Start from the central square, Place de la République (large car park).
(S/E) Leave the square at the top and follow Boulevard du Général de Gaulle for about ten metres. Turn left into Rue Laénnec. Walk along the back of the former minor seminary, pass the Tourist Office and you will arrive at Place de l'Église Notre-Dame de Roscudon. Take the time to admire the south porch, built around 1400, one of the most original creations of Gothic art in Brittany (the collegiate church is well worth a visit).
(1) With your back to the porch, take the pedestrian crossing to Rue des Courtils, which you follow to the left to reach Petite Rue Chère.
(2) Go down this cobbled alleyway on the right (the name "Chère" comes from the Old French "choir", meaning "to fall") and you will come to Rue du Goyen.
(3) Turn left and continue along the Pont de Kéridreuff, which replaced the former ford. A tide mill, one of the oldest in Brittany, is built on this bridge. At the end, turn right onto a small road (Rue de Stangalon) and follow it for about 400 metres (view of Pont-Croix).
(4) At the signpost, turn right to get closer to the left bank of the river. Follow the path, which is flat at first, then alternates between a few small ascents and descents in the undergrowth. Cross a footbridge and arrive at a fork preceded by a tree trunk carved into the shape of a mushroom. This fork does not appear on the IGN map.
(5) Turn left before a footbridge and climb into the woods to reach a fountain and a large wash house. This path rejoins the coastal path you left earlier and continues along the edge of fields in a south-westerly direction.
(6) At a sign indicating active oyster beds, leave the carriageway on the left and climb four steps to continue into the woods. Pass a few old boats that are spending their twilight years at the end of the cove. Turn left to climb into the woods where a rope stretched between the trees on the right marks the path and leads to the entrance to the Château de Locquéran.
(7) Turn right and go down the road using the safe passages, first on the left and then on the right. Cross the bridge (view of Audierne harbour on the left). At the end of the bridge, follow the path between the river and the buildings. Go around the "Aqua Show" aquarium and continue along the path below the D765.
(8) At Anse de Suguensou, turn right to cross a small bridge and continue along the old Pont-Croix - Audierne railway line. Pass the Lespoul lagoon on your left, where two signs show the different birds that live there. This 3 km stretch of path is marked by posts every 100 m. A graduated chart allows you to assess your running performance according to your age.
(9) At the car park, you will reach a short paved section. After about 200 metres, turn right (signpost) and continue along the edge of the field. Pass another car park and continue up the river, lined with beautiful restored houses on the left. Pass another car park (information sign on the bridge and the tide mill) and turn left to cross Rue du Goyen.
(3) Turn right and then immediately left to go up Grande Rue Chère, a narrow street identical to Petite Rue Chère but, as its name suggests, wider. There is a nice climb ahead to reach the car park (S/E).
