Start from the car park below the cairn, accessible via the small unpaved road marked "Petite Grève" which leads to the port of Barnénez (Quai Louis le Port, for GPS)
(S/E) From the car park, return to the access road to the cairn, then turn left to descend towards Kernéléhen. When you reach the slipway after the diving club premises, take the small alley on the left which leads back to the coast. It quickly leads to the bottom of the Anse de Térénez, which you leave shortly afterwards to return to the Manoir de Kercadoret. At the road, turn left and follow it until you pass the Saint-Gonven Chapel and the few houses that follow it.
(1) Turn left after the last one. A small path cuts across to the Térénez road, which you then follow to the left, using the path running parallel to the road. Return to the road to cross the Corniou, and head back into the woods to follow the footpath.
(2) At Keriou, leave the GR® 34 trail running along the coast and turn right to cross the road. Climb up opposite towards a tall house and, once you have passed it, turn right onto a magnificent sunken path overlooking the Corniou. This path cuts across the hillside until it reaches some ruins, then plunges down towards the stream.
(3) Cross the stream over the stone bridge and bear slightly right to climb up onto a pond dyke. Leave the pond on your right and follow the path that starts to climb up the opposite slope on the left. After a flat section, the path turns right to climb the steep slope of the plateau where the village of Bren is located. On the way up, don't miss the view of Anse de Térénez, which you can see in its entirety.
(4) When you reach the first houses in the village, turn right onto a path that joins the RD76. When you reach the road, cross it and continue to the right for about 100 metres before taking the first farm track on the left.
The place is called Bellevue, and the name is well deserved.
Follow the path that winds between vegetable plots until you come to a small road. Turn right and follow this road to the end. From this point, you will have a view of the entire bay formed by the Morlaix estuary and the many famous sites that dot it: Île Louët, Château du Taureau, Île Noire, and more.
(5) Take the small path that branches off to the left just after the last farmhouse. After a few steep bends, it joins the coastal path.
(6) Turn right onto the coastal path. You can't go wrong, as it is the only path in this area, winding mostly along the foot of the cliffs, a few metres above the shore. There are a few rare access points allowing you to descend to the foreshore, but be careful of the tide. Furthermore, it can be risky to venture to the edge of the sea, as there is no beautiful sandy beach below, but a series of rocky passages of varying difficulty. What's more, the chances of finding the path again are as rare as those of reaching the water's edge.
(7) At the village of Lansaleit, whose houses can be seen on the right of the path, it is possible to access one of the few sandy parts of the coast via a staircase carved into the cliff. If you are not interested in swimming or if the sea is not there, continue straight ahead, following the shore.
Continuing along the coastal path, you will pass just below the cairn without noticing it. However, you cannot miss the view of Pointe de Barnénez, from where Île Noire and Château du Taureau seem so close.
(8) Once you pass the point, you leave the Morlaix River and the path now runs along a clearer horizon, even if Île Stérec still blocks a good part of the view.
(9) Opposite the island, the trail turns right to climb the peninsula, before turning left when it reaches gentler slopes. Continue with the village of Térénez in sight, before coming out onto the road that serves the last houses on the point. Turn left and follow it for a few dozen metres, then cut right to enter a narrow path lined with wooded embankments that leads back to the slipway that provides access to the moorings below. Turn right at the road leading to the slipway to return to the car park where you started (S/E).
