Description of the walk

_ Start_: Go to La Trinité-sur-Mer, and park at the harbour (parking available, paying in season -
other free parking available a little further on).

(S/E) From the car park, walk along the harbour of La Trinité-sur-Mer towards the harbourmaster's office and the south jetty (or môle Éric Tabarly, famous navigator). You are now on the GR®34, marked in white and red. Continue along Cours des Quais and Rue du Men Dû, skirting the basins.

(1) At the end of the harbour, take the coastal path starting at the marine anchor, on the Terre-Plein des Américains. Reach a T-junction.

(2) Continue along the path, which is bordered by several beaches, including the convex Men Allen beach.
Cross "Le Bois d'Amour", with its grand early 20th-century mansions. Continue along the path to the Pointe de Kerbihan.

(3) Continue along the path under the pines to Kervillen. Walk along Plage de Ty Guard, past the blockhouses, to the beautiful sandy beach of Kervillen.

(4) Continue through the salt marshes, once again farmed by a salt worker since 2012. Turn right towards the salt granary, then left at the next junction, and right again as far as Bois des Pins du Poulbert (picnic area).

(5) Cross the wood and turn right after the parking lot to join the departmental road between Carnac and La Trinité-sur-Mer.

(6) Turn right along the D186, following the secure cycle path (be careful, it's a busy road, especially in summer) until you reach Rue de Kervourden, which you turn right onto. Join the Rue du Gréal roundabout.

(7) Turn left. At the next roundabout, turn left into Rue de Kerhino, then right into Chemin de la Hune. Go down to the seafront to find the coastal path.

(2) Turn left again to reach the harbour and the starting point (S/E).

A very beautiful hike that we extended to Carnac beach and back. The section that passes through the old salt marshes and the Kerbihan headland is magnificent.

This walk was part of our two-day Three Capes programme. Locmariaquer, Saint-Philibert and la Trinité sur mer. A simple walk with sublime scenery. Very little frequented at this time of year, which added to its charm.

Lovely walk along the La Trinité sur Mer channel and along the beaches and ocean with a view of the Quiberon peninsula. I recommend it whatever the weather, as the colours are never the same.

A superb customs trail, one of the most beautiful in the Gulf of Morbihan.
As it is very well known, you should not choose it in season in the hope of being alone.

A pleasant walk along a well-developed coastal path, but still very busy in mid-September; return by following the GPS track on your smartphone.

A wonderful, peaceful walk to discover the coast and the beautiful homes between La Trinité-sur-mer and Carnac.
A very pleasant passage beside a salt marsh and under a pine forest.

A very nice route, fairly well signposted except on the inland return. It's difficult without the smartphone app.
The coastal path is magnificent.
Lovely walk.
