The Great Crossing of Reunion Island by Trail

From the Grand Galet Waterfall , the hike begins towards Piton de la Fournaise for a day full of discoveries. The journey up the Langevin River reveals a succession of varied landscapes: casuarina forests , vegetation typical of the highlands, and terrain marked by volcanic activity.

The route follows part of the famous Diagonale des Fous (Crazy Diagonal ). We first descend towards Nez de Bœuf , an iconic landmark and the first aid station for runners. Along the way, the landscapes transform: the pastures and endemic forests sometimes evoke the hills of the Auvergne region. We then encounter the infamous Mare à Boue trail , notorious for its technical sections. The day concludes with a challenging descent via Kerveguen , which leads us directly into the Cirque de Cilaos , a truly unique natural setting.

The adventure continues with alternating ascents and descents in the lower Mafate mountains. Each step brings you closer to the islet of Grand Place , an isolated and authentic hamlet.
