Description of the route by the creator

From the "Paradis" parking lot, follow the signs to the Col de la Forclaz. Once at the pass, there are several possible routes: either to the lake, or to the right, up to the Col de Buclon. From here, you can climb to the summit of the Aiguille Verte. The climb is not particularly difficult, just a little steep. Return along the same path, then turn right at the col to reach Lac de Lessy. You can then go on to the Col de Sosay for a lovely view of the Solaison plateau. To return, take the same path, passing the lake and returning to the parking lot.
