Cherangani Hills

The Cherangani Hills are a long chain of forested ridges on the western wall of the Rift Valley, north of Iten and above the Kerio Valley. They are one of the five main water towers of Kenya, they carry some of the least-visited walking country in East Africa, and almost nobody goes there.

There is no park gate, no lodge circuit and no signposted trail network. What there is instead is indigenous forest, moorland, a long ridge line and communities who farm its lower slopes.

Where the Cherangani Hills Are

Nature Kenya describes the hills as traversing three counties, Elgeyo Marakwet, Trans Nzoia and West Pokot, on the western ridge of the Rift Valley, with undulating terrain of steep hills and a series of expansive indigenous forests, savanna and grassland habitats. The Key Biodiversity Area factsheet gives an altitude range of 2,000 to 3,365 metres and puts the highest point, Cheptoket Peak, at 3,365 metres in the north-central section, across a total area of 1,050.49 square kilometres.

The forest itself is gazetted in 13 administrative blocks totalling 95,600 hectares, of which around 60,500 hectares is closed-canopy forest. The remainder is bamboo, scrub, rock, grassland, moorland and heath, with some 4,000 hectares under cultivation and plantation.

A figure to be careful with. The altitude of the highest peak is published in two versions, 3,365 metres and 3,530 metres, and they circulate side by side. This page uses 3,365 metres because that is what the Key Biodiversity Area factsheet gives, tied to a named peak and an altitude range. Anyone quoting the higher number should say where it came from.

One of Kenya’s Five Water Towers

The reason the Cherangani matter to Kenya far beyond their own counties is water. Nature Kenya records the hills as one of Kenya’s five main water towers, holding the headwaters of the Kerio and the Turkwel, which drain into Lake Turkana, and of the Nzoia, which drains into Lake Victoria. The watershed runs along the ridge, so a stream’s destination is decided by which side of a footpath it starts on.

Those same streams feed the Marakwet furrow irrigation system on the escarpment below, which Kenya placed on its World Heritage tentative list in 2023 and which extends onto the northern slopes of the Cherangani plateau in West Pokot. The hills and the furrows are one system, and understanding either properly means seeing both.

The forest is under real pressure. Nature Kenya names illegal logging, charcoal production, encroachment and clearing for agriculture, alongside overgrazing, land fragmentation, soil erosion, human and wildlife conflict and frequent fires. Community conservation work continues on the ground, including through the Chebororwa Sekemiat Site Support Group, which runs tree planting, biodiversity monitoring and environmental education.

Walking the Cherangani

This is walking country rather than driving country, and it is the main reason to come. The ridge line carries a series of named peaks, the going is open above the forest, and the views run west over Trans Nzoia and east into the Kerio Valley. It is high enough to be genuinely cold and exposed, and low enough that no technical skill or altitude acclimatisation is needed.

Trekking here is arranged locally rather than through a park authority. Routes cross community land, forest reserve and farmland, so a local guide is not an optional extra but the means by which permission, navigation and somewhere to sleep all happen. Multi-day traverses with homestays and camping are the usual format for anyone going deep, and single days out from the road are perfectly rewarding for anyone not. The general subject sits under hiking in Kenya and, for the forest blocks lower down, forest walks in Kenya.

Wildlife, Birds and Forest

The Cherangani form part of the Eastern Afromontane Biodiversity Hotspot, and their value is botanical and ornithological rather than in large mammals. Nature Kenya names two threatened plants in particular: the endangered giant groundsel Dendrosenecio cheranganiensis, which carries the range’s name, and the near-threatened parasol tree Polyscias kikuyuensis.

Among the animals it names De Brazza’s monkey, the near-threatened crowned eagle and, for the lucky, the lammergeier or bearded vulture. The Key Biodiversity Area listing adds Glaucidium tephronotum, Campephaga quiscalina and Indicator conirostris among the species of interest. For birders working western Kenya this is a serious stop and a quiet one; see birdwatching in Kenya.

Getting There and Access

The two practical gateways are Kitale to the west and Eldoret to the south, both reachable by road and Eldoret by air from Nairobi. From either, local transport runs up into the smaller escarpment towns, and that is where trekking is arranged. The hills also connect naturally with Mount Elgon and Saiwa Swamp to the west and with Iten and the Kerio Valley to the south, which is how most itineraries take them in.

The Cherangani are forest reserve and community land rather than a national park. They do not appear in the Kenya Wildlife Service conservation fee schedule and there is no park entry band that applies. Any charges are set by the forest authority or by the communities whose land a route crosses, and are arranged locally.

When to Visit the Cherangani Hills

The drier stretches, roughly June to early October and January to February, give firmer ground and better views, and are much the easier time to walk. The long rains from mid-March into June and the short rains from October into December turn the forest tracks heavy and the ridges into cloud.

Whatever the month, this is cold country. Warm and genuinely waterproof layers are needed at any time of year, and nights above 3,000 metres are near freezing. Visitors who pack for equatorial Kenya rather than for a mountain regret it.
