The Parc de l’Observatoire is a park in Meudon near Paris. It owes its name to the astronomical observatory nearby. After leaving the park, I walked towards the Seine and the Parc de Saint-Cloud.
The “Ballon de Paris” is a large helium-filled balloon located in the Parc André Citroën, near the Seine in southwest Paris. It has sensors for monitoring pollution but also takes passengers: The balloon goes up to 150m and stays there for a few minutes before going down. The view is quite nice even if it is not centrally located.
Issy-les-Moulineaux is a suburb south-west of Paris, on the left bank of the Seine. Many large companies have their French headquarters there.
During the summer, I went to Paris for 1 day. I just walked around, starting at Gare de Lyon. The city was as grimy as ever, although the sun showed up in the afternoon.
