The walk takes place in Paris in the 16th arrondissement on the old railroad line of the small belt.
The "petite ceinture" was a railroad track that went around Paris. It was gradually abandoned, the last trains ran until 1985 and then the tracks were removed in 1993. The City of Paris decided to rehabilitate some sections into forest trails open to the public. There are other sections of the old "petite ceinture" open to the public: la promenade plantée dans le 12ème and la petite ceinture dans le 15ème. Unquestionably it is in the 12th district that the walk is the most beautiful because it overlooks the city while passing on a viaduct. The walk in the 16th district is of little interest.
