Les Sept-Saints and the Léguer Valley

Forest paths and sunken lanes lead walkers along the "Sentier des Améthystes" (Amethyst Trail) alongside the Léguer and then the Saint-Éturien stream, before arriving at a centuries-old beech tree.
The walk starts and ends at the Chapelle des Sept-Saints: a place of great significance for the friendship between Islam and Christianity.

Description of the walk

Park on the grassy area used as a car park to visit the Chapel of the Seven Saints.

(S/E) Head towards the houses and take the path on the right: signposted "Le sentier des Améthystes".

Yellow signposting

The trail descends towards the Léguer. When you reach the D74, cross the road and continue along the trail opposite.

Red and white markings and yellow markings

This path joins the road, which you follow to the left for a little over a hundred metres.

(1) At the start of the bend, leave the road and take the path that continues along it. When you reach the access road to Traou Léguer, turn left and continue along the path that more or less follows the Léguer.
You will reach the Moulin de Kergueffiou, visible on the other side of the river, on the left.

(2) Take the path that climbs to the right to the houses of Le Rest. In the hamlet, take the road on the left, which becomes a path after 50 metres.
At Prat Morvan, the path becomes a road again. After a left turn, continue along the path on the left. The path descends to reach the Ruisseau de Saint-Éturien. Cross the footbridge.

(3) Turn right and follow the stream upstream.

(4) Continue straight ahead.
N.B. The hike described in the section below arrives at this point via the path on the left and follows the same route until (3).

When you reach a wall, turn left to go around the property and continue up the stream. When you reach the road, turn right to cross the bridge and immediately continue along the path on the left. Continue along the stream, but on the other bank.

No more markings

Turn right onto the path that climbs up a very sharp bend. It continues along the road after the first houses. Turn left onto the first path.

(5) Turn right to walk alongside the farm buildings. When you reach the road, turn right towards Quinquis. Ignore the road on the right and continue straight ahead, then, when you reach a stone building with a tower, take the path on the left.

Yellow markings

You will rejoin the "Sentier des Améthystes - 14km" route. At the end of the path, turn right and continue north until you reach the centuries-old beech tree.

(6) After crossing the road, continue along the road on the left. At the end of the road, turn right.

(7) Ignore a road on the right, continue and then take a wide path on the right. When the path bends to the right, continue straight ahead on the trail.

(8) Tip: turn left. The yellow markings indicate to turn right, but in October 2016 a hornet's nest was reported in the abandoned house a little further on.

No more markings

Follow the path to Kerhuet and take the road on the right. Ignore the road on the right (if you turned right at (8) arrival point on the road). Continue along the road, cross Le Stiffel and arrive at Les Sept-Saints (S/E).

Notes

Worth a visit

The Chapel of the Seven Saints

A magnificent beech tree, with a somewhat tumultuous appearance, several hundred years old, has the distinctive feature of having bark covered with initials, dates and intertwined hearts, sometimes pierced by Cupid's arrows.
A venerable ancestor with beautiful roots that rival its branches, a circumference of 4.70 metres, and a curious life spent listening to the wishes of generations of lovers, this tree is a witness to history.

For photos of these two places, see the hike: From the Old Market to the Seven Saints.

Superb walk with 80% of the route on beautiful paths. The first 8 kilometres are quite difficult with lots of descents and ascents. I recommend it.

A very pleasant, easy route, well signposted (recently) with yellow markings all along the way. Follow the existing signs and not all the directions in the description. Well-maintained paths, few roads except at the end of the route. Highly recommended! The Chapel of the Seven Saints, the Kervinihy beech tree, the banks of the Léguer... there are many beautiful sites to discover on this route.

The tone was set when we discovered the Chapel of the Seven Saints and its dolmen crypt, such beauty and uniqueness.
A beautiful hike that ended with the discovery of the Kervinihy Beech Tree, what a "character"...!!!

The route is very well marked, but we took a wrong turn, perhaps due to a lack of attention or because the signs were not clearly visible. Before arriving at Milin ar Choat, we did not cross the river via a footbridge to reach the other side. Was it at the beautiful little wooden hut that we should have crossed to reach the other side?
In any case, it was a very beautiful hike.
Thank you for your reply.
Kind regards

Nice. A lovely walk, part of which I was familiar with. Didn't take the whole route at the end.
Be careful during hunting season. Make sure you have waterproof shoes during very wet weather, of course.

Along the Léguer, and especially along the Saint-Ethurien, it's magical!
Thanks to the AAPPMA in Lannion, by the way, for maintaining the banks of this last waterway.15

A beautiful hike. I did it in reverse to finish on the trails because there are a lot of roads, but they are not very busy. I extended it by combining it with the route of the old market of the seven saints. Three and a half hours of tranquillity. The best part is along the river with some elevation changes, but the forest is superb. In December, some paths are flooded and muddy, but you can always avoid these sections by going around them through the fields.
