Forest, lake and architectural history shape the discoveries around Saint-Aignan. There are also hikes of varying lengths and difficulty, as well as chapels and church art. When planning your visit, it’s worth weighing up a trip to the water, a walk and the cultural and historical sights.
Forest and water around Saint-Aignan
The Forêt de Quénécan covers around 4,000 hectares, 900 of which lie within the municipality of Saint-Aignan. The creation of Lac de Guerlédan also visibly changed the landscape: the lake was formed during construction of the hydroelectric power station between 1923 and 1930. The Blavet, the Canal de Nantes à Brest and 17 locks were flooded in the process, between Saint-Aignan to the east and Nicholo Lock to the west.
Anse de Sordan is the only easily accessible point on the southern shore of Lac de Guerlédan. Its gently sloping shore is suitable for launching small boats. The beach offers opportunities for swimming, other water sports and fishing; numerous woodland walks along the lake shore also invite you to get active. Swimming conditions and facilities may vary by season. Check local conditions when planning a stay by the water.
Hikes with different route profiles
The purple Hent Glaz Circuit is a 4 km hike to Chapelle Sainte-Tréphine, the lake and the dam. For a longer route, there are two options of different lengths: the easy Circuit du Blavet is 12.7 km long and takes about three hours. At 13.0 km, the Circuit du barrage de Guerlédan is slightly longer, is rated difficult and takes around four hours. It can be explored on foot, on horseback or by mountain bike.
The shorter Hent Glaz brings together three of the sights mentioned on a 4 km hike; the two longer routes differ not only in length but also in difficulty rating and permitted activities. This lets you choose according to your preferred distance and activity, without assuming that all the routes offer the same kind of outing. Local trail conditions can change; seasonal restrictions may also apply to the Circuit du barrage de Guerlédan. Check conditions before setting out.
You can reach Chapelle Sainte-Tréphine from the upper dam car park via a 300 m footpath. The Neo-Gothic chapel dates from 1897. Its history and location offer a different way to explore the area’s cultural heritage from the hikes by the lake.
Church art, hydroelectric power and tradition
The nave and transept of Église paroissiale Saint-Aignan date from the 15th century. In the north transept, an altarpiece depicts the Tree of Jesse with numerous figures in high relief. The church offers a close look at religious art; Chapelle Sainte-Tréphine complements this part of your visit with a Neo-Gothic building from the 19th century.
The Électrothèque du lac de Guerlédan explores the history of electricity and the construction of the hydroelectric power station. It also offers workshops, guided tours and activities for families and children; programme details may vary by season. This is a chance to explore the area’s technological history alongside the lakeside landscape.
Another cultural option is the Pardon de Sainte-Tréphine, celebrated every year in May. The procession leads to the Neo-Gothic Fontaine Saint-Trémeur. If you’d like to plan your stay around this festival, check the latest programme in advance.
