Park in the Chalet d'Arvière car park.
If there are no spaces available, drive back down about 800 metres to a hairpin bend with a car park at point 1.
(S/E) With your back to the Chalet d'Arvière, head right towards the east and follow the red and yellow marked forest path that supports theGRP® Tour du Valroney downhill. Continue on the hairpin forest path, leaving the undergrowth trail on your left, and head towards Grand Colombier.
(1) At this fork, which has been converted into a car park, take the path on the left heading south-east and gradually ascending. The signs on your left indicate Col de Charbemènes and Grand Colombier. Head towards the Sapin Daubrée, an imposing tree.
(2) Keep south onthe GRP®, ignoring all the paths branching off to the right and left. You will reach Col de Charbemènes, a large crossroads of paths.
(3) At the pass, walk a few metres east to admire the best view, then return to take the southbound climb through the woods towards Le Grand Colombier. The climb is steep in these woods before reaching the summit pasture. First, head for the Croix du Colombier. Continue walking south and join the tarmac road from the pass.
(4) Cross it and continue south to reach the summit of Le Grand Colombier, with a wider view of Lac du Bourget.
(5) Return to the tarmac road at the pass crossroads.
(4) Turn left and, after a slight descent, take the path on the right after the hairpin bend to reach the Granges du Colombier. After the barns, you will come to a fork with three paths.
(6) Take the right-hand path, which is almost flat and heads north-east, following the signs for Col de Charbemènes. Continue to the pass.
(3) Look carefully for the northbound path running along the ridge at the edge of the undergrowth. There are no longer any signposts, but there are some yellow markings to guide you.
You are now passing above the Griffe du Diable nature reserve, which is strictly off-limits. Head towards the Platières viewpoint.
(7) Continue north along the ridge until you reach the D123.
(8) Here, take the paths used by cows on the left. Stay on the left-hand paths to reach the downhill path before the hairpin bend on the D123. Here you will find theGR® 9 and 509 and theGRP® du Tour du Valroney.
(9) Take the path on the left and walk past the ruins of the Grange d'en Bas. Continue south, walk past the Grange de Falavier and you will come to the Chalet d'Arvière car park (S/E).
