Starting from the hamlet of Le Crot, about 2 km from Sixt-Fer-à-Cheval via the D907. There is a small car park at the end of the access road.
(S/E) Walk back along the access road to the car park and cross the hamlet of Le Crot. At the bottom, turn right, then left to cross the D907 with care, and take the bridge over the Giffre (Passerelle du Saugy).
(1) On the other side, continue left along a path towards the Cirque du Fer à Cheval (follow this direction until you reach point (5)). Further on, cross a torrent via a footbridge.
(2) At the fork in the road on the other side, head slightly to the left. Walk north-east to a bridge over the Giffre at a place called Le Molliet.
(3) Continue straight on along the path (do not cross the bridge). Follow the Giffre at a slight distance on your left.
(4) At a junction near the Pont de l’Eau Rouge and the D907, turn right. Immediately ignore a turn-off on the right and keep heading east-north-east.
(5) Join the D907 and follow it to the right with caution for about 250 m.
(6) Then turn left, cross the D907 with care and cross the Giffre once more. Next, follow a path that immediately turns right and climbs up the mountainside.
(7) At a junction at a place called Giffrenant, veer slightly to the left towards the Chalet de Prazon and pass a few buildings on your right. Continue straight ahead, north-north-east, and follow the Giffre river, which lies below on your right. Reach the Giffre at a bridge spanning the river.
(8) Carry on straight ahead (do not cross the bridge). Look out for the start of a path on the left just before a turning area and the Chalet de Prazon (refreshment kiosk).
(9) Turn left onto this path towards the Refuge de la Vogealle via the Pas du Boret. Climb gently over a few sections of flat rock whilst crossing a few streams. Then continue along a long, exposed section; the whole route is very well equipped with numerous cables but requires care: for further details, see the Practical Information section. Then head up through the forest to reach the Chalet du Boret (refreshment hut) in open terrain.
(10) Continue to the left, west-north-west, towards the Refuge de la Vogealle, signposted as a 1½-hour walk. Go round the Pierre du Dard (elevation 1,635) on the left. Continue the ascent, keeping a northerly bearing, until you reach a junction near the Refuge de la Vogealle.
(11) Continue towards Lac de la Vogealle (do not cross the stream). Carry on to the first junction, about ten minutes’ walk away.
(12) Then turn left, leaving the path leading to the lake. Follow a steeply sloping path running alongside a stream until you come to a rocky outcrop.
(13) Proceed very carefully through the Pas à l’Ours. Amidst black schist, continue along a narrow, very exposed ledge, where even the slightest misstep is absolutely forbidden (see the ‘Practical Information’ section for further details). You will then reach a flat area.
(14) Head right (west) and leave a hillock (elevation 2193) on your left. Then head west-south-west, first across a grassy slope and then through scree. Next, follow a sort of narrow pass. At the foot of the Pointe Rousse des Chambres, head south to reach the Col des Chambres on the edge of the Grand Névé. In the past, snow used to lie in this area all year round, but this is no longer the case.
(15) Continue south-south-east off the beaten track and without markings, following the cairns. Watch out for possible snow and sharp limestone pavement (see the ‘Practical Information’ section for further details). You will then reach the summit of thePointe de Bellegarde and its magnificent panorama.
(16) Turn right (south-west), crossing a few sharp limestone pavements, until you reach the Col de la Boîte aux Lettres. Then head left to quickly reach the Boîte aux Lettres itself.
(17) Turn to follow a long crevice in the rock (hence the name of this section). Descend steadily down a rugged slope with a few sections equipped with cables or chains. You’ll reach a small flat area.
(18) Continue the descent along the edge of the scree slope, following a few cairns and Yellow Arrow markings: please note, this section is almost entirely off-track.
(19) The route reaches the Arête de Trécot near a secondary summit: this is a lovely viewpoint, but watch out for the overhanging cliff not far away. In an area that is still largely off-trail, head right along a descending track and reach a flat section which you should follow for its entire length. Then follow a path to the left and, further down, reach another flat section.
(20) Continue the descent south-west along a fairly even path. Then head south and descend steeply. Watch out for any herds in the vicinity (on my last visit, the enclosures were located off the route).
(21) Further on, head west-south-west and descend via a series of tight hairpin bends. Continue down a fairly gentle slope to the Chalets de Salvadon.
(22) Carry on straight along the path to reach the bottom of the valley. Then turn left. Join a track suitable for vehicles and follow it as it continues.
(23) At a junction at a place called Croix à Augustin, veer slightly to the right (south) and enter the forest. Descend steadily along a series of bends.
(24) When you reach a stream (with a waterfall on the right), continue descending for a long way along winding paths through the forest.
(25) At a junction, carry on straight ahead and downhill, ignoring the path that climbs up to the right. Then pass a few turn-offs on the left and head for the Crot car park (S/E).
