Airport Shuttles and Ground Transport

• Travel passes for public or mass transportation offers a good deal and can save you some money.
• Trains are often cheaper than shorter flights and/or for getting to and from an airport.
  
  In Paris, both the regional network trains to City centre and the TGV (Trains de Grande Vitesse - High Speed Trains) leave directly from Charles de Gaulle airport.

• Using shuttles are a good way to share cab-fares if you're traveling alone
• Taxis are convenient but rarely worth the price. If you do hire a taxi, consider asking someone to split the fare with you.
