The Sentier was used by the Resistance as a secret path to the headquarters of the Maquis du Picaussel. It leads past the former headquarters - now a memorial to the resistance of the Maquis du Picaussel - the grotto as a former command post of the resistance group and the views of the valley towards Puivert. The path is very steep, slippery and muddy after rain. In the lower area it flows into an agricultural path.
