We will gather at the foot of the track 4X4 of the river of Galets, privileged gate of our immersion Mafataise. The adventure begins already with these 30min of track, encircled by the impressive green ramparts! At the end of the trail, we will start on a regular trail, several times fording the river. The opportunity for your guide to tell you the exceptional geological formation of this end of the volcano in the middle of the ocean. And then, especially, the story of the settlement of the circus: such as the first "chestnuts", these slaves preferring to flee the plantations to dark unknown mountains, we will drive into the walls to the heart of the circus. Remains of ancient and recent history, we will trace these traces to the first "Ilets", these villages living in autonomy since always, where the past mingles with the present, or time itself seems to have stopped. After a snack in the ilet, we will make the return trip, passing to the nearest river, where we will enjoy a refreshing pool. Back by the track 4x4, abandoning our soul of brown, towards the return to civilization.
