Paris: Easy Get Around

Compared to a lot of other cities in the world, Paris' public transportation system is really convenient, affordable and easy to understand. The first thing you should know is that there are two types of trains in Paris, the Metro and the RER. The metro is a subway system that covers central Paris, whereas the RER (Réseau Express Régional) is a commuter train system that covers much of the greater metropolitan area of Paris, such as the two Paris airports (Charles de Gaulle (CDG) & Paris Orly (ORY)), Disneyland Paris and Chaeteau Versailles. Paris fare zones apply to the RER train system, unlike the metro where each single journey always costs 1,70€.

If you're only sticking around in Paris, but travelling to several locations within Paris, I recommend getting a book of 10 tickets (carnet) that are sold at 13,70€ (1,37€ per ticket, saving 20%). These tickets are not restricted to time, so you can use it for anytime on any day until your tickets run out. This was what I opt for but there are many other alternatives such at the Ticket Mobilis (Paris Day tickets), Carte Paris Visite (Multi-Day Paris Metro Tickets), and Pass Navigo Découverte (Paris Metro Week Pass Card). Information for all of these passes can be found from Paris By Train. 

If you're ever lost, Paris metro signs are all over the place. But don't be afraid to ask the locals. Où est la station de métro la plus proche? (Where is the nearest metro?) Contrary to what people have said about the french, I found my experience with the french rather pleasant. More than once they have tried to help me read maps and give me directions. With all this information, you'll be around the streets of Paris with no lack of confidence.
