To get to the start: from Notre-Dame-de-Bellecombe towards Les Saisies, reach a wide right-hand bend with a platform on the right-hand side. At the entrance to this, turn left towards Les Excoffonières - Plan Désert (lake).
Follow the small road to the end and park near the lake.
(S/E) Continue along the track that passes under the chairlifts and joins the entrance to the farm.
(1) Ignore the access road to the farm and head for the next fork on the ridge via a fairly steep climb.
(2) Continue to the right and enjoy the view of nearby Lac du Gui. After a short climb, the track curves to the right and continues almost horizontally to Mont Rond.
(3) After enjoying the view, return to Lac du Plan Désert via the same route (S/E).
