Madagascar’s labyrinth of stone

Stone forest

Madagascar’s Tsingy de Bemaraha National Park, situated in the Melaky region on the country’s west coast, is home to some of the world’s most diverse wildlife. On an African island famous for its biodiversity (90% of the species in Madagascar are found nowhere else on Earth), the largely unexplored park is an island unto itself, a kind of bio-fortress that is nearly impenetrable thanks to the massive limestone formation that runs through it.
