Notes

(S/E) The car park is located next to the football pitch.

Following a comment from a hiker on 13 October 2019:
Please note
This hike is not accessible in all weather conditions between (4) and (6).
The left bank of the Frémur quickly becomes impassable, submerged under water.
Fortunately, there is a path through the woods, but it takes you a little further away from the meandering landscape of the Frémur.

Worth a visit

(Between) 2 (et) 3: Panorama of Fresnaye Bay.
(Between)3(et)4:: Passage at Port à la Duc. Fromthe 12th tothe 13th centuries, the Knights Templar owned property here and welcomed pilgrims on their way to the Holy Land.
(5) View of Château le Vaurouault.
(10) Note: The return trip on the D43 is not very pleasant, but you can take a detour along what was once a railway line, which is much less busy.

A long finish on tarmac, absolutely endless and uninteresting, except for corn as far as the eye can see. After the old dam, many of the markers have disappeared. Sometimes there are posts with nothing on them, and the few paths near the Saint-Sébastien equestrian centre are completely impassable. It is clear that this circuit is not maintained at all and therefore not used, and vice versa (not used, therefore not maintained). I do not recommend it

A wonderful discovery, along the water, not far from the road, immersed in nature! However, due to the recent storm, trees have fallen on the route around the St-Sébastien reservoir, forcing you to find your own way! The St-Sébastien reservoir has been dry for several years, but planting is restoring the site.

The hike is very pleasant except for the long final stretch of tarmac, which is uninteresting and even dangerous. It would be better to suggest another route, even if it means lengthening the hike.
Starting from point 4, there is a suggested route that also follows the Templars. It is not a circular route, but a racket, but that may be better.

Part of the route is through wetlands, so there are a few tricky sections. Between points 6 and 7, the path is overgrown with brambles and windfall.
It's a shame that the view of Vauraoult Castle isn't clear, as the buildings are remarkable and located in a timeless setting.
We enjoyed this hike, which is different from the usual hikes along the customs officers' path or the banks of the Rance.

A lovely walk, but it's a shame that the last 3 km are on a tarmac road. This section of the district road is dangerous as you have to walk on the hard shoulder (not recommended with young children).

Hello,
We completed this hike in 2½ hours under beautiful late September sunshine.
The dam site and the Templar ruins are a lovely discovery.
It's a shame that there are 5 kilometres of uninteresting tarmac road.

Departure at 4 p.m., arrival at 7:30 p.m. Very pleasant route, wet this year but with detour options. On the D43, we are relieved to have the convenience of leaving this fairly busy road for the old railway line.

A pleasant route, notably offering the opportunity to walk through the old dam, now partially destroyed but featuring new plantations. The grassy sections can be bypassed. There is traffic on the road between points 09 and 10. A detour is made between point 10 and the finish to avoid the main road.

A beautiful, varied route with interesting history. Please note that on 24 August 2020, due to high tides over the previous two days, the path along the left bank of the Frémur was impassable between points 4 and 5. We therefore recommend taking the parallel path through the woods, which is well worth the detour. It should also be noted that, since June 2019, the Saint-Sébastien dam is no longer a dam: it has been partially demolished due to dilapidation. The reservoir shown on the map therefore no longer exists.

Hello,
The problem is that this hike is not suitable in all weather conditions. It had rained heavily before we arrived. The left bank of the Frémur quickly became impassable, submerged under water. Fortunately, there is a path through the woods, but it takes you a little further away from the meandering landscape of the Frémur. Perhaps this should be specified in the description.
All the best, and happy hiking!
