Samburu National Reserve is situated within the Northern part of Kenya approximately 350kms from Nairobi. It is relatively small in size compared to other Kenyan parks, such as Tsavo or Masai Mara. Samburu national reserve derives its name from the Samburu people of Kenya who have lived in the area for many years. The Uaso Nyiro River cuts through this reserve, drawing a big population of Kenya animals to the park. The river bustles with activity from its huge population of Nile crocodile. The reserve's topography is mainly open savannah (grassland) with clusters of acacia trees, forest, thorn trees and grassland vegetation. Samburu National Reserve was one of the two areas in which conservationists George and Joy Adamson raised Elsa the Lioness. Their story was made famous by the bestselling book and award-winning movie "Born Free”. The game reserve is renowned for its rare species of animals unique to the park, namely: the long necked gerenuk, Grevy's zebra, reticulated giraffe and Beisa onyx. The elusive Kenya leopard is often known to visit the park, especially in the evenings. Other Kenyan wildlife present in the park includes cheetahs and lions, as well as elephants, buffalo and hippos. Birdlife is as plentiful as wildlife at Samburu National Reserve, which boasts over 350 different species of birds including vultures, kingfishers, marabous, bateleurs, guinea fowl, Somali ostriches and others.
