Piton des Neiges Summit (Highest Peak)

Piton des Neiges, at 3,069 m, is the highest peak on Réunion and in the whole Indian Ocean island region, and the classic ascent is made as a two-day trip from the Cirque de Cilaos. The route starts from Cilaos village (about 1,200 m), reached by the RD241 from Saint-Louis by car or by Car Jaune bus line 4. Hikers walk up to the Gîte de la Caverne Dufour, the overnight base, then set off around 04:00 to reach the summit for sunrise. The round trip is about 15 km as listed, with around 2,000 m of total ascent, and the route is steady and sustained rather than technical. The lower section climbs through forest and cultivated slopes on stepped paths and stone stairs, while the upper part crosses rocky ground, volcanic rubble and a final rock ridge where the air is thin and cold, around 0 to 5 degrees Celsius at the top. There is little shade above the treeline and the final push in the dark requires a headlamp and sure footing. Key landmarks include the Caverne Dufour refuge, the high plateau below the summit cone, and the summit viewpoint with a view over the cirques of Cilaos, Mafate and Salazie, often above a layer of cloud in the dry season. Overnight stays at the gîte must be reserved in advance, either by telephone on +262 262 31 87 45 or through reunion-rando.fr, and they typically include meals. Water is usually available at the gîte, but hikers should carry enough for the daytime sections. Because afternoon cloud and rain are common, the early summit start also lowers the risk of poor visibility, and hikers who feel unwell or face deteriorating weather can retreat to the refuge or descend toward Cilaos.
