Paris subway - Metro map

Subway in Paris is the most efficient (and the cheapest) way to go from a point to another... 14 lines serve the city. If you stay for 2 or 3 days and plan to visit many monuments and attractions pay for a pass... If not buy 10 tickets (10,7 Euros). The city center is quite safe and very few problems have been reported even in the subway.  The first Metro trains run at around 5:30am; the last one runs at 1:00am - After 1.00am take Night buses that run regularly on a limited number of routes from central Paris (chatelet) to the outer areas - Central Paris is rather small (about 10km in diameter) and distances between one Metro stop to another are rarely more than a 5-10 minute walk! Remember that walking through Paris streets is the best way to indulge yourself in the city. The RATP web site offers an excellent tool (in English or French) to assist in planning your route(s) throughout Paris and its suburbs
