Mougau Vihan covered walkway and the Monts d'Arrée ridges from Commana

Between the 16th and 18th centuries, thanks to the linen weaving industry, Commana enjoyed a period of prosperity, which explains the opulence of its parish churchyard.
From the village, dominated by the 57-metre-high bell tower, the view stretches northwards over the Léon plateau and southwards to the ridges of the Monts d’Arrée.
This route along the ridges and through the countryside takes you past the 14-metre-long Mougau Bihan Covered Walkway, a beautiful peat bog with an interpretive route, and former slate quarries.

Description of the walk

Park in the Place du Champ de Foire in the village of Commana. Look out for a truncated conical granite stele dating from the Second Iron Age and Christianised in the Middle Ages.

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

(1) When you reach the football pitch, turn left and walk alongside it. At the fork in the road near the sports hall, turn left into a cul-de-sac and, at the end, take a footpath between the houses.

(2) Cross the D11 at the pedestrian crossing and take the path leading to the D211

PR® Marked in yellow with signs at key junctions

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 reach a bend in the road.

(4) Leave the road and turn right onto a track, then turn left onto a sunken track which leads out onto a road.

Unmarked section

(5) Turn left towards the hamlet of Mougau Braz. Before entering the hamlet, look out for a sign pointing to the Fontaine Saint-Jean and turn onto the path leading there (a lovely spot with a wash house). Continue along the path, which joins the road, until you reach the Allée Couverte de Mougau Bihan.

PR® Marked in yellow with signposts at key junctions

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

(7) On leaving the peat bog, turn right onto a stony track and follow it until it joins a road. Follow the road to the left, climbing steadily, until the bend where you leave it.

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

Unmarked

(9) Turn right onto a wide, carriageable track that descends alongside a wood and, 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.

(10) Head back up through the coniferous woodland to reach the Croaz Mélar crossroads (signposted).

(9) Continue straight on along a stony track which leads to the ridge line; follow this north-eastwards along a dirt track that climbs very gradually amongst the rocky outcrops. This section offers fine views of Commana and the entire Léon plateau to the north, and Montagne Saint-Michel and Lake Brennilis to the south.

(11) At the crossroads of footpaths (signposted), continue straight ahead. Looking back, you can see, to the west, Lake Drennec, a water reservoir for the city of Brest and a developed leisure centre. Continue on to the D11.

(12) Cross this road with care and continue straight ahead along a path that climbs, passing close to an old slate quarry on your left (though it’s not very visible). This climb is slightly steeper, and as you walk, keep your eyes on the TDF mast that provides terrestrial television coverage for most of Finistère and part of the Côtes-d’Armor. You’ll reach a wide stony path on the left.

(13) Turn left onto this wide, downhill track suitable for vehicles. At a fir forest, leave the stony path and turn right onto a narrow track across the moorland that descends towards the D764, running alongside a woodland.

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

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

Off the marked trail

(16) About a hundred metres further on, turn right heading due north and head for Ponclet Izella (a traditional hamlet). Note the gargoyle and the decorations on the roof ridge, a reminder of the former stud farmer who lived in this village. On leaving the hamlet, turn left onto the road and, at the crossroads with a cross, turn left to rejoin the signposted route before a bend in the road (on the left, a viewpoint over the ridges of Roc’h Trévézel).

PR® Marked in very faint yellow

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

(18) The path leading uphill is somewhat difficult to follow at the start. Follow it by taking a parallel route through the woods (a short, steep section) and rejoin the main path to reach a road near a house. Continue straight on and note, on your right, the premises of the former secondary school, which closed in 2017. You’ll arrive at the main road (D11).

(19) Turn right towards the parish churchyard. Enter through the triumphal arch and walk around it (you can visit the church – see “Practical Information”) before returning to the fairground square (S/E).

Notes

Toilets are available at the car park at the start of the route.
Take care due to the risk of fire. This walk, undertaken in early May 2022, revealed very dry vegetation.

From Easter to the end of September, the church is open from 10.00 to 19.00.
Outside the tourist season, the key to the church can be collected from the town hall, Monday to Friday, from 9.30 am to 11.30 am and from 2 pm to 4.30 pm, upon presentation of a valid ID.

Inspired byPR®®18: ‘the Pierre Bleue 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.
