Chyulu Hills National Park

Chyulu Hills National Park protects part of a young volcanic range running for about 100 kilometres between Amboseli and Tsavo West, gazetted in 1983 and reached from the Mombasa road at Kibwezi. Kenya Wildlife Service calls it the Green Hills of Africa. It is a water catchment before it is a game park, and understanding that is the difference between a rewarding visit and a disappointed one.

The Hills Are a Water Tower, and That Is the Story

The Chyulu range has no permanent rivers. It is built of porous lava and volcanic ash, so rain and coastal mist do not run off the hills, they sink into them. The water travels underground and resurfaces roughly 50 kilometres away at Mzima Springs in Tsavo West, where an estimated 90 million litres a day emerge from the ground.

That is why the Tsavo springs run clear and cold in the middle of dry bush, and it is why the Chyulus matter far beyond their visitor numbers. The system supplies water used well downstream, including on the coast. Protecting rainfall on a range almost nobody visits is what keeps a famous spring in a famous park flowing.

The Chyulu Hills REDD carbon project, covering approximately one million acres including the national park, Kibwezi Forest Reserve and the Mbirikani, Rombo and Kuku group ranches, exists largely on that logic: the value of the hills is in what they hold and release, not in what can be shot, grazed or driven across.

Some of the Youngest Volcanoes on Earth

Volcanism in the Chyulus began roughly 1.4 million years ago at the northern end of the field and migrated south-east over time. The two most recent eruptions, Shetani and Chaimu, occurred in 1856, which is recent enough that the lava still looks raw. Both names are spelled several ways in the literature. Both of those flows sit at the Tsavo West end and are described on the Tsavo West and Shetani Lava Flow pages.

The high ground reaches 2,188 metres, and above roughly 1,800 metres the hills carry montane forest, which is where the birding is best. Below that the country is grassland and thicket. The combination of green ridges, volcanic cones and long views towards Kilimanjaro is unlike anywhere else in southern Kenya, and it is the reason the range keeps getting described in terms borrowed from literature rather than from ecology.

Leviathan Cave and the Lava Tubes

Beneath the hills runs Leviathan, also called Kisula, a lava tube about 11.5 kilometres long. Kenya Wildlife Service describes it as the world’s second longest lava tube; it is in any case the longest and deepest known in Africa.

This is a serious cave and not a walk-in attraction. It requires proper equipment, experience and arrangement in advance. What the system is, how it was surveyed and what caving in Kenya involves are covered on the caving in Kenya page rather than here.

Wildlife, Including the Rhino Almost Nobody Knows About

Elephant, buffalo, lion, leopard and a long bird list occur across the range, and the forested western sector is the birding ground. Game viewing is harder work than in the neighbouring parks: the vegetation is thicker, the animals are less habituated and the densities are lower than in Amboseli or Tsavo.

The park holds something the bigger parks lost. Eastern black rhino were believed extinct across the Greater Amboseli ecosystem until rangers located a remnant population in a remote part of the Chyulu Hills, and a 2008 study put the minimum at 14 animals. They are not a sighting to plan a trip around and are not shown to visitors, but their survival is a large part of why the park is protected as tightly as it is.

Walking, Riding and Hiking in the Chyulu Hills

The Chyulus are one of the few Kenyan national parks where the point is to get out of the vehicle. Kenya Wildlife Service lists hiking, picnicking, game viewing and birdwatching as the activities, and the ridge walking with Kilimanjaro on the southern horizon is the draw.

Riding is the unusual one. Chyulu Hills is one of only four Kenya Wildlife Service parks where private horses are permitted, alongside Hell’s Gate, Mount Longonot and Ol Donyo Sabuk, and the service publishes a charge for bringing a horse in. The horseback safaris guide covers how riding in this landscape differs from Laikipia, and hiking and forest walks cover the walking.

Conservation Fees for Chyulu Hills National Park

Chyulu Hills sits in the special interest band of the Kenya Wildlife Service conservation fee schedule, the lowest band the service operates. Rates are per person per day and the figures below were checked against the Kenya Wildlife Service published schedule on 21 September 2026.

Vehicles are charged separately by seat band, and camping is charged per person per night at the rate for parks outside the premium group. Private horses carry a daily charge per horse, excluding the rider, and helicopter landings in the park carry a charge of USD 300. All of these come from the same published schedule, checked on the same date.

Kenya Wildlife Service publishes no area figure for this park on its own page, and the figures in circulation disagree sharply. The world database on protected areas reports 471 square kilometres; other sources give 741 and 870. No single figure is quoted here because none of them can be traced to the managing authority.

Getting to the Chyulu Hills

From Nairobi the turning is at Kibwezi on the Mombasa road, from which a signposted road runs about nine kilometres to Kithasyo Gate and the park headquarters. The park is also reachable from Tsavo West, which is how most safari itineraries arrive. There are two airstrips, Mukururo and Kithasyo.

Tracks inside the park need a four wheel drive with clearance in any season: dust in the dry months, mud after rain. This is not a park to attempt in a saloon car, and it is not a park with the dense track network of Tsavo or Amboseli. Self-drive safaris covers what that means in practice.

Where the Chyulu Hills Fit in a Southern Kenya Trip

The Chyulus sit between two of Kenya’s best known parks and are almost always visited as an addition to them rather than alone. The standard southern circuit runs Amboseli, then Tsavo West through Chyulu Gate, then Tsavo East and out to the coast, and the hills slot in as an extra night for travellers who want ridge walking, riding or forest birding rather than another day of game drives.

They pair particularly well with Tsavo West, because seeing the hills that feed Mzima and then seeing the springs themselves makes sense of both. The group ranches on the Amboseli side of the range carry their own conservation programmes and their own lodges, and much of the riding and walking in this landscape happens on that community land rather than inside the park boundary.
