Isalo National Park
salo is famous for a landscape reminiscent of the mesas of the American Southwest. Great canyons give way to steep stone mountains full of caves, in which the locals bury their dead. Though the landscape is mostly dry and barren, there are occasional rice fields clinging to the moisture of stream banks. The most famous endemic plants are the "elephant’s foot," a pachypodium that is short and bulbous with a yellow flower, and the pink Madagascar periwinkle.
