• Do not miss the trek, forming a loop near Nébias, the Sentier Nature leading to the natural site of the Labyrinthe Vert. It consists into a meandering path across a very particular karstic maze, lost in a forest of oak and boxwood, among other mediterranean plants. Along the path, you will discover beautiful clearings. Human presence in this landscape is so ancient that the modern walker is following the footsteps of medieval shepherds and even beyond. Within the le Labyrinthe Vert you also can access the "Cami Salvatge" with its "named boulders", stay to meditate on "le Grand Lapiaz" (the Great rock field) or in the "Clot des Encantados" (the Fairies den), not far from the "Sapin Harpe" (harp fir tree).

Walking past the trek opened in 1987, you can reach the château de Puivert, either by a forest track bordering the Sentier Nature next to the Borde d'en Dominique, either by the sentier Cathare at the south coming from the chapelle Sainte-Claire.

• Scenic forest path of the lake du Tury leading to the Montmija observation platform (1000m) then further the one of the Sapin Géant (giant fir tree), in the domain forest of Callong.
