Parking near the Verthemex war memorial. The Vierge trail starts just above: directional sign at the side of the road.
(S) Climb left along the path marked in yellow. Pass two paths on the right and follow the switchbacks to reach the Croix de la Rochette in about 40 minutes (viewpoint and sign).
(1) Before the cross, leave the path and turn right, following the yellow markings into a more open area.
This will take you to the mound where the statue of the Virgin Mary stands (altitude 916m, sign and orientation table).
The route rejoins the small road.
(2) Take it to the left to arrive, 200m further on, at the hamlet of La Vellaz: sign, fountain, mural.
(3) At the crossroads, take the road on the right (D42) and follow it for 800m. As you enter the forest, leave the road and take the path that descends to the right.
(4) At the next intersection, La Drettaz, leave the path and descend the trail on the right (steep slope at the beginning). Pass several paths on the left, follow the road you took earlier and then cross it. You will arrive at the first houses of Verthemex and find the starting point, all in about 30 minutes.
