La Harmoye walks

A relaxing walk around the dam lake. The path along the banks is beautifully maintained. The artificial reservoir was created by building a dam at the end of the 19th century to supply the Canal de Nantes à Brest during periods of water shortage. A gauge shows that the water level at the dam can reach 14 metres.

In the footsteps of the Toileux: 19th-century linen manufacturers; a journey back in time with the Cromlec'h de Lorette (an ancient covered burial passage) ending with the Rigole d'Hilvern: a man-made stream dug to feed the Nantes-Brest Canal - a little-known aspect of Brittany.

One of the most beautiful walks in the department, passing through the Bois des Mauriers and the Chaos du Gouët. A mixed walk, a third on roads, the rest on paths and trails. The route is well signposted in yellow on posts. The route can be tricky after heavy rain. Firstly, there is the charm of the names of the paths and trails indicated on the signs. Then there is the vegetation and its variety, as you cross the departmental forest: the Bois des Mauriers. Finally, there are the Chaos du Gouët, a spectacular pile of rocks on the Rivière du Gouët, which you skirt around.

This hike was completed and written during the summer of 2015, an exceptional period when the lake was drained for dam maintenance.We invite hikers to do this walk in spring, when the colours and scents are at their best, with the clear waters of the lake as a backdrop. Since 2024, major work has been underway between points 3 and 4 with a view to building a free Himalayan footbridge for crossing the Blavet, which cuts the complete tour of the lake in two. This will still be possible for the most experienced walkers. (See note in "Practical information".

Starting from the Mileade centre, this hike will take you along Lake Guerlédan to the dam. On the way back, you can take a break at the leisure centre before crossing the Bois Cornec.

This hike will take you to Porz Braz along the Anse de Landroanec, then the Bois de Caurel. You will pass the prehistoric camp of Castel Finans before going back up through the woods and returning to Porz Braz.

The second part of the tour of Lake Guerlédan, the most physically demanding, particularly at the start. Departure from Le Manet towards Anse de Sordan, passing by the former Abbey of Notre-Dame de Bon Repos. Return route via the western side of the lake.

Between the Côtes-d'Armor and Morbihan. Following the Guerlédan trail, you climb up to overlook the dam built around 1930 to supply the region with electricity, then through heathland and woods, you descend to the Nantes–Brest Canal. As you pass through the village of Saint-Aignan, you’ll come past an interesting little church and the electricity museum. Also worth seeing on the way out of the village is the small Saint-Aignan dam.

Historically dedicated to Marc Faucon (a pioneer of hiking in the Côtes d'Armor), this hike will allow nature lovers to explore the foothills of the Gouët and the wooded hills of the surrounding countryside.

A beautiful route that initially follows the edge of Lake Guerlédan via theGR® 341, then climbs up to the Butte de Malvran, which overlooks the surrounding area.

A superb hike taking place largely through woodland, with magnificent views of the lake from the highest points. Some sections of the trail are quite steep, ideal for a good leg workout, but over short distances. Walking poles may be useful for those less confident on their feet. There are numerous lodges and campsites available for overnight stays. There are seven different starting points; check the lake’s website http://www.lacdeguerledan.com/ for details. The trail is very well signposted with “Sentier de Guerlédan” markers throughout the route and the red and white markings ofthe GR® 341 andGR® 37. A few paths branch off the main trail to stay close to the lake or climb a little higher into the forest, but always rejoin the main trail. Please note! The entire route around the lake is open from 1 March to 15 September. Outside this period, sections of the trail are closed for hunting.

First section of the tour around Lake Guerlédan, Brittany’s largest lake. Departure from Anse de Sordan towards Le Mané, passing by the Guerlédan dam. This route follows the eastern shore of the lake.

A lovely hike that allows you to discover the shores of Lake Guerlédan. Start at Anse de Sordan and walk back up to Bon Repos Abbey.

A walk almost entirely in the forest with sections along sunken paths. This route leads to a disused quarry that is now a pond (see photo).

The Bois d'Avaugour and Meur offer a mix of gravel tracks and footpaths. The Tro Vras route follows the western circular loop, featuring beautiful paths through heathland, along the Avaugour (which reveals its beauty in winter, when the vegetation clears) and forest tracks. The transition to the eastern circular loop is challenging (with mud in winter) but offers sections passing by some very beautiful trees. The eastern circular loop, pleasant at the start, is less interesting on the return leg, except for the last three kilometres of descent, initially amongst tree stumps in a fir forest.

This hike will take you through the Rigole d'Hilvern on good paths. In the Middle Ages, according to legend, Saint-Caradec belonged to the Viscounty of Rohan. A smallpox epidemic occurred between 1865 and 1870, claiming 45 lives. Then, in 1902, a typhoid fever epidemic broke out in the region.

A short circular walk to discover the covered alleys listed as Historic Monuments, then the Daoulas Gorges in a somewhat wild rocky environment. A complete change of scenery guaranteed. As a bonus, and for a short 1 km detour, I suggest you visit the ruins of Notre-Dame de Bon Repos Abbey.

Take a short loop around Bon Repos Abbey by following the towpath of the Nantes-Brest canal to the Bellevue lock. The hike continues on theGR®34trail, which runs along the shores of Lake Guerlédan before venturing into the countryside and returning to the abbey.
