Park in a lay-by on the road marked as a car park on the map, below the Chalets du Cours d’en Haut.
(S/E) Follow this road until you reach the signpost indicating the Lac Bleu path at a three-way junction.
(1) Turn left and carry on to Lac Bleu. The path climbs more or less alongside a ski lift and continues further up.
(2) If you wish, without adding much to the walk, you can visit Lac Blanc, but our route takes us via Lac Bleu, which has an impressive blue colour despite the water’s clarity. A very beautiful spot. Follow the path alongside this lake and rejoin the grey path you left at the top of the chairlift, on the other side.
(3) The IGN map shows a path leading off opposite towards Les Balcons. This is what’s shown on the attached map. For my part, I climbed higher up this grey path until I reached a flat area. You then need to cross the track towards the start of the path, which is clearly visible opposite, on the slope.
(4) It’s a lovely path along the mountainside. However, there’s a very short section where it becomes narrower and slopes steeply. This is no doubt due to the crumbly nature of the ground. Depending on its condition on the day you’re walking, it might be wiser to turn back.
On that particular day, it was safe to cross. Afterwards, you make your way between sinkholes—still covered in snow in July—and rocky outcrops, before reaching a flatter section with a small lake (a large pool).
(5) The path then follows the edge of the ledge. There’s a bit of a ‘run’ before reaching a lovely stretch near the Roche Cornue.
(6) This is followed by the start of the descent along the fairly narrow ridge to the top of the ski lift.
(7) The descent continues to the right along a well-marked path that is very uneven due to livestock grazing.
(8) Join the gravel road and follow it back.
(1) Carry on straight ahead towards the (S/E) .
See the ‘Practical information’ section regarding the path after the (3).
