Warning:
Information on how to reach the starting point, as well as details regarding ?♀️ difficulty levels, ? alternative routes and safety precautions, is summarised in the ‘Practical Information ’ and ‘During the Hike’ sections. Any challenging hike requires preparation, and this very difficult hike is no exception.
Signposting:
Most of the walk is off-trail, and there are no signposts. The yellow markings and the red and whiteGR®® markings are of no use for this walk; following them risks taking the wrong paths.
(Start/Finish) Downstream from the bridge on the D1091, head east along the wide, vehicle-accessible track that follows the Torrent du Rif upstream. Leave the track on your right at the first junction and continue along a narrower path which runs alongside the Torrent du Rif, then winds a few times before rejoining the wide track. This track bends northwards to cross tributaries of the Rif beneath pine trees.
(1) As soon as you reach the Alpe meadows, leave the track and take a path on the left which remains at the same level and joins the torrent’s thalweg further north. Turn left (west) to fords the torrent, then climb up through the meadows, which become steeper and turn into scree dotted with pine trees. Continue the climb, always following the easiest route (avoid dense vegetation!) until you reach the Chemin du Roy, which runs horizontally beneath La Lauzière. Turn right (north-east) towards an alpine chalet.
(2) Head north to go round this chalet and head for the Ruisseau du Plan Chevalier. Follow it north-north-west along the right bank until you come within sight of the ruins of a dwelling. Then cross off to the north-east on the right to join the main path which climbs up the left bank of the valley, at the foot of the large boulders from a rockfall beneath the Arêtes de la Bruyère. The path veers northwards and then enters a series of hairpin bends beneath the Col du Grand Lac (see this photo). At the top of the switchbacks, there is a rocky section fitted with cables. Follow these to the pass.
(3) From the pass, take the path northwards which runs along the left bank of the Grand Lac.
(4) When you reach the northern end of the lake, head north-west to cross its tributary and rejoin a path that quickly reaches a flat area in a small rocky gorge (see this photo – view taken on the descent).
Then move to the right bank of the gorge and head northwards on a diagonal ascent at the foot of rocky ridges and steep gullies. When the ridges turn sharply westwards, turn left, still at their base, and climb up through a wide, grassy cirque interspersed with rocky outcrops (my route takes a wide circular loop to the north, but it is possible to climb due west), until you reach a flat area.
(5) From the plateau, the Col de la Tête de Colombe is clearly visible between two large rocky knolls (see this photo). Climb up at the foot of the couloir leading to the pass, then ascend the couloir, quickly moving to the right-hand side, which is easier.
(6) At the Col de la Tête de Colombe, take an optional detour south-east towards the secondary summit. The route runs along the foot of the ridge and then over magnificent boulders that form a ‘giants’ causeway’ up to the secondary summit (see this photo).
(7) At the secondary summit, head back in the opposite direction towards the pass.
(6) Cross the pass and head up the final couloir (on the right-hand side) to the flat area below the summit. Join the ridges above the Guisanne valley to reach, via the summit plateau, the cairn marking the Tête de Colombe.
(8) After taking in the views and admiring the peaks, begin the descent and return to the pass.
(6) Ignore the secondary summit and descend to the flat area at the foot of the couloir.
(5) From there, instead of heading straight down into the valley, make a wide circular loop to the north, keeping level, to cross a shoulder to the east, below the Col de la Ponsonnière, via a small rocky passage towards the IGN elevation point at 2,508 m.
(9) After the ridge, join a clearly visible path to descend the rocky valley floor, heading south-southeast, to a large grassy plateau. Go round the rocky outcrops on this plateau to the east, following the stream as it meanders peacefully. Follow the stream as it accelerates its descent, turning south, and reach the Grand Lac.
(4). Reach the Col du Grand Lac.
(3) Descend along the left bank of the Torrent du Plan Chevalier. When you come within sight of the Alpe du Lauzet (the mountain chalet you passed on the ascent is therefore on the opposite bank; see this view), continue along the path to the south-east until you reach the footbridge at the Alpe du Lauzet.
(10) Cross the footbridge and, instead of turning immediately right onto the track, continue south-east towards the group of houses at Alpe. Go round these houses to take the correct path heading south-west towards the chapel. Follow this path down until you rejoin the route you took on the ascent.
(1) Follow the path back in the opposite direction to return to the Pont de l’Alpe car park (S/E).
