How to get from CDG airport to Eiffel Tower? We are arriving on a Wednesday and leaving on Sunday. Should we buy a week pass?
Navigo Decouverte Week Pass is perfect. You can buy Navigo at CDG from either T1 or T2 train station ticket offices.
Route from CDG to Eiffel Tower would be RER B to Denfert Rochereau, transfer to Metro 6 direction Charles de Gaulle Etoile until Bir Hakeim station, this is as close as you can get to Eiffel Tower.
