Any tips for avoiding the lines at Eiffel Tower in Paris? Can you bring up a backpack?
Besides having a reservation at a restaurant, is there any other ways to aviod the lines at the Eiffel Tower? Maybe time of the day or something else.
Also, can you bring a backpack or small bag with you?
Start early or go with a group. Groups get special handling, that is to say, they go really to the head of the line.
They do have security checkpoint before you get on the elevator, so let that guide you.
