A landscape unique in Brittany

The Monts d’Arrée cross Finistère from east to west, at the heart of the Armorique Regional Nature Park. They are not very high, but they feel like mountains: rocky ridges rising out of the moorland, a vast horizon, wind and very few trees. These landscapes are often compared to Ireland or Scotland.

In the past, this poor land supported only a few crops. Today it forms the largest expanse of moorland in Brittany, dominated by gorse and heather and dotted with peat bogs. It is a fragile environment, sensitive to trampling and to fire, as the great blaze of summer 2022 around Mont Saint-Michel de Brasparts showed.

About 45 minutes from Plougasnou, the contrast with the coast is striking. It is an excellent idea for a grey day on the coast, or whenever you feel like a complete change of scenery.

The summits to know

Several summits compete for the title of roof of Brittany, within a few metres of each other. According to the Armorique Regional Nature Park, the two highest points are the Roc’h Ruz and the Tuchenn Gador.

Roc’h Ruz

385 m, the highest point in Brittany, in the commune of Plounéour-Ménez.

Roc’h Trévézel

384 m, the most spectacular ridge, right next to the D785 road.

Tuchenn Gador

384 m, a discreet summit overlooking the Yeun Elez.

Mont Saint-Michel de Brasparts

381 m, with its 17th-century chapel.

The Roc’h Trévézel is the easiest to reach: a short climb from the pass is enough to get to its schist needles and its view over the Léon. The Roc’h Trédudon, 383 metres, is easy to spot from afar thanks to its mast. As for Mont Saint-Michel de Brasparts, its solitary chapel is the emblem of the Monts d’Arrée.

Where to hike in the Monts d’Arrée

Many waymarked paths criss-cross the hills, for all levels. The Armorique Regional Nature Park offers detailed routes, and the GR 380 goes all the way round the massif for long-distance walkers.

For a first visit

Climb the Roc’h Trévézel from the pass, then Mont Saint-Michel de Brasparts: two summits, two atmospheres, less than an hour’s walking in all. Ideal with children.

For a proper hike

The ridge paths link several roc’hs between Plounéour-Ménez and Botmeur, with uninterrupted views over the moorland and the Yeun Elez. Allow half a day to a full day, with good shoes: the rocky sections are slippery in wet weather.

For the legends

At the foot of the summits lies the Yeun Elez, a vast marsh that people once considered a gateway to the Underworld. This is where the home of the Ankou, the figure of death in Breton tradition, is said to be. On a misty day, you can see why.

Villages, ecomuseum and heritage

The Monts d’Arrée are also stone villages and a very lively rural culture. The Monts d’Arrée ecomuseum brings together two sites: the Moulins de Kerouat in Commana, a former millers’ village, and the Maison Cornec in Saint-Rivoal, built in 1702 and preserved in its original state. Check before you set off, as opening periods vary and one of the sites has undergone works.

Further east, the Huelgoat forest and its jumble of boulders round off a day in the Monts d’Arrée perfectly.
