The hike starts in Comus. In the village, park in the car park in the courtyard of the old village school. The route is marked with yellow PR® signs and follows the GR®367 (white and red signs) on some sections. A few directional signs for "Boucle de Montpié" (blue signs) are dotted along the trail. Part of the route is shared with the "Tour du Boum" hike, another loop maintained by the Caminaïres de Comus.
(S/E) When you leave the car park, turn left and head up towards the top of the village along the Col du Boum road. You will come to a crossroads at the municipal garage.
(1) Take the path on the right and follow the Cathar trail to the Col du Boum, GR® 367 marked in red and white. Cross the road once and go up to the left the second time to reach the pass.
(2) Leave the Cathar trail at the pass and descend to Pla du Boum on the right via a path marked by a sign.
(3) Leave the "Tour du Boum" loop on your left at the signpost and take the path on the right until you reach a crossroads.
(4) Leave the path that climbs to the left and take the path on the right that winds through the heart of Pla du Boum. Follow this path until you reach a forest track, which you then take.
(5) Turn left at the crossroads and continue along the forest track until you reach a second crossroads.
(6) Continue left up the forest track and look for a signpost on the right.
