Access: coming from Quimper on the D783, shortly after the Kroaz Avaloù roundabout, turn right towards Concarneau along the coast. The car park is on the right at the start of Anse Saint-Laurent.
GR®®34white and red signposts (not very numerous)
(S/E) From the car park, at the cove (sign for Plage Sables Blancs 5 km), climb the stairs and follow the road, via a secure wooden walkway, for about 200 m.
(1) Take the coastal path that leads into the wood dominated by conifers (Douglas firs). This path runs close to Anse Saint-Laurent and offers views of the opposite shore, where there is a large campsite. Be careful not to trip over the roots that sometimes cross the path along the coastal trail. Keep to the left of a fence that marks the boundary of a large property and you will reach the first signpost (parking sign).
Turn right and continue along the path, staying as close as possible to the cove, until you reach the end of Anse Saint-Laurent, where you will have a beautiful view of La Forêt-Fouesnant Bay and the beginning of Anse Saint-Jean.
(3) Continue along this second cove, always following the path closest to the ria, until you reach a road. Turn right and follow it for a few metres (signposted Plage Sables Blancs 2.3km).
(4) Turn right and continue along the other side of this cove, which opens out onto the sea (vast panorama). The path turns south-east and goes around the small Kernous Beach.
(5) From here, the path is much wider and easier to walk on. Continue until you reach the large Plage des Sables Blancs, which gradually comes into view. Walk along the beach, pass behind the hotels and continue across several car parks (toilets near the water sports centre).
No signposts
(6) Leave theGR®® trail continuing along the coast and, at No. 13, cross Rue des Sables Blancs at the pedestrian crossing and head towards a car park opposite. Follow the path that runs alongside a sports field on your right. This entire area is currently under development (February 2019) to create a large green space, and the route may be slightly modified.
(7) At the end of the path (signposted Parcours n°1 Vallée de Kerandon), go around the retention basin on the left and follow the path which becomes gravel as it climbs up alongside a campsite. At the top, turn left into Rue du Muguet, then take the first right, Rue des Géraniums, and you will arrive at the Voie Verte (former Roscoff-Concarneau railway line, 143 km, shared with bicycles).
(8) Take this road on the left, go through a barrier and continue for about 1.5 km. Initially enclosed in the urban area, the Voie Verte then opens up to beautiful views of the surrounding countryside. Go over a bridge and continue for about 50 m.
(9) Leave the greenway on the right, go downhill and join a small road. Turn right, go under the bridge and follow this road which leads to Rue des Sables Blancs. Follow this road to the left for about 300m.
(10) Turn left onto Chemin de Lanadan and continue straight ahead until the end.
(11) Turn left onto the path that joins the coastal path and follow it to the right. Retrace your steps until you reach a road.
(4) At the end of Anse de Saint-Jean, continue straight ahead until you reach a car park.
(12) Turn left onto the path that crosses the woods and join the coastal path. At a wooden signpost marked "Point de vue et parking" (viewpoint and car park) (located opposite a campsite on the other side of the river),
(2) Turn right and follow the same route you took on the way there to reach the car park at Anse de Saint-Laurent (S/E).
