With thick riverine forests, acacia and palm groves, Samburu National Reserve is one of the two areas made famous in the book entitled "Born Free". The park is a lowland area and is not visited by very many tourists, making it a peaceful and serene setting for great game drives. The Ewaso Ngiro river is one of the main locations, as it is the main water source for the majority of the animal species in this otherwise arid and dry park. The Samburu National Reserve was made famous by a lioness who had adopted oryx calves. Many of the game species of the Northern Kenyan wilderness can be seen in Samburu’s habitat. Apart from the three big cats, namely Leopards, East African Lions and the Tanzanian Cheetah, Samburu is home to the Gerenuk, Reticulated Giraffe, Oryx and the Grevy’s Zebra. The park also hosts a large array of bird species, including the Secretary bird and various vultures. The river banks are ideal for spotting crocodile populations and herds of elephants, as well.
