(S/E) From the landing stage, walk along the ferry terminal and follow the road uphill. Just around the bend, near the area designated for the civil protection helicopter (H on the map), turn right to follow the coastal path that goes all the way around the island. Pass by the stone Oratory of Notre-Dame du Bon Retour and arrive at the orientation table, which allows you to find your bearings in the archipelago. Opposite, look for the Rocher du Kastel, an imposing mass weighing several tonnes.
(1) Continue along the path that descends towards the coastline to walk along the shore. Pass Anse de Porzh Karn Don, the largest cove on the island, and continue along the west coast path. You will see many rabbits, which are often quite tame. Pass the pebble beach of Porzh Ronan and reach Rocher du Roelen and Anse du Vougeu, a natural viewpoint offering a breathtaking view of Ouessant and the Iroise Sea. On the hill on your left, you will see an old windmill whose roof serves as a landmark. Continue along the coast and its rocky outcrops. Pass the impluvium built in 1976 to collect rainwater on your left.
(2) Turn left to reach the calvary and its enclosure, which offer a beautiful view, then turn right onto a diagonal path to return to the seaside. Continue to the southern tip, Beg Ar Loued, where archaeological excavations have uncovered a dry stone dwelling dating from between 2200 and 1800 BC.
(3) Continue on, noting the small fields sheltered by dry stone walls. Arrive at Anse de Porzh ar Bloc'h, which offers a view of the Îlot de Trielen to the south, which until 1955 was farmed by three seaweed farmers who raised 12 cows and cultivated the land. The ruins can still be seen there. On the left stands an imposing landmark.
Walk along Porzh Bihan Beach, a pretty little beach sheltered from the north winds, and arrive at the slipway and shelters of the old lifeboats, now abandoned for permanent mooring in the harbour. Walk along Penn an Ero Beach, very popular at low tide for its fine sand and turquoise, translucent water.
Reach the shelter of the old lifeboat "Amiral Roussin" (1894-1950), now decorated with magnificent frescoes.
(4) Turn left at the hairpin bend to pass by the Saint-Ronan Well, continue slightly to the right along Rue du Patronage, pass the multi-purpose hall, turn left to join Rue du Canon on the right, which leads to the semaphore, now a museum.
(5) Turn right onto Rue du Sémaphore, pass in front of the five-storey statue of Saint Joseph and arrive at Saint-Ronan Church. Just before this, on the right, is the English cistern. Walk along the right-hand side of the church and, after the war memorial, turn into the small street that runs alongside the cemetery where some of the victims of the Drummond Castle shipwreck are buried. At the crossroads, turn left near the calvary known as the Croix du Karit (1616).
With the rescue centre on your left, turn right onto a small road that leads to the small fishing port and its beach, which you follow on the left.
(6) Go around the port area, pass behind the Drummond Castle Museum and continue along the path along the east coast via the Boulac'h and Feuntinigou beaches with a view of the inlet at the entrance to Molène harbour, which serves, among other things, as a sheltered harbour for passing yachts (view of the Îlot de Lédénez Vraz, accessible on foot at low tide). Finally, reach the pier (S/E).
Set your watches: Molène still lives on solar time (-1 hour in winter and -2 hours in summer).
