From the Bonavau refuge (1550m.), return approximately 400m in the direction you came to reach the circuit trail via a footbridge over the powerful Saufla torrent. The trail climbs up gradually, going through the Rossetan mountain pasture (1650m.) and passing by Metecoui chalet (1775m.). There is a great viewpoint from here over the valley and the magnificent areas of Planachaux, Les Crosets and the Portes du Soleil.
A further effort is required to reach the two small lakes at Antheme (2035m.), but it will be worth it to discover this leafy haven of peace and calm, set on a plain bound by the crest of Sélaire and the Dent de la Chaux. The Antemoz hut (2037m.) sits just below.
