Park opposite Tréhiguier harbour, situated on the other side of the Vilaine.
(S/E) With your back to the Vilaine, walk a little over 400 metres up the road heading west towards Coëtsurho.
(1) Before the first right-hand bend, on the right-hand side of the road, a small path – accessed via a chicane – winds its way between two hedges and climbs up the hillside. As you gain height, you’ll be treated to lovely views of the Vilaine estuary. Further on, the path emerges amongst the houses of the hamlet of Kerantréh.
Turn right to join the road leading to the village, then continue straight on at the next junction.
(2) Let the road curve off to the left and take the main track that leads straight ahead. It winds its way past the wind turbines one by one until it reaches the isolated house at Lande Verrien.
In wet weather, the track may be impassable between the second and third wind turbines, as it is poorly drained and may be flooded. In this case, take the neighbouring field on the western side.
(3) Once past Lande Verrien, the track becomes a road. Follow it for about 350 metres, then turn right at the first junction you come to. The path winds its way through a narrow wooded strip before emerging into a more open area at the foot of a hillside. Turn left to walk up the slope. Before reaching the road leading to Trégréhen, the view opens up to the left onto the sea. Below, the massive, square tower of the former Abbaye de Prière stands out against the shoreline.
When you reach the road, turn left and follow it to the first house in the village of Trégréhen. As you pass, note the beautiful granite statue of the Virgin Mary and the curious headdress worn by the infant Jesus.
(4) Turn left onto the path before the first house. When it joins another road, turn left again, follow this road for about 150 metres, then at the first bend, turn right onto the long ridge path leading to Kervéléan. Once again, you’ll be treated to beautiful views of the ocean and the valleys leading to Muzillac.
(5) When you reach the road after the farm, turn left, head back towards the first wind turbine, and turn right towards Billiers at the first three-way junction. Follow this road for about 300 m, turn left and, at the three-way junction immediately after, turn right towards Bourg l’Étang.
(6) Just before you reach the village, turn left, then left again. The path you’re now taking skirts a wetland area, following its edge in a wide bend to the right. As it’s not possible to reach Port Nart directly, head up the hillside to the edge of the Guernehué equestrian centre. When you see it, turn left towards a grove of pine trees overlooking the ocean to rejoin the coastal path.
(7) Take this path, heading to the left. After passing the small cove of Port Nart and its neo-Breton villa, the path follows the coast as closely as possible, leading to Le Moustoir. Depending on the tide, the view over the Vilaine estuary is ever-changing, with the light playing across the water or the exposed foreshore.
Return to Le Moustoir along the water’s edge (S/E).
