Everyone knows the Petite Ceinture, that 32-kilometer-long former railway line that circles Paris. Although trains haven’t run on it for years, the railway right-of-way has given way to a rich and well-preserved ecosystem. Some parts of the Petite Ceinture, well known to walkers, are very pleasant. But others remain wild or closed to the public.That was the case with this tunnel, located in the 15th arrondissement. Closed for decades, this nearly 300-meter tunnel has now been completely restored, much to the delight of all walkers.
A walk stretching over 2 km along the Petite Ceinture in the 15th
Opened this month, this section of the Petite Ceinture, located around Georges-Brassens Park, offers a new playground for all lovers of urban walks. This opening now ensures continuity between the Balard/Olivier de Serres section to the west and the Dantzig/Brancion section to the east.

News that’s dividing residents! While some are delighted to be able to explore new sections of the Petite Ceinture that were previously inaccessible, others are concerned about the lack of safety inside the tunnel, calling it a “danger zone,” especially after dark…
The 15th arrondissement’s Petite Ceinture now allows urban explorers to walk a little over 2 km in one go! It’s another reason to marvel at one of the most unique and surprising spots in Paris.
