A volcanic caldera reachable only on foot where hamlets cling to ridges above cloud.
No road reaches Mafate. Every person, every bag of rice, every sheet of corrugated iron arrives on foot or by helicopter — the caldera is sealed by 1,000-metre walls on all sides and the hamlets inside cling to ridges above a cloud layer that fills the basin most mornings. The Cirque de Mafate in France sits in Réunion, a volcanic island in the Indian Ocean, and the isolation is not a metaphor. It is the landscape.
The Cirque de Mafate is one of three caldera-like formations in the interior of Réunion, a French overseas department east of Madagascar. The cirque was formed by the collapse and erosion of the Piton des Neiges volcano — at 3,070 metres, the highest point in the Indian Ocean. Mafate's approximately 750 inhabitants are spread across a dozen hamlets connected by hiking trails — the GR R1 and GR R2 traverse the cirque as part of Réunion's long-distance path network. Ilet à Bourse, La Nouvelle, and Aurère are among the principal settlements, each served by a handful of gîtes offering Creole meals and basic accommodation. The cirque walls reach heights exceeding 1,000 metres, and the interior receives heavy rainfall that feeds waterfalls cascading from every rim. UNESCO inscribed the Pitons, Cirques, and Remparts of Réunion as a World Heritage Site in 2010.
Solo
The multi-day trek through the cirque — gîte to gîte, ridge to ridge — is a walk into genuine isolation. The absence of roads isn't a limitation; it's the experience. Each hamlet earned by the trail feels like a discovery.
Friends
The shared effort of the trails bonds. The gîtes serve cari and rum arrangé after the day's walk, the cloud fills the caldera below your ridge, and the remoteness turns every evening meal into a celebration of arrival.
Cari poulet — Réunionnais chicken curry simmered with turmeric, ginger, and fresh thyme over rice.
Rhum arrangé — rum macerated with vanilla, lychee, or local fruits, sipped after the trail.
