1. Eiffel Tower — Champ de Mars, 7th
The highest view in Paris, from the summit or the second floor.
The Eiffel Tower has two viewing levels plus the summit. The second floor gives the best balance of height and detail, with monuments still recognizable; the summit gives the widest panorama.
Book timed tickets online and go at sunset to see the city in daylight and lights.
Good to know: Take the stairs to the second floor for a cheaper ticket and shorter lines.
