Departure from the Teppe Verte - la Jasse car park, which can be reached via a beautiful forest road accessible from the D207 serving the Col du Grand Cucheron.
(S/E) Head towards the Col du Champet, passing through the Marais du Grand Leyat. This part of the route is mostly covered. At the start, the path goes around a hut. Note the path with a metal barrier on the left; this will be for the return journey. Follow the path northwards, then after a hairpin bend, head south-west.
(1) At the intersection, leave the path and take the trail on the right that joins the Marais du Grand Leyat.
(2) Follow it on the left, keeping to the edge of the forest.
(3) Take the yellow-marked trail on the left that enters the forest.
(4) In the forest, at a signpost, ignore the sign for Chalet du Champet and continue straight ahead, following the sign for the pass on your left.
(5) At the Col du Champet, continue straight ahead. A series of steep slopes leads to a clear ridge path offering numerous panoramic views of the region's peaks, including Mont Blanc.
(6) A final climb takes you to the summit of Grand Chat at 1,992 metres.
Continue south-southeast on the Trois Mollards ridge before descending to Lac des Grenouilles near Col d'Arbarétan (1,772 m). Descend to the Chalet-Refuge d'Arbarétan by initially heading towards Col de la Perche, then quickly turning left and heading towards the chalet.
(8) From the refuge, follow the path on the left towards La Jasse; the route is clear at first, then enters the forest.
(9) At Rocher de la Cra, the route joins the trail coming from Chalet de Barbeloup. Continue straight ahead until you reach the intersection with a path that descends from Col du Champet.
(10) Continue downhill to the right, heading northeast towards La Jasse. Pass the Chalet-Refuge de la Jasse and return to the car park (S/E).
