From Allemond, follow the Route de la Traverse to the Coteyssart car park and on up to the Cabane de Chazeau, which provides a shelter for shepherds in the summer. The path then goes through pastureland and blueberry bushes, climbing up to the Pas du Bessey. It then goes over a rockfall and up to the lake via some steep switchbacks, before continuing steeply up to the Cabane du Chazeau through a forest of spruce trees, with some lovely views over the Pic Blanc, Pic Bayle and Pic de l'Etendard. The hut is halfway up and always open. The path then opens up, crossing through rhododendron bushes. The start of the walk is in woods, continuing along a balcony path after the Cabane du Chazeau and finishes in a rocky environment.
