(1) At the Charvet car park, take the path on the left (GR®54marked in red and white). It climbs through the undergrowth alongside a stream on our right. The path is well marked and clearly signposted. We cross the stream for the first time, then a little further up, a second time, to find it on our right.
(2) When you come out of the woods, you will reach Bachas, the arrival and departure point for many chairlift cables. The Pas de l'Âne is signposted on the right, but I did not follow this direction. Continue on theGR® which branches off to the left and then very quickly to the right and continues along a rather unpleasant track.
(3) A little further up, we leave theGR® to take a track that branches off to the right. It turns into a path and leads us to the Pas de l'Âne. We then enter the Écrins National Park.
(4) Cross the Pas de l'Âne to descend into the Montagnolle valley. This much wilder section is cool and pleasant. Continue without difficulty towards the Grand Tabuc torrent, leaving the path that branches off to the left into the scree and leads to the Col des Grangettes.
(5) You leave the Écrins National Park and continue your descent on a pleasant path along the Grand Tabuc torrent.
Leave the first path on the left that leads to Les Grangettes, then quickly another path on the right and continue to the first footbridge that crosses the torrent.
(6) Cross this footbridge, pass two paths on the left and reach a second footbridge.
(7) Turn right to cross the stream again. The path turns into a track that will take you back to the starting point.
