Mine canal and Rivière d'Argent in Huelgoat
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.

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.
The Monts d'Arrée
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.

Mougau Vihan covered walkway and the Monts d'Arrée ridges from Commana
Between the 16th and 18th centuries, thanks to linen weaving, Commana enjoyed a period of prosperity, which explains the richness of its parish enclosure.

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.

Saint-Rivoal has been awarded the "Communes du Patrimoine Rural de Bretagne" (Communes of Rural Heritage in Brittany) label.

Paul Sérusier and Aulne River Circuit in Châteauneuf-du-Faou
