Only 90 kms (56 miles) North West of Nairobi, at the foot of the Rift Valley Escarpment, lays Lake Naivasha. Few lakes have a more commanding or lovelier setting than this, the highest and purest of all the Rift Valley lakes. Its secluded lagoons are fringed with papyrus. Mount Longonot 2,977 m (9,109 ft) a now extinct volcano, dominates the skyline in shades of misty blues and purples. Lake Naivasha claims to be home of more species of birdlife than the whole of the British Isles. Water birds exist in great variety and abundance. Pelican, cormorant and heron are well represented and are best viewed during a boat trip on the lake, which also offers the chance to see hippo at close quarters. A notable bird is the African fish eagle which nests in the trees along the lakeshore, and whose haunting cry is heard echoing across the water. A narrow causeway links the mainland to Crescent island, a private game sanctuary, where you can walk, viewing a variety of game such as gazelle waterbuck, zebra, giraffe, bat-eared fox, and dik dik. 13 kms (8 miles) south of Lake Naivasha is the dramatic Hell's Gate Gorge - a stark passageway between red towering cliffs. It is here that the Lammergeyers nests - the rarest of Kenya's birds of prey.
