Description of the walk

Access: From Quimper, take the old Plomelin road D20 called "Route des châteaux".
Continue to Moulin-Mer, where you can park on the left in a lay-by.

(S/E) With your back to the car park, take the path that climbs to the right, then turn left. The path runs alongside fields and overlooks the road.

(1) When you see the Saint-Roch Chapel (private access), cross the D20 carefully and continue straight ahead. Ignore the two roads on the left and take the path on the right that goes through a pine forest. Continue to the place called Ti Pin.

(2) Turn right and follow the small road that joins the D20. Cross carefully.

(3) Turn left, follow the path along the edge of the road and veer right towards the entrance to Château de Perennou on the right.

(4) At the cross, turn right then take the first path on the right into the woods, which joins a small road near Gorré Bodivit. Follow this road to its end at a car park (picnic tables).

(6) Take the path opposite that descends into the woods. Turn right, reach the banks of the Odet and turn right to follow the river.

(7) Go up to the right and then turn left onto the first path. Follow it first through the woods and then along the edge of the field to reach the Roman baths of Pérennou.

(8) After a self-guided tour (information panels), continue along the path. Cross a footbridge offering a view of the Château du Perennou.

(9) Go back up the road via a small staircase and follow it to the left. At the end of a wide bend, leave the road leading to the Château de Kerouzien on your left and continue climbing.

(10) Turn right onto a path that goes around an equestrian centre. Continue until you reach a road at Kerlec. Continue to the large beech tree avenue.

GR®®38markings

(11) Follow this avenue to the left, which turns right to reach the Lestremeur site (manor house, dovecote, bread oven, fountain and wash house).

(12) Turn left and take the time to linger at this peaceful site. Continue along the path that leads to the edge of Combrit Cove.

(13) The path turns right, passes near a bird observatory and continues along the cove to take us back to our starting point (S/E).

A beautiful hike around the Odet River and south of Plomelin, with plenty of woodland.
I would only recommend this to more experienced hikers in winter or when it rains, as some of the paths are muddy, although there are ways to get around them.

The parking area for starting the walk is a little way back from the road.
Between point 5 and the thermal baths, the signage is a little unclear, and the descent to the Odet is not very accessible by car, so be careful if the ground is wet.
The route indicated on the app to reach the thermal baths is quite different from the actual terrain. In fact, the app alerts you to a significant deviation from the directions.
However, this is not a deal-breaker for those who are used to maps and hiking.
A beautiful hike

We went on a superb hike on Sunday with our two dogs, enjoying sunshine and beautiful views of the Odet River and Perennou Castle.
There were a few difficult sections due to the rain in the previous days, with muddy paths.

Thanks to the person who shared this itinerary!
Varied landscapes, mainly trails in the countryside/woodland/along the banks of the Odet.
There are some interesting sights (thermal baths and the very pretty site of Lestremeur).
The only (short) sections of road are on very quiet roads, despite it being summer.
A superb 10 km ride entirely in the shade, for those who love the countryside.
No problems at all with the GPX route.

I printed out the route description. I only did part of it, from point 2 to point 9. I'm not a very good walker and I'm not very good at finding my way around, so I made some mistakes and had to turn back several times. I used a GPS tracker to follow my route. I thought I would find the thermal baths at point 6 according to the description. They are actually closer to point 7. I finally found them. They are superb. I really like the riverbanks and the woods, which are not too hot and very peaceful. I could have got there more easily by taking the path in the other direction. There are signposts from point 8 or 9, I think. I met five or six people on the way, so it was very quiet. For keen walkers, it's a beautiful route.

Hello,
A pleasant walk. A few hills but nothing too difficult.
As you approach the river, you can see Eric Tabarly's old pontoon.
The Roman baths are a beautiful sight.
There's a lovely view of the Château du Pérennou from the RoSul footbridge.
I'm delighted to have discovered this place.
Thank you.

Best regards.

Through the woods, along the Odet river, a beautiful hike that can be shortened to 8 km if you return directly to the starting point from point 9. After point 6, the trail is now paved along the Odet. Some sections may be muddy, but yesterday it was fine.
Thanks for this hike.

A little tricky to find the start at the top of the car park.
there are two possible paths after the chapel, and we turned too early.
An easy and pleasant walk.

Hello,

i think there has been a reading error:
The point (6) indicates the passage along the edge of the Odet River and then the path that leads to the thermal baths, which are located further away.
The point (8) indicates the fork towards the equestrian centre.
Best regards
