What is the best way to get to the Eiffel tower from the train station? How long will it take?
Bus #42 go there for Gare du Nord.
Enter the Gare du Nord station [make sure you choose STATION as the type] and then enter Eiffel Tower [make sure you choose PLACE as the type]. The planner's down right now but I think it should be back up later today. Have fun !
