The Doubs river runs alongside the cliff (climbing site) where archaeological remains from the Paleolithic, Neolithic and Bronze Age were found in a cavity known as the "trou de la mère Clochette".
From the top of the cliff you can admire a beautiful panorama of the Doubs valley and the Chaux forest massif. At the top, a small chapel dedicated to Notre Dame de la Consolation is the remnant of an ancient hermitage. A little legend tells the story of a young girl pursued by soldiers who threw herself off the cliff and survived, hence the other name of the site "le saut de la pucelle".
A little further down are the remains of the fortifications of Rochefort sur Nenon dating from the 13th and 14th centuries, consisting of a tower and a fortified gate.
Many small houses, originally fishermen's huts, line the river between Rochefort sur Nenon and Audelange.
