In a few words
Embark on an adventure to traverse the island of Reunion from the north coast to the south coast ! With a welcome mix of nights in guesthouses and hotels to recharge your batteries, let yourself be tempted by this legendary trek with breathtaking panoramas.
Your journey begins with the ascent of the Plaine des Chicots and the summit of Roche Écrite . Then you venture into the heart of the unspoiled Cirque de Mafate for an extended period of self-sufficiency. Let yourself be captivated by the beauty of the landscape where nature rhymes with rainforest , verdant peaks , and wild waterfalls . Via the Col du Taïbit , you then progress into the Cirque de Cilaos before climbing to the highest point of the island and the southern Indian Ocean, the famous Piton des Neiges . Your trip continues towards the Plaine des Palmistes to reach the La Fournaise volcano and the Dolomieu crater. After feasting your eyes (and your legs!), your circuit ends on the idyllic beaches of Saint Gilles , where the grandeur of the mountains gives way to the soothing beauty of the Indian Ocean.
