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.
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.

Description of the walk

Park in the fairground square in the village of Commana. Note the truncated granite stele dating from the second Iron Age and Christianised in the Middle Ages.

(S/E) From the fairground square, turn right into Venelle du Bois de La Roche and walk past the school.

(1) At the football pitch, turn left and walk alongside it. At the fork near the sports hall, turn left into a cul-de-sac and at the end, take a pedestrian passage between the houses.

(2) Cross the D11 at the pedestrian crossing and take the passageway that leads to the D211.

PR Marked in yellow by signs at key intersections

Follow it to the right, then turn left towards the Manoir Neuf farm and reach the D764.

(3) Cross it with extreme caution and continue straight ahead along the road. Pass Kerdrein Braz on your right and arrive at a bend in the road.

(4) Leave the road and turn right onto a path, then turn left onto a sunken lane that leads to a road.

Off the marked trail

(5) Turn left towards the hamlet of Mougau Braz. Before entering the hamlet, look for a sign indicating Fontaine Saint-Jean and turn onto a path that leads there (beautiful setting with a wash house). Continue along the path that joins the road to Allée Couverte de Mougau Bihan.

PR Marked in yellow by signs at key intersections

(6) Take a few steps back to join the bog interpretation route (a long route on a superb boardwalk that winds through the bog).

(7) At the exit of the bog, turn right onto a gravel path and follow it until it meets a road. Follow the road to the left, climbing steadily until you reach a bend, where you leave it.

(8) Turn left onto a wide gravel path until you reach some fields, then continue along a narrow path between the broom bushes. This path climbs steadily and leads to the Croaz Mélar crossroads (Croas on the map).

No markings

(9) Turn right onto a wide track that descends alongside a wood and, after about a hundred metres, look for the monumental cross called Croaz Mélar among the fir trees. A passageway provides access to it.

(10) Go back up through the coniferous forest and return to the Croaz Mélar crossroads (sign).

(9) Continue straight ahead on a stony path that leads to the ridge, which you follow in a north-easterly direction on a dirt track that climbs steadily between rocky outcrops. This section offers beautiful views of Commana and the entire Léon plateau to the north, and Montagne Saint-Michel and Lac de Brennilis to the south.

(11) At the crossroads (signposted), continue straight ahead. Looking back, you can see Lac du Drennec to the west, a water reserve for the city of Brest and a leisure centre. Continue until you reach the D11.

(12) Cross this road with caution and continue opposite along a path that climbs past an old slate quarry on your left, which is not very visible. This climb is slightly steeper and you will be walking towards the TDF antenna that provides terrestrial television coverage for most of Finistère and part of Côtes-d'Armor. You will come to a wide stone path on the left.

(13) Turn left onto this wide, downhill track. At a fir tree plantation, leave the stony path and turn right onto a track in the moorland which descends towards the D764, running alongside a wood.

(14) Cross with extreme caution and turn right onto the path that runs alongside the departmental road for about 400 metres before turning left onto a wide, gravel road suitable for vehicles (signposted Restancaroff). Continue to this large hamlet, which belonged to the Abbey of Relecq and has retained its character (houses, bread oven, linen laundry).

(15) Cross the hamlet, deviating slightly from the signposts, and turn left twice to rejoin the signposted local road. Take it to the right and pass through the hamlet of Ponclet Huella, another hamlet with traditional buildings.

Off the marked trail

(16) After about 100 metres, turn right heading north and head towards Ponclet Izella (traditional hamlet). Note the gargoyle and decorations on the roof ridge, a reminder of the former stud farmer who lived in this village. At the exit, turn left onto the road and at the crossroads with a cross, turn left to descend onto the marked trail before a bend in the road (on the left, view of the Roc'h Trévézel ridges).

PR Marked in very discreet yellow

(17) Leave this and turn right onto a narrow dirt track that descends towards a stream, which you cross via a concrete footbridge.

(18) The path uphill has become difficult to follow at the start. Go back up it, following a parallel path through the woods (a short steep climb), and rejoin the path to reach a road near a house. Continue straight ahead and note the premises of the former college, which closed in 2017, on your right. You will arrive at the main road (D11).

