Brennilis walks

A beautiful hike around Lake Saint-Michel, with views of the Monts d'Arrée, discovering the Yeun Elez peat bogs, menhirs and legends dear to the writer Anatole Le Braz.

On the border between Léon and Cornouaille, at the foot of the Roc'h mountain range (Roc'h Trédudon, Roc'h Trévézel), the iconic backbone of the Monts d'Arrée, La Feuillée, Brittany's highest village, is well worth a visit.

This hike takes you from the foot of the Monts d'Arrée to the ridge, which rises to 385 m, with superb panoramic views on both sides.

The walk is mainly in the Forest of Huelgoat, starting from Lake Huelgoat with little elevation gain. Points of interest: the Devil's Cave, the Virgin's Household, the Trembling Rock, the Red Bridge, Artus' Cave, the Menhir of the Boar Pond, the Boar Pond, the viewpoint, Artus' Camp.

Does the Rivière d'Argent (Silver River), which glitters beneath the canopy of trees, owe its name to its bright sparkle in the twilight, or is it the nuggets that have escaped from the old mine that give it such a luminous appearance? The walk, which follows the mine's supply channel and then the turbulent course of the river, may provide the answer. It appears that the route is no longer passable between points 4 and 6. If you venture there, please confirm this on the comments page.

In the heart of the Huelgoat Forest, this woodland setting hides a wealth of heritage treasures. The Mine Canal will take you to the old silver-lead mine and then on to the most iconic sites in this legendary forest.

Roc'h ar Feunteun, Roc'h Trédudon, Roc'h Trévézel, a line of jagged ridges. In the heart of the Armorique Regional Nature Park, the Monts d'Arrée rise up in a landscape of moors, heather and gorse. These landscapes give off a surprising impression, marked by unreality, mystery and authenticity, which we know well in inland Brittany.

Mountains in Brittany? It's possible. Despite their low altitude, the Monts d'Arrée offer a real mountain setting with rocks emerging from the moorland. This route along the mountain ridges will immerse you in a landscape of heather, gorse and rocky ridges similar to those found in Ireland or Wales. Please note: Since the fires of summer 2022, a municipal decree prohibits passage through the peat bog before the point (10). The circular is currently impossible.

Between the 16th and 18th centuries, thanks to linen weaving, Commana enjoyed a period of prosperity, which explains the richness of its parish enclosure. From the village, dominated by its 57-metre-high bell tower, the view stretches north to the Léon plateau and south to the ridges of the Monts d'Arrée. This route along the ridges and through the countryside takes you to the 14-metre-long Mougau Bihan covered walkway, a beautiful peat bog with an interpretive route, and old slate quarries.

Nestled in a green valley, this commune has all the charm of the mountain countryside, with its sunken lanes, hedgerows, streams and rugged terrain. The name of the commune comes from the name of the parish patron saint, Saint Rivoal, formerly Riwall, the name of a large family that emigrated from Brittany to Great Britain in the 5th and 6th centuries. Saint-Rivoal has been awarded the "Communes du Patrimoine Rural de Bretagne" (Communes of Rural Heritage in Brittany) label.

A varied route where you can discover aspects of the Breton countryside that have changed little over time. Cross moors and woods, pass through isolated hamlets to return to the lake and its landscaped surroundings.

The municipality of Châteauneuf-du-Faou wanted to pay tribute to the painter Paul Sérusier, who stayed there and then lived there from 1906 until his death in 1927: creation of a museum, which opened in June 2025, and installation of a trail punctuated by eight information panels passing through places that were sources of inspiration for him.A walk along the banks of the River Aulne and through the woods completes the trail.

Starting from Châteauneuf-du-Faou, the route follows the Nantes-Brest Canal and sunken lanes.

An entrance to Finistère through the Monts d'Arrée gateway: the small medieval town of Plougonven with its parish enclosure is very close to the Gaspern forest. At the southern end of this route, two menhirs stand in a field, seeking company. After extensive restoration, the 15th-century Mézédern manor house is still open to visitors in summer. Religious, secular and natural heritage are all on display here.

Let's take a leisurely stroll along the canalised Aulne for about 6 km, passing three locks. Then let's head back up small roads towards the Notre-Dame de Kerluan Chapel. Let's climb a little further to finally descend back down to the banks of the Aulne.

A hilly route through the countryside with beautiful views of the Montagnes Noires.Passage on the towpath of the stream-to-Brest canal. NB: I have been informed of difficulties between (10) and (11) (see notice from May 2025). In this case, take the shortcut indicated in the practical information section.

Two loops in Gouézec: at an altitude of 279 m, one of the highest points in the Montagnes Noires, the Karreg an Tan summit offers a beautiful 360° panorama of the Aulne valley, the Monts d'Arrée and the Bay of Douarnenez.Its name comes from the fact that, during the Norman invasions in the 9th century, a lookout would light a fire there to warn the population, which could be seen from across the Châteaulin basin. Back at the car park, a second loop leads through the countryside in the lower part of Gouézec.

Route in the countryside and along the banks of the Aulne, the last canalised section of the Nantes-Brest Canal. Discover Saint-Sébastien Chapel.

Make your way gently along the the Aulne following the logging trail. Views over the lock keepers’ houses located on the other side. Passage through the Vieux-Bourg and its St-They church, the birthplace of the parish of Lothey until 1846.
