Getting there and around
Airports
Charles de Gaulle international airport is 27km (17mi) north of Paris. It's s a major transport hub, so you shouldn't have any trouble finding a flight, regardless of where you're flying. Flights run daily to all parts of the country, but the high-speed TGV (train à grande vitesse) train services are usually more convenient. Departure tax is built into the ticket price and varies according to the destination. There are lots of ways from Charles de Gaulle to the city, from shuttle trains to an assortment of public buses, private shuttles and taxis.
The city's second main airport, Aéroport d'Orly, is 16km (10mi) south of central Paris. A bus runs between d'Orly and Charles de Gaulle.
Beauvais is a smaller airport that handles Ryanair and charter flights.
Public transport
Say what you will about driving around Paris, but the city's public transportation is world class. The most charming of Paris' public transport options, the underground Métropolitain (and its sister system, the RER), is a simply massive network. No matter where you are, chances are there's a metro station within a few blocks.
Paris public transport is operated by the RATP and includes the métro subway system, RER trains, buses, night buses, Montmartrobus, and the Montmartre funicular railway, all of which accept the same tickets and passes. You can purchase individual tickets, booklets of ten tickets, or a Paris Visite Metro Pass designed for visitors and offering unlimited travel.
