GR®R2 Hiking: Great Crossing of Reunion Island (St Denis to St Philippe)

Starting from Saint-Denis, the GR®R2 trail climbs rapidly towards Roche Écrite, offering a first panoramic view of the cirques, natural refuges once prized by runaway slaves (maroonage). Upon entering the Cirque de Cilaos, hikers discover a unique heritage, marked by the cultivation of vines and lentils, at the foot of the majestic Piton des Neiges, which rises to over 3,000 meters. Nature reigns supreme here: the trail passes from the tamarind forests of the highlands to the lunar landscapes of the Plaine des Sables, a veritable gateway to the Piton de la Fournaise volcano. The route then becomes an immersion in the mineral world, where successive lava flows bear witness to the ceaseless activity of one of the world's most active volcanoes. The final descent towards Le Baril (Saint-Philippe) offers a striking contrast, plunging the vertical, mineral face of the volcano into the deep blue of the Indian Ocean.

Rising from the depths of the Indian Ocean, Reunion Island is a volcanic land of impetuous character, shaped by the majestic Piton des Neiges. Its history is a crossroads of civilizations, marked by maroon communities and the abolition of slavery, leaving behind a vibrant Creole culture and a unique architectural heritage of colorful houses. The island's rugged terrain is revealed through the three natural cirques of Cilaos, Salazie, and Mafate, the latter accessible only on foot. Volcanic activity remains alive thanks to Piton de la Fournaise, one of the world's most active volcanoes, whose lava flows regularly reshape the landscape of the Grand Brûlé. Between the turquoise lagoons of L'Ermitage and the high-altitude savannas, the ecological diversity is exceptional, offering varied microclimates within just a few kilometers.

Distance: 134km, Maximum elevation: 2496m, Minimum elevation: 41m, Total ascent: 10122m
