Lake Nakuru National Park is one of the smallest parks and the most beautiful park in the country. Lake Nakuru, a shallow, alkaline lake, occupies a third of the park. The blue-green algae flourish in the alkaline water of the lake forming the primary food source for the flamingo. The park is best known for its one and half million of greater and lesser flamingos, which is a third of the entire world population. Four hundred other species of birds have been recorded here.
