The Glacier de Tré-Les-Eaux is a small glacier located on the eastern flank of Mont Buet running from the lower part of the cliffs to the valley floor below it. Many maps will still show the glacier with a considerable size but these maps are outdated and the glacier is shrinking quite quickly and in summer there is not much left of it. It is likely that the glacier will disappear in the next few years but we are no experts on the matter. 

There is a single trail that runs through the Tre-les-Eaux valley coming from Le Lay and the Vallorcine Valley. It runs the full length of the valley and climbs out at the Col des Corbeaux. We have a detailed trail description for a northern ascend of the Mont Buet summit that passes through Tre-les-Eaux. The trail itself comes close to the glacier terminus but there is no path providing direct access.
