サン＝セーヌ＝ラバイエのおすすめウォーキング＆ハイキングルート

A bucolic, clean, well-maintained, and shaded spot, with tables and trash cans for picnicking. It's officially a Paris commune, but it looks nothing like Paris.

Be careful when going down the 10 meters of the small path to see the chasm. Even in dry weather it is slippery and there is nothing to prevent you from falling into the chasm. So be careful.

The Creux Percé is an inverted cone-shaped collapsed chasm approximately 60 m deep and with a circumference ranging from 35 to 25 m at the surface. This chasm is primarily known to speleologists. Exploration of this chasm and its lateral networks began in the 19th century. This site has long been a natural icehouse with a bottom that reaches sub-zero temperatures, even in summer. https://www.bourgogne-tourisme.com/ In May 2025, a special outing, supervised by the Dijon Speleo Club, will allow visitors to descend into this crater.

There's a signposted and very beautiful circular trail that includes the source of the Seine. Learn more on the official website here: https://www.cotedor-randonnee.com/

Of the three caves, two are relatively easy to access. One can even be walked through—a beautiful place.

The Celerons viewpoint is accessible via a narrow path that branches off from the hiking trail. Caution! The path runs right along the edge of the cliffs. However, the view over the Combe des Vaux des Roches gorge and its foothills is fantastic and worth the short detour.

Wikipedia reports: "The source of the Seine is located on the Langres plateau, 25 km northwest of Dijon in the Côte-d'Or department in the Bourgogne-Franche-Comté region, 470 m above sea level. A special feature is that the sources of the Seine were the property of the city of Paris from 1864 onwards. An artificial grotto was built a year later to protect the main source and a statue of a nymph was erected to symbolize the river. Paris has since returned the property to the region. Near the source are the remains of a Gallo-Roman temple in which a Dea Sequana (Latin goddess of the Seine) was worshipped. The archaeological finds from this temple are now in the archaeological department of the Musée des Beaux-Arts in Dijon."
