Departure: the Col de la Charmette car park, driving up via Saint Egrève, Proveysieux and Le Gua.
(S/E) Head north up the forest path towards the Chalet de la Charmette.
(1) At the chalet car park, go to the left and take the wide forest path towards Col d'Hurtières. The forest path runs south for 100 metres.
(2) At the fork, leave the path on the left and climb westwards for about 200 metres. After this first short climb, the path continues south-west. Follow the yellow markings during the climb.
(3) Continue along the forest path opposite.
(4) At the edge of the forest, pass a narrow section with the Rocher de Pré Large on your right. The Plaine de Varavey opens up opposite. The markings become virtually non-existent. The herds leave tracks on the ground that are roughly parallel and can be followed. Generally speaking, leave the forest on your left and climb up the plain following the tracks heading west. You will reach a fork.
(5) At the signpost: Prairie de Varavey - altitude 1,655 m, turn right towards the north in the direction of Col d'Hurtières (1.3 km and 25 minutes). You will come to another path running perpendicular to this one.
(6) At the top, take the path on the right heading north-northeast and continue along the ridge towards Col d'Hurtières.
(7) At the pass, continue north on the highest path to pass as close as possible to the rocks on your right. The slope is steep but not dangerous. Caution: do not take the marked path, as it descends and you will then have to climb a significant elevation gain without being able to reach Goulet d'Hurtières directly, except via Col de la Sure, which makes the route longer. You will arrive at a fork at Goulet d'Hurtières.
(8) Goulet, not signposted but very easy to spot once you reach the entrance! Turn right towards the east and climb the gully for about 10 minutes. The slope is steep but the difficulty is offset by the view. Pass the gully and descend the well-marked path heading east, which is not signposted, and which takes you back to the first forest path.
(9) Turn right towards the south and continue downhill.
(10) Turn left, and the path descends eastwards (to be honest, we did not see the right-hand fork indicated on the IGN map; the path seems to head eastwards on its own). This will take you back to the forest path you started on.
(3) Turn left towards the northeast and head towards the Chalet de la Charmette and the Col de la Charmette (S/E).
, so I moved on quickly...
