The Isalo National Park in the central-south is the most visited in Madagascar. The park, furrowed of rivers and their affluent, spreads over 81 540 ha. The wild landscape with deep canyons, palm-lined oases and grasslands, is formed by erosion of a plateau of Jurassic sandstone. The park protects a unique treasure of endemic species, including 14 species of nocturnal lemurs.
