France's cities and larger towns have world-class public-transport systems. There are métros (underground subway systems) in Paris, Lille, Lyon, Marseille, Toulouse and Rennes, and tramways in cities such as Bordeaux, Grenoble, Lille, Lyon, Nancy, Nantes, Nice, Reims, Rouen and Strasbourg.
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.
