June 2026: following rockfalls, the path is closed from ::8::. This moderately difficult circular route will take you through a particularly wild stretch of the Rhône.

Charcoal burners produced charcoal in the mountains by piling wood into heaps which were then set alight. Part of the wood was consumed as it burned, consuming oxygen, whilst the heat from the wood transformed the rest into charcoal. This process was carried out directly in the forest, as close as possible to the source of the wood. The forests of La Michaille, like many other French forests, supplied this charcoal, which was used until the mid-20th century for heating and cooking.

A lovely circular route, skirting the headwaters of the Parnant (a small tributary of the Rhône) and offering varied routes through farmland, woodland or across an ancient glacial moraine where the views are stunning. Moderator’s note -problem in (2), see reviews 02/08/2022
