The Eiffel Tower is the rare icon that beats its own postcards, and timing is everything: ride up in the hour before sunset, watch the city turn gold from the summit, and be on the ground for the first after-dark sparkle. Booked right, it is the best two hours in Paris.
Book the summit lift online the moment dates open; the stairs-plus-lift ticket is the fallback that skips the longest queue. Security lines are shortest at opening and after 8pm.
Bir-Hakeim and Trocadéro are the classic métro approaches, Trocadéro for the reveal across the river. A Seine cruise leaves from the quay at its feet and makes the natural second act.
