The Samburu National Reserve is a game reserve on the banks of the Ewaso Ng'iro river in Kenya. On the other side of the river is the Buffalo Springs National Reserve. The park is 165 km² in size and is situated 350 kilometers from Nairobi. It ranges in altitude from 800 to 1230 m above sea level. Geographically, it is located in Samburu County.
In the middle of the reserve, the Ewaso Ng'iro flows through doum palm groves and thick riverine forests. It provides water, without which the game in this arid region could not survive.
