Description of the walk

_ Start _: Park in the church car park.
No official waymarkers.

(S/E) Go around the church to the right and follow Rue du Vieux Four, which continues on the right into Rue de Berder.

(1) At a hotel, turn left into Rue Parc Fetan, then right into Rue du Verger.

(2) At the Y-junction, turn left into Ruelle Etal Berder, which continues on the left into Rue Traversière. Turn right to go down to the ford leading to Île Berder (see practical information for tide conditions).

(3) Cross the ford and immediately turn right onto the wide, counter-clockwise path around the island. The path is shaded by old maritime pines. Depending on the tide level, you may catch a glimpse of the oyster beds. Continue to the southern tip: view of the impressive "La Jument" sea current, Europe's second strongest. To the right, views of Gavrinis and Er Lannic islands.

(4) Continue along the coastal path to discover the East coast. On your right is Île-aux-Moines, the largest in the Gulf of Morbihan. The path winds between venerable trees. At the Northeastern tip, discover Chapelle Sainte-Anne, built in 1865 (now closed).

(5) The path skirts a wide cove. Oyster beds abound here. Return to the ford and cross it again.

(3) Turn left onto the coastal path up Rue de Berder.

Markings GR®34 (White and Red).

Go around the harbour cove, past the pier for the Cairn de Gavrinis, and follow Rue de Pen Lannic. Turn left onto the coastal path around Port Lagaden cove. Continue to join the Chemin de Port Lagaden, which skirts an oyster-farming area on the right and continues to the Pointe de Berchis.

(6) The path skirts a private property on the right, then continues along the Anse de Locmiquel. On the other side, you can see the Pointe de Locmiquel. Continue along a beach, pass behind some houses and join Rue du Paludo.
