France's cities and larger towns have world-class public-transport systems. There are métros (underground subway systems) in Paris, Lyon, Marseille, Lille and Toulouse and ultramodern light-rail lines (tramways) in cities such as Bordeaux, Grenoble, Lille, Lyon, Nancy, Nantes, Nice, Reims, Rouen and Strasbourg, as well as parts of greater Paris.
In addition to a billet à l'unité (single ticket), you can purchase a carnet (booklet or bunch) of 10 tickets or a pass journée (all-day pass).
Driving is the simplest way to get around France but a car is a liability in traffic-plagued, parking-starved city centres, and petrol bills and autoroute (dual carriageway/divided highway) tolls add up.
France is famous for its excellent public-transport network, which serves everywhere bar some very rural areas. The state-owned Société Nationale des Chemins de Fer Français (SNCF) takes care of almost all land transport between départements (counties). Transport within départements is handled by a combination of short-haul trains, SNCF buses and local bus companies.
