Passing by Pointe Saint-Efficace in Matignon

Right from the start, you will travel back in time. You will discover a medieval motte-and-bailey castle, then jump back a few centuries further to discover the Guerches, the ancestors of motte-and-bailey castles. Before reaching Pointe Saint-Efficace, you will pass the ruins of a watermill, then those of a tide mill and finally an old tide mill. As you walk along the sea, you will see Fort La Latte. On the way back, the Chapelle Saint-Germain is worth a detour.

Notes

There are toilets under the market halls.
At the Chapelle Saint-Germain, there are three picnic tables in the enclosure.
Good footwear is essential as the route can be very wet. The part of the foreshore towards the Moulin de Roche Noire mill can be slippery depending on the tide.

Worth a visit

La Motte Castrale is worth a short detour. The "Guerches", a moated enclosure dating from the end ofthe 8th century, are interesting to explore.
In the valley, there are several information panels about the monuments, fountains and wildlife. The ruins of the watermill and the old village are worth a stop.
The Moulin de Roche Noire is imposing in its wild setting.
From the coastal path, you will see Fort La Latte on the other side of the bay. You will pass in front of the Pont Robert wash house.

A very pleasant route, combining shaded sections along a river with open stretches across fields offering splendid views of the coast and Fort La Latte, dotted with numerous mulberry and mirabelle plum trees.
We opted to park outside the centre of Matignon, on Rue de Montbran, so we could start our walk straight away in the countryside.
Please note: at high tide, the passage under the Roche Noire is inaccessible. We had to turn back and make a loop on the plateau between the horse fields to rejoin the GR a little further on.

This hike is best done at high tide (even though access to Fresnaye Bay is quite limited).

Of all the walks I've done between Matignon and Saint Suliac, this was my favourite! I wasn't blown away by the very beginning of the hike (undergrowth), but the rest delighted me! When I reached the path along the coast, there was a little mist rising in streaks, the tide was low and the light made the landscape look magical at times. An important detail in my opinion is that you only walk on tarmac at the start and finish! Thanks to GPS tracking, it's difficult to get lost! A word of advice: identify the sections to cover until the next junction and leave your phone in your pocket (or rucksack). Take it out to check it and follow the right route. This way, you'll save your battery and enjoy this beautiful walk to the full!

Walk along the two ponds on the right at the start.
After crossing the road, keep right along the canal before the houses.

Superb route, magnificent scenery. Very easy to follow thanks to your explanations. Not exactly a walk in the park for a 71-year-old granny! The beauty of the landscape makes up for the pain in my calves.

Well-defined route, very pleasant through the woods with magnificent trees, then a country walk along the edge of Fresnaye Bay at high tide under a blue sky. Magnificent. Total duration 3 hours 15 minutes.

Hello,

Thank you for your feedback.

Reliability of the map route: Not used
One caveat: we relied on the literary description of the walk.

The description and the map are inseparable. It is essential to use both tools together.

Furthermore, if you are not confident with navigation, I recommend using the Visorando GPS app in addition to the description and map.

This tool, offered free of charge by Visorando, allows you to validate waypoints and thus remove any doubts you may have about your orientation.

See you soon!

The suggested walk is definitely worth the detour. It offers the opportunity to visit Matignon and various picturesque places in the surrounding area: the motte-and-bailey castle, the valley of sighs, the sea mill and the foreshore. It is varied and easy.

One downside: we relied on the literary description of the walk. Sometimes, based on what was written, we took the wrong route, especially at the beginning. The text should be clarified as it contains some ambiguities. Nevertheless, we managed to find our way!

A beautiful hike,

Nathalie
