With a marked geography, this urban valley offers many panoramas. Dotted with pavilions and gardens, the hillsides reveal a strong presence of nature. The aqueducts, elements of a vast water supply network of Paris, are the monuments. The river, along which the first villages settled, was buried 50 years ago and is now the subject of a reopening project. Guided by a landscaper, the course will start in front of the Jean Macé elementary school in Arcueil, to end on the banks of the Bièvre in Cachan.
Attention: due to the topography of the site, this route is not accessible to people with reduced mobility.
