For a great view of the city – one that includes the Eiffel Tower so you can look back at your pictures and recognize it’s Paris, go up the Tour Montparnasse. The elevator takes you up to the 56th floor in 38 seconds (so fast!) and then you can head up to the open-air terrace on the 59th floor. It was amazing – and slightly more thrilling when it’s super duper windy.
Confession: I didn’t get much of the views as I was just trying to not fly away. (That sounds more dangerous than it actually is. There is a sheltered glass-wall walkway that lines the entire perimeter of the terrace so you can’t actually fly away/fall off.)
Tip: Montparnasse Tower is part of the Paris Pass. Admission is included.
