Andranomafana is a natural hot spring in the Fianarantsoa region of the southern highlands of Madagascar, where sulphurous water surfaces from the ancient Precambrian basement of the Madagascar craton in a landscape of remarkable lemur-inhabited rainforest. The name Andranomafana literally means 'hot water' in Malagasy, and the springs are integrated into the local communities' traditional use of natural thermal water for bathing within a long thermal tradition. The surrounding Fianarantsoa highland landscape, with its remarkable biodiversity — Madagascar has one of the world's highest rates of endemic species — and the nearby Ranomafana National Park with its extraordinary diversity of lemurs, chameleons, and birds, provides a uniquely exceptional natural setting.
Insider tip — Andranomafana, meaning warm water in Malagasy, is a natural thermal spring on Madagascar's Central Highlands plateau where volcanic basement rock heats groundwater to a comfortable bathing temperature. The site lies amid savanna and eucalyptus woodland characteristic of the Bongolava region. Local communities use the pools for bathing and laundry, giving the place an authentic village atmosphere far from tourist circuits. Access is via unpaved track and is best attempted in the dry season from May to October.
