The Aberdare National Park in central Kenya — 766 sq km of high-altitude moorland, bamboo forest, and Afro-Alpine heath at 2,000–4,001 m elevation in the Aberdare Range (the Kikuyu Escarpment) — is most famous for two things that have nothing to do with each other: the extraordinary tree hotel concept (The Ark and Treetops — lodges built above a floodlit waterhole in the forest, where wildlife comes to the visitor rather than the visitor going to the wildlife), and the presence of the bongo (Tragelaphus eurycerus isaaci — the largest and most beautiful of Africa’s forest antelope, a deep chestnut-coloured spiral-horned antelope found in Kenya only in the Aberdares and on Mount Kenya). Both are genuinely exceptional experiences that put the Aberdares on any comprehensive Kenya itinerary. This guide covers the Aberdares for 2025.
The Tree Hotels: The Ark and Treetops
The concept of the Kenya tree hotel — accommodation elevated above a forest waterhole where wildlife comes to the mineral lick and salt supply throughout the night, observed from viewing platforms and interior windows — was pioneered at Treetops (where Princess Elizabeth was staying when she became Queen Elizabeth II in 1952, on the news of her father’s death — the most famous coincidence in Aberdares tourism history). The Ark (deeper in the Aberdare forest, at the Salient area, more remote than Treetops): a 4-storey wooden lodge overlooking a large waterhole and salt lick, 32 rooms, with a ground-level “bunker” viewing position for nocturnal wildlife at 2 m above the waterhole. The Ark’s night wildlife programme: buffalo (large herds, 50–100 individuals, use the waterhole throughout the night), elephant (regularly visiting the salt lick area), giant forest hog (the world’s largest pig species, Hylochoerus meinertzhageni — a forest specialist seen at The Ark and few other accessible locations in East Africa), black-and-white colobus (in the surrounding trees), and the occasional leopard or side-striped jackal. A UWA ranger stays on night watch and alerts guests via room buzzer when lion, leopard, rhino, or other key species arrive.
The Bongo
The mountain bongo (Tragelaphus eurycerus isaaci) — 250–300 individuals in the wild in the Aberdares and Mount Kenya forests, Critically Endangered — is one of Africa’s rarest large mammals and one of Kenya’s most sought wildlife species. The bongo’s appearance: deep chestnut to orange body with 10–15 white vertical stripes, a white chevron between the eyes, white leg markings, and long spiral horns (both sexes are horned, unlike most bovids) — arguably Africa’s most beautifully patterned large antelope. Bongo sightings in the Aberdares: the animals use the forest-edge clearings adjacent to bamboo at 2,200–3,000 m altitude, most often seen early morning or late afternoon at the open grassland patches visible from the Aberdare high-altitude road. The waterhole at The Ark is one of the more reliable bongo observation points in the Aberdares — the salt lick attracts bongo at irregular intervals, and The Ark’s night staff maintains sighting records that allow guests to calibrate their expectations for any given night.
Waterfall Hikes
The Aberdares are home to several of Kenya’s most spectacular waterfalls: Gura Falls (300 m — the highest waterfall in Kenya, in a remote section of the Aberdares requiring a guide and a full-day walk), Karuru Falls (275 m, a 3-tier cascade accessible on a 4-hour hike from the Ruhuruini area), and the Chania Falls (40 m, the most accessible — 30 minutes walk from the Aberdare Country Club gate). The Aberdare waterfall hikes require a KWS ranger guide (arranged at any park gate, USD $15–25/group) and appropriate footwear for the moorland trails. Entry: USD $35/person/day (Aberdares is one of Kenya’s cheaper major parks). Tree hotel accommodation: The Ark USD $200–300/night per person all-inclusive (booked through Aberdare Country Club); Treetops USD $150–250/night all-inclusive.
