Mt. Suswa in Kenya – 50 kilometres away from Nairobi – is a volcano like no other: it hosts a multitude of life both above and below its surface. Underground tunnels were formed thousands of years ago by rivers of lava. One of these caverns is the “Baboon Parliament” as the local Masai named it. Remarkably, Suswa is the only known place in the world where olive baboons roost in caves. Mt. Suswa’s rugged flanks conceal an untouched treasure trove of biodiversity hidden inside its craters and in the deep and mysterious scars left behind by its turbulent past. Featured mammal species are the olive baboon, rock hyrax, bat-eared fox, African wild dog, spotted hyena, Kirk’s dik-dik, klipspringer, large-eared free-tailed bat and the African elephant.
