Subject: Re: CDG/Paris using the RER
Hi Jane, The St. Michel station serves both the Metro as well as the RER train, perhaps that is the confusion. You'll simply enter the St. Michel station, follow the signs to the RER train--line B, if I remember correctly--buy your ticket and take the appropriate train to CDG. You'll need to leave the RER station at CDG and take the free shuttle bus (called a navette in French)over to the international airline terminal to catch your flight. The shuttle circles constantly so you won't have too long to wait. Since CDG is confusing you might want to stop at an information counter and ask specifically where the shuttle bus picks up passengers. Hope this helps.
