GR® 34 marked White and Red
(S/E) At the start of the walk to Berder island (see photo), take the street "Rue du Drénez" in the direction of car traffic.
(1) Turn right into the street "Rue de la Montagne" for 100m, and at the stop sign, turn right into the street "Rue du Perrick", which dead-ends near the shore.
(2) Follow the left-hand path around an oyster-farming site. After passing a small beach, the path climbs back up to two roads "Chemin de Kerdelan", then "Chemin du Moulin".
(3) Turn right into "Chemin de Pen en Toul", from where there's a view of the swamp "Marais de Pen en Toul" on the left. 500 m further on, turn left onto a path leading down to the dike separating the swamp from the cove "Anse de Kerdélan" (see photo).
(4) Cross the dike using the pedestrian walkway on the left of the stone bridge. At the other end of the bridge, turn left onto the footpath. This path runs for about 1.5 km along the brackish-water lagoon, which is rich in biodiversity (see photo).
Unmarked
(5) Continue straight ahead, passing two fountains (see photo). At this point, leave the GR®34, which climbs to the right towards the hamlet of Locqueltas. The path leads to the Saline road, which dead-ends at this point.
(6) Take this road to the left for about 500m, then turn right onto the path that runs behind a shipyard. Approx. 130m further on, first fork in the road (not visible on the map): turn left through an open passage in an embankment. About 150m further on, another fork (not visible on the map): take a second path in the embankment on the right. The path leads to a dead-end in the hamlet of Boulen, which leads to the D316.
(7) Turn left onto the D316 for about 60m to find a wide path on the right (see photo) which leads into the street "Rue Mane ar Velin".
(8) Turn left onto the street "Rue du Danut", which quickly leads to the cove "Anse de Locmiquel". Turn left along the long beach towards Larmor Baden.
GR® 34 marked White and Red.
The path follows the coast past through the point "Pointe du Berchis" to the small beach of the same name.
(9) The path skirts this beach, which may be inaccessible at high tide. Continue along the coast towards Berder island, passing the port "Port Lagaden" (see 2 photos) and the main port of Larmor Baden, where you'll find the landing stage for the island "Île de Gavrinis".
(10) Continue to find the Île Berder passage (S/E).