(19) Turn right towards the parish enclosure. Enter through the triumphal gate and walk around (you can visit the church, see "Practical information") before returning to the fairground (S/E).

Notes

Toilets at the car park at the start of the trail.
Be careful of the risk of fire. This hike, undertaken in early May 2022, revealed very dry vegetation.

From Easter to the end of September, the church is open from 10 a.m. to 7 p.m.
Outside of the season, the key to the church can be collected from the town hall, Monday to Friday, from 9.30am to 11.30am and from 2pm to 4.30pm, in exchange for a piece of ID.

Inspired byPR®18: "the Blue Stone Trail" in the guidebook "the Armorique Regional Nature Park".

Very poorly marked trail. Luckily, I had the route on my watch and on my phone. The hike was of no interest whatsoever. Once on the ridge, you walk among gorse bushes with virtually no view. Despite the good weather we had, there was a lot of mud and some of the hiking trails were like small streams. So mud and water. Luckily we had walking sticks to help us keep our balance. In short, very disappointed, I wouldn't recommend it.

How about tackling the mountains of Brittany for once, or at least what 300 million years of erosion have left us?
This is a varied and interesting route, with a route along a real dinosaur ridge, especially after a game of hide-and-seek with the Korrigans!
No problems following the route with GPX.

A beautiful hike that I had already done this winter. I like the variety of paths and landscapes. Moderate difficulty. You need good shoes. Excellent signage. Superb peat bogs and ridge paths. Covered walkway and enclosure in Commana worth visiting. Thank you for the well-written description.

Not much to see at the start of the trail in Commana, but the rest of the hike is very pleasant. The last steep climb before returning to the starting point is in a stream bed, so be sure to wear waterproof footwear.

Hello and thank you for your opinion.
I am surprised that the plan is incomplete.
I just downloaded the file: the complete plan is indeed on two pages.
Other reviews have not mentioned this problem.

The short circular starting from the church square via a few uninteresting alleys in Commana was not necessary, and it was possible to access the main road directly without passing through points (S/E) and (1).
And then, the map itself. It was quite a programme, as a small section of the hike was missing from point 1 to point 4 and also on the return from point 14 to point (S/E). Fortunately, we had a hiking booklet that filled in the gaps... Otherwise, no complaints, the rest was perfect and it was a beautiful hike completed in 4 hours and 45 minutes over the advertised 18 km.
I highly recommend this hike, which is best done on a sunny day to fully enjoy the magnificent views.

A very beautiful route, particularly for the covered walkway, the peat bog area (wide, new footbridges) and the view from the ridges. A bit of tarmac at the start and end, but little traffic.

I completed this hike alone at a good pace, taking 4 hours and 10 minutes excluding breaks. The first part takes us out of the village of Commana and into the countryside, then into the woods. A few kilometres into the route, we come to the restored fountain and then the covered alley (a row of covered dolmens). We cross peat bogs on wooden structures for about 1 km, then climb gently towards the ridges, skirting fields and pine forests, which are really pretty! Then there are 6 kilometres of ridges, with a "lunar" landscape bearing the marks of last year's fires. The view is beautiful when the weather is clear at the top. In short, it was very enjoyable, combining sport and nature, very good.

Thank you for this review.
I did this hike at the end of May 2022 and we passed through this hamlet.
We even met someone who lived there and who gave us a very warm welcome.
We spent some time with them talking about the history of this hamlet.
It's a shame if access is no longer possible.

Best regards

Thank you for this beautiful hike under a sun playing hide-and-seek with the clouds, just right for taking photos.

Between points (10) and (12), the moorland was badly affected by this summer's fires. But nature seems to be reclaiming its rights. It is covered with young eagle ferns between the charred bushes.

A slight downside, however: at point (15), it no longer seems possible to take the detour through the hamlet of Restancaroff. A pile of wood across the small road seems to block access. I preferred to continue on the PR.

This is a route that I would highly recommend.
