1. Empire State Building — Midtown, Manhattan
The Art Deco tower that still defines the New York skyline, with an open-air deck on the 86th floor.
Completed in 1931, the Empire State Building is the city's most recognizable skyscraper. The visit starts with an interactive museum on the building's history before elevators carry you to the 86th-floor observatory, which wraps around the tower in the open air.
An upgraded ticket adds the 102nd floor, with floor-to-ceiling windows. The restored Art Deco lobby on Fifth Avenue is worth a look on its own.
Good to know: Go after dark: the observatory stays open late, the lines are usually shorter and the lit-up city is spectacular.
