I will be traveling to Versailles for a day trip from Paris.
My hotel is near the Arc de Triomphe, so I will be starting at the Charles de Gaulle Etoile Station. I will take Line 6 to the Eiffel Tower. This is where my question is. It looks like the Eiffel Tower has two stops: Champ de Mars and Bir-Hakeim. Which station will Line 6 drop me off at? And which is the correct station for the RER C? Can you get between both without exiting the system?
Thanks!
