Park along the main street!
(S/E) At the end of the village, take the path that climbs north-north-west and follow it to the point with an altitude of 1278; in its second section, it descends slightly (ignore the paths branching off to the left)
(1) Shortly after the 1278-metre altitude, the path veers to the left; follow it to the junction at the 1486-metre altitude (signpost indicating only Pierre Baudinard and Pierre Orcel).
(2) Take the path branching off to the right, which climbs steeply towards the Clos du Mounard (not signposted).
(3) Once you reach the entrance to the meadow, with the hut in view, climb the embankment on the left and follow the edge of the meadow to a small gate. There is no marked path on this section for about 150 metres. From the gate, the path – which is sometimes a little narrow – winds its way through the broom and fir trees and cuts a line through the grass straight up the slope; follow it to the 1705 mark. Follow a few cairns and finish on the small scree slope.
(4) Now follow the flat path towards the Pivallon valley (north-west). Following a wide bend, reach the shoulder opposite the valley at the 1700-metre mark.
(5) From the ridge, follow the track heading due north, following the contour line (ignore the main path which descends). At the end of this track lies the entrance to the tunnel (200 m), visible only at the last moment, on the left, at the level of the plateau.
(6) Whilst exploring the main tunnel, you will come across several small side tunnels which are not very long. After your visit, retrace your steps in the opposite direction to elevation 1705.
(4) Keep to the right on the path (more of a game track) which continues through the broom and fir trees; follow the clearest track, which tends to climb slightly and leads to the drinking troughs.
(7) Now head across the mountain pasture, following the terrain, to reach the Baudinard rocks, clearly visible in the distance.
(8) At the Pierre Baudinard hut, take the clearly visible path (north of the rocks) and follow it all the way down to the 1278 m point, where it turns to the right; stay on this path, which leads back to the village of Villard Joli (S/E).
