The monks of Saint-Claude are credited with establishing a monastery in the 6th century to the southwest of the Abbey Lake on the island known as sur la Motte. Then, probably having fallen into disuse for several centuries, a second monastery succeeded it in the 12th century (1172) built to the northeast of the lake on the current site of the hamlet of l'Abbaye by the canons of the Abbey of Abondance (Augustinians of Haute-Savoie). The status of abbey, served by a particular abbot, remained for a century, until the monastery was the subject of an exchange of goods between the abbot of Abondance and that of Saint-Claude. Once again dependent on the Abbey of Saint-Claude, the Abbey of Grandvaux regained the status of priory. From the fortified buildings of the 12th century, which were accessed by a drawbridge, there remains today an old farm building (called La Joséphine after the former owner of the place), a presbytery and a church, dedicated to Notre-Dame de la Nativité, like that of Abondance. The site has been listed since September 15, 1966. A site to discover through a stroll in 4 scenes, evoking the history of the site.

The tour of the lakes is not of much interest, mainly being wide paths, without much relief, and with no view worthy of the name, including on the lakes (which we see very little, except on the eastern part, which is a shame). The western part is even difficult (we follow the road for 2km...). In short, a walk to forget, except perhaps for a running outing, or a detour via the Eagle peak.
