Ticket options include riding the elevators to the very top (I recommend getting this option; select "Lift entrance ticket with access to the summit"), riding only as far as the second level, or climbing the stairs to the first or second level (the top can only be reached by elevator).
How do you get on the Eiffel Tower?
Eiffel Tower Entrances | Location and Getting ThereEntrance 1 of the Eiffel Tower is the one at the South Pillar. You will pass through a security check here. This entrance is for those who wish to take the stairs. One can buy tickets for the stairs up to the 2nd floor, or for the stair + lift to the top (blue flag).
