Amboseli National Park: 392 km² at the foot of Kilimanjaro

How big is Amboseli National Park?

Amboseli covers 392 square kilometres, the figure in KWS's February 2026 fact sheet, its 2020 to 2030 management plan and the world database of protected areas. Older KWS pages gave 390.26 km², and the 1971 presidential decree that set the park aside spoke of about 390. It lies in Loitokitok sub-county of Kajiado County, about 240 km south-east of Nairobi, and at its closest point it is 5 km from the Tanzanian border.

Inside that small area run 214 km of roads, of which 53 km are classified routes and the rest viewing tracks. The park airstrip sits at about 1,145 m, so 'about 1,150 m' is a fair altitude for the whole basin. Kilimanjaro, 5,895 m, stands across the border in Tanzania; KWS calls Amboseli the 'Courtyard of Kilimanjaro'.

When Amboseli became a national park

The park was set up in stages. Amboseli is what remains of a far larger colonial Southern Game Reserve, which KWS's plan dates to 1906, though sources give years from 1899 to 1911. In 1948 a 3,260 km² block became Amboseli National Reserve, and in 1961 it passed to the Kajiado County Council as a game reserve. A presidential decree in 1971 set aside about 390 km² for wildlife, the boundaries were demarcated in 1972, Legal Notice No. 160 of 7 August 1973 established the park, and it was gazetted on 1 November 1974 under Legal Notice No. 267.

The 162-hectare Ol Tukai enclave in the centre, where the lodges stand, was never handed over and still belongs to Kajiado County. Since 1976 the park has been run by the wildlife department that became KWS. UNESCO listed the wider ecosystem as a Biosphere Reserve in 1991, Kenya's fifth. Amboseli has been on Kenya's World Heritage Tentative List since 2023, which is not the same as being a World Heritage Site.

The swamps: Enkongo Narok and Longinye

KWS calls its two great swamps, Enkongo Narok and Longinye, 'the lifeline of the park's wildlife'. Water from Kilimanjaro travels underground through a series of aquifers and rises in the basin as cold, clear springs, so the swamps hold water all year in a park that gets about 350 mm of rain. A third, smaller swamp, Ol Tukai Orok, is lined with doum palms. When the plains dry out from June to October, the elephants and the plains game converge on the swamps.

Longinye has been growing. KWS's management plan records it flooding parts of the Ol Tukai enclave and closing tourist circuits, and plans to clear the old drainage channels towards Lake Amboseli. You will see 'Ol Okenya' named as a main swamp on some sites; KWS uses no such name.

Lake Amboseli: a lake bed most of the year

Lake Amboseli, on the western side of the park, is a playa of about 300 square kilometres, the remains of a far bigger Pleistocene lake. Most of the year it is a flat expanse of salt and dust, which is where the park's name comes from: the archived KWS page translates the Maasai word as 'salty dust'. After heavy rain it floods, and when it does it draws flamingos.

The flooding has become more frequent. KWS notes that until 1992 the basin did not flood as it now does, and in December 2019 floods closed viewing roads and the airstrip. So do not count on water: the lake bed may hold some after the long rains in April and May and after heavy short rains in December, and is dry for the rest of the year.

Observation Hill

Observation Hill, Nomatior in Maa, 'the place of pottery', is the highest point in the park and the one place KWS lets visitors leave their vehicle, walk and picnic. From the top you look over the Enkongo Narok swamp and the small lake below it, where hippos keep to the reeds. KWS ties the hill's cultural history to the Ndorobo community.

It is not a secret. KWS's management plan says at least 80 per cent of the park's visitors stop here, and it is the only place tour operators bring guests to rest and eat after a game drive, so it has steps, shade, information boards and washrooms.

The conservancies around the park

Most of Amboseli's large mammals depend on the land around it: they disperse onto the surrounding group ranches in the wet season, and the elephants range over about 8,000 km². The UNESCO biosphere reserve treats the park as its core and six Maasai group ranches as the buffer: Olgulului-Ololarashi, Eselenkei, Mbirikani, Kimana, Kuku and Rombo. Olgulului-Ololarashi, which surrounds the park on most sides, has set aside the Ilngarunyoni, Kitirua, Ole Narika and Kitenden conservancies to link the park with the rest of the ecosystem.

On the east side lie the Kimana Community Wildlife Sanctuary and the Osupuko, Nailepu and Kilitome conservancies, joined to the park by the Kimana Corridor, which Big Life says is just 46 metres wide at its narrowest. North of the park, the 12,500-acre Selenkay Conservancy is leased from the Maasai by the operator of Porini Amboseli. These conservancies are where walking safaris and night drives happen, because inside the park you stay in the vehicle.

Who runs Amboseli: the Kajiado County dispute

A deed transferring management of the park from the national government to Kajiado County was signed on 14 October 2025, but the High Court suspended it with conservatory orders on 30 December 2025 in Constitutional Petition E737 of 2025. In July 2026 the court restrained the county from taking over the park, and the substantive hearing was set for 5 October 2026, while KWS kept running the gates and collecting the fees.

This may have moved after 4 October 2026, the day we last checked.
