Shuttle busses drive from the Charles de Gaulle airport to;  Etoile, Porte Maillot, Gare de Lyon and Gare Montparnasse between the hours of 5.45am and 11pm. Tickets cost around €7. Taking a taxi is the less favourable option, as it will take longer and you will pay a lot more to get into town, around €38 and €43, depending on your exact destination.
