You only have to pay if you want to visit the interior of the Arc de Triomphe, its museum and its terrace. Between the two columns of the Arc de Triomphe is the tomb of the unknown soldier with the eternal flame rekindled every evening.
Do I need to book tickets in advance for Eiffel Tower?
You can book your visit up to two months in advance: and we definitely recommend booking for the summer months (July and August), when the Eiffel Tower is at its busiest. For visits on a whim, our online ticket office sells e-tickets for a visit the same day (while stocks last) within 30 minutes before your visit time.
Do I need to book Paris museums in advance?
We recommend booking at least a week in advance as the morning time slots available for pass holders often book out a few days in advance. If you make a reservation for entry with the Paris Museum Pass, you will need to bring both your proof of reservation and a valid Paris Museum Pass to enter the museum.
