A lovely walk up through the forest to the Ermitage de Notre Dame du Coral followed by lunch at the Auberge and the same walk back down to Lamanère.

Second stage of the Mas Malet loop to the Refuge des Cortalets. Return (descent) to Mas Malet via little-used paths, marked with directional posts (as of July 2025). Allow around 5 hours for the walk. The GPX track may prove very useful in places.Please note: classified as difficult, with a descent of over 1,500 m, but sheltered from the heat and offering beautiful views and refuges. The only drawback is undoubtedly the climb back up to follow the beautiful Chemin des Muletiers from La Mouline (15). There is an alternative route that avoids this by descending via the track. Another more radical alternative is to descend only via the track from (9) to (E).

This is the first stage of the Thués - Fillols loop, which takes you up the Carença Gorge to the refuge of the same name.
