is fast have a look at what was achieved in 1953 in England. SEE FILM
