Le Trélod-Charbon is one of the most emblematic perched synclines in the Massif des Bauges, caused by a fold of a thick limestone layer during the formation of the Alps, approximately 20 million years ago. Raised upwards and flanked by fault lines, is represents a well-preserved example of the sedimentary rock folds in the region. Unusually, its interior contains a series of preserved nummulites (marine sediments from the Eocene period, including an outstanding limestone layer), well-marked by a little rocky ledge.
Access via Bellecombe-en-Bauges and the Reposoir et les Ecuries-devant carpark, then the pass under la Dent des Portes, to reach Trélod. Set off from Doussard (Saury) or Bellecombe-en-Bauges via the Col de Bornette to reach the Charbon via the chalet de la Combe.
