Starting point: Chapelle des Trois Fontaines on the D785 leading to Pleyben.
(Out and back) Take the small road, leaving the chapel and its damaged wayside cross on your left.
(1) At the three-way junction (cross), follow the road that climbs to the right towards Kernevez, Kerlann and Ty Ridou. Continue along this road, passing Kerzerrien and Pennaguer. On your left, you will see the summit of Karreg an Tan.
(2) After Kerarmet, when you reach the road coming from Edern, turn left. At a cross, turn left to reach the car park, the starting point of the climb.
(3) Begin the ascent along the well-marked path. The climb is relatively short. There are steps just before the summit. At the top, there is a sweeping panorama over the Châteaulin basin and the Monts d’Arrée to the north.
(4) The descent follows a narrow path marked in places by yellow and orange cairns. The route is not always obvious as there are numerous alternative paths used by mountain bikers. Stick to the path that heads to the left and goes round a coniferous woodland.
(5) Turn left at a 90° angle, pass between two coniferous woods and turn right to head straight down a small road.
(6) Turn left and follow this road, which leads back to the starting point via Ménez Crenn and Baradozic. You’ll pass the junction again that you came across on the way out.
(1) Head to the nearby chapel (S/E).
