Situated somewhere between Mûr de Bretagne and Saint-Agnan, this splendid blue touch in the very heart of the Argoat is the quiet border between the Côtes d'Armor and Morbihan. While you gaze at the calm and glimmering surface of Guerlédan lake, you will find it hard to imagine that this perfect setting may not have been orchestrated by nature itself. It is however a totally artificial piece of work, whose construction goes back to the middle of the 20th. When the flood barrier was put into service in 1933 at the meeting point of the Blavet river and the canal from Nantes to Brest, the valley was flooded over 13 kilometers and several lock keepers' houses and gardens were swallowed up by the water. (but not the equivalent of the city of Ys, as it has sometimes been told!)

 An ideal destination for water sports and hiking
With its 400ha surface and 45 meters depth, Guerlédan lake is the biggest in Brittany. It offers a wide range of outdoor activities: water sports, recreation park, bathing and even some fitted out beaches, like the one in the cove of Sordan. The oak, beech and spruce trees of the Quénécan forest shed shadows over the shores, where hiking through genuine nature becomes a real pleasure while you discover sites like the “Saut de Chevreuil” and the gorges of Stand Er Ihruen. Don't leave out any of interior Brittany's secret charms and visit the peat bogs of Coron and Goarem-Tronioly, preserved sites because of their frailty and the wealth of the fauna and flora.

 Shores steeped in history
The undulating landscape, dug out by streams on their way to the canal from Nantes to Brest, offers a multitude of heath and moorlands, heaps of granitic rocks, and stony ridges. The top of the Linscuis heath offers a sumptuous view of this mythical waterway that dates back to the XIXth century. Bearing witness to an even farther past, an arrangement of megaliths goes back no less than 6000 years. Not far from there, going along the Blavet's banks, you will come across a superb Cistercian Abbey from the XIIth century, the Abbaye de Bon Repos. Art lovers should not miss the biennal event of contemporary art in the abbey: “Murmures”, since 2003,  is a meeting point for contemporary art and heritage, artists and the local population.
