• No ticket or booking: walk in during store hours and head straight up to the roof
• Closes in rain or strong wind, so check the weather before making the trip
• Quietest on weekday mornings, while summer Saturday afternoons and the hour before sunset draw the biggest crowds

La Terrasse is the open-air roof on the 8th floor of the Galeries Lafayette Haussmann department store, directly above its Art Nouveau glass dome. From the top, kids can pick out the Eiffel Tower and the white Sacré-Cœur on the Montmartre hill across a sea of gray rooftops.

In the warmer months pop-up bars and restaurants set up on the terrace, and in winter an ice rink opens there.
