Mougau peat bog and the Commana ridges

Park in the car park near the Mougau Bihan covered walkway.

(S/E) From the car park, take the path leading to the covered walkway and take the time to explore it, trying to spot the engravings on the pillars (not easy to make out). With your back to the covered walkway, cross the road and enter the bog to follow the interpretive route (a long route along a superb boardwalk that winds through the bog). Continue until you reach a junction on a stony path.

(1) Leave the bog route, turn left at a right angle and head up towards the ridge line along a path through heather, broom and ferns. This climb is quite steep but steady on a stony path (schist). You’ll emerge onto the ridge, where you’ll find the PR® “Les Pierres Bleues” (viewpoint over Lake Brennilis and the Tuchenn Kador peak at 385 m, which obscures the summit and Saint-Michel Chapel).

(2) Turn right and follow the ridge, which offers afine view of Commana and the surrounding countryside. Pass close to old slate quarries hidden amongst the vegetation. Continue to the Croas Mélar crossroads (signposted).

(3) Carry on straight ahead along a wide, carriageable track that winds down through a woodland; after about a hundred metres, look out for the monumental cross known as Croaz Mélar amongst the fir trees – there is a path leading to it.

 (4) Retrace your steps back to the Croaz Mélar crossroads (Croas on the map).

(3) Turn left, begin a steady descent along a narrow path lined with broom and arrive at an area of fields and meadows.

(5) At the PR® fork in the road, take the right-hand branch and continue until you reach a road.

(6) Ignore the road leading to the hamlet of Roscoat and its imposing farm, and carry on straight ahead along the road for about 400 m.

(7) Take a sharp right-hand bend onto a stony track to re-enter the peat bog and return to the fork in the path from the outward journey.

(1) Turn left and, following the route in the opposite direction to the outward journey, return to the car park at the covered walkway at Mougau Bihan (S/E). 

Between (1) and (2), the climb is quite steep but steady.

There are numerous information boards in the peat bog.
