From Quimperlé town, head south towards the Carnoët state forest (D49). Follow this road and park at the parking lot of the Toulfouën inn.
(S/E) Take the road to the left of the shelter at the far end of the parking lot. After about 1km, you'll come to a car park which is the starting point for a number of forest tracks. Turn left onto the road leading to the village of "Lothéa". Follow a equestrian centre on the left.
(1) After visiting the chapel of Lothéa, the fountain and the bread oven, head back towards the equestrian centre and take the path on your left at the edge of the forest. After approx. 300m, the path becomes sunken and quite steep.
(2) At the bottom of road "Chemin du Duc", turn right uphill for about 50m to avoid the often muddy section alongside the Laïta river. This alternative way returns to the main path after about 600m.
(3) Catch up with the GR®34E and follow the Laïta river. On the other side of the river, enjoy the view of the castle of Bothané located in the commune of "Guidel" (56). After passing the harbour Port de la Véchène and a climb, reach the "Rocher Royal" for a splendid view of the Laïta valley.
(4) Continue along the GR®34E, pass the remains of castle of "Carnoët" to reach the Bichop's Chair ("Chaire de l'Évêque").
(5) Continue until you find a path that curves up to the right in a hairpin bend.
(6) Take this path to catch up with the "Chemin de Saint-Maurice" road and turn right onto it. Admire the magnificent trees, some of which are over a hundred years old. After about 800m on the road "Chemin de Saint-Maurice", you'll arrive at a crossroads.
Turn right, then immediately left. Cross a small stream, then head uphill to reach the forest road leading to the castle of Carnoët.
(8) Follow this road to the left and, at the next crossroads, continue straight ahead to reach the starting point (S/E).
