Go to Le Petit Bornand, then turn right in the village onto the Route de Paradis. Park at the end of the road (the route is signposted in blue as "Lac de Lessy").
(S/E) Follow the wide mountain path south-southwest, which continues along the road. After the Pize chalet, the track enters the forest and comes out near the Lainvouet chalet.
(1) The lake trail starts sharply to the left 150 m before the chalet (signposted Lac de Lessy). The trail then reaches the foot of the cliff and, via a steep climb and a short section with steps, leads to the sharp limestone pavement at the summit. A horizontal traverse takes you to the mountain pasture and then to the Col de la Forclaz.
(2) Just below the pass, leave the wide lake path and take the trail on the right that leads to a small pass (unnamed) at the north-east ridge of the Aiguille Verte.
(3) From the pass, the path first follows the ridge and then crosses the grassy south-east face to reach the south ridge. Follow this to the summit (the crossing of the south-east face can be slippery after wet weather). Caution: the last few metres to the Aiguille Verte are steep and require caution.
(4) To descend, retrace your steps back to the pass.
(3: Quickly leave the ascent route and turn right towards the lake)5:: and the chalets of Lessy.
(6) From the huts, rejoin theGR®96, which completes the tour of Lac de Lessy, and resume the ascent route near the Col de la Forclaz.
(2) Follow the path to the right, retracing your steps until you reach the starting point (S/E).
