Start by meeting the host near the tower. The host will provide your tickets, assist with security checks, and guide you to the second floor. From there, view landmarks like the Arc de Triomphe, Notre Dame, and Sacré Cœur.
On your way down, visit the first floor to see the glass floor and a small Eiffel Tower museum. There is no time limit, so take your time exploring and taking photos around the tower after your visit.
