I did this hike in November, when there are few visitors. A very beautiful hike with lots of interesting things to see.
You can sample oysters and the trail is perfectly marked.
I made a video about this hike that shows what you can discover there: https://youtu.be/cbXv37r31JI. Thank you for this discovery."

Shortly after the start, we left the initial route at the sports complex, heading for OZON on the left. We joined a road and then turned right after 50 m to discover BILHERBON l'Ance de MANCEL, an explanatory sign located at the start of the dyke, where we took the GR 34 on the right. Then a drizzle accompanied us for part of the way to Port Anna.
A small variation towards the end to go in the direction of CANTIZAC .towards the church you can discover on the front of a house a portrait of a Breton woman from the village made with hundreds of photos of the inhabitants ... Surprising!

In order to lengthen the kilometres, we turned left at the stadium in the direction of OZON. We reached BILHERBON at the foot of the Mancel inlet, leaving the old dyke that became a road in 1888, turn right to follow the GR 34 and get back on the original route.
A stop for oyster tasting and a drink along the way, a good time even if a drizzle accompanied us to remind us that we were in Brittany.

hello,
it seems to me that giving a 4/5* and a score of 4 is a positive response.
Taking up the presentation of the Séné commune site, it seems to me, is to encourage walkers to venture there.
In other words, it means that I've enjoyed it... and I'd add that you can stop off to eat some oysters with a glass of white wine at the oyster-farmers'.
Sincerely

Hello Zelda33,
Thanks for your comment, but it doesn't say what you think of the proposed hike?
For those of you who don't want to do a round trip, we simply wanted to offer this short circuit, most of which follows the GR34.
Enjoy the walk

This circuit crosses and intersects several "sinagots" paths laid out by the commune of Séné. Here's what the commune's website has to say about it:
More than 70 kilometres of paths criss-cross the commune of Séné.
The coastal paths and country lanes have been laid out so that walkers, hikers and mountain bikers can discover different views of the commune as they go: Port-Anna, the Pointe du Bill, La Garenne, the many bays, the marshes and mudflats, the nearby islands of Boëde and Boëdic, not forgetting the fishing villages with their typical houses: Montsarrac, Cadouarn, Moustérian...''.

These routes, which are accessible to all, allow you to appreciate the authenticity and picturesque character of Séné''.

Very nice walk. With magnificent views. The paths were well signposted. A few muddy and difficult sections (during the rainy season), but the scenery was well worth the effort.
