CHYULU HILLS

The Chyulu Hills is a mountain range in Makueni County in southeastern Kenya. It forms a 100-kilometre-long volcanic field in an elongated northeast–southwest direction. Its highest peak is 2,188 metres high.

The Leviathan Cave (also known as Kisula caves) in Chyulu Hills National Park is about 11 km long, one of the longest caves in Africa. The national park is part of the Tsavo conservation area which covers Tsavo West National Park, Tsavo East National Park and the Kibwezi Forest.

The park's main gate is in Kibwezi in Makueni County.The Chyulu Hills are located about 150 km east of the Kenya Rift. The hills consists of several hundred small flows and cones. Volcanism in the area started about 1.4 million years ago in the northern parts of the hills, and over time the volcanism propagated towards the southeast. These volcanoes are still considered active, since their last two eruptions (Shaitani and Chainu) occurred in 1856. Within the hills is the Leviathan Cave, one of the longest lava tubes in the world.

Kibwezi town is located 30 km northeast of the Chyulu Hills.

The Chyulu Hills do not have any permanent rivers, but rainfall on hills feeds the Tsavo and Galana rivers and Mzima Springs on the surrounding plains.

Chyulu hills divide the Tsavo and Amboseli plains. The area is inhabited by Maasai and Kamba people.
