A beautiful walk in the heart of the Jorasse forest, traditionally very snowy (to reach Avenaz at its highest point). This loop is slightly longer than the Cornillon loop.
From the Cornillon or Lezaive d'en haut parking lots, set off to discover the Jorasse forest, taking the forest road on the way up. The way back is on the Cornillon path, a little steeper but still in the forest.
