The hike starts from the biscuit factory car park on Route des Traouïero.
(S/E) Follow Route des Traouïero until you reach the woods on the left.
(1) At the sign indicating the route, take the path on the left and descend to the small pond.
(2) At the pond, turn right and follow the yellow markings.
(3) Veer slightly to the right to stay as close as possible to the Grand Traouïero stream, which you will follow for a few kilometres until you reach the granite pillars lining the path.
(4) Here, take the small grassy path on the left which climbs up to the road at a place called Kerrougant.
(5) Turn left to continue along this road.
(6) Ignore the access road to Kergomar on the right and continue straight ahead. Pass the various turnings on either side and you will reach a sign on the left-hand side of the road indicating the Traouïero valley.
(7) Turn left to go down the path. At the first fork, turn right and follow the yellow "dragon" markings.
(3) Return to the starting point and retrace your steps to get back to the car park (S/E).
