The Rift Valley lakes are a group of lakes in the East African Rift that runs north-south through the eastern side of the African continent, from Ethiopia in the north to Malawi in the south. These lakes include some of the oldest, largest, and deepest lakes in the world. Many are freshwater ecoregions of great biodiversity, while others are alkaline "soda lakes" supporting highly specialized organisms.
Masai Mara Game Reserve is Kenya's most spectacular of all Kenyan parks and reserves, and here you have the best opportunity of spotting the Big Five - lion, leopard, buffalo, rhino, and elephant. The Reserve covers an area of 700 square miles and forms part of the Serengeti ecosystem and hence hosts the world-famous spectacle of the annual migration of up to two million wildebeest, thousands of zebra, and an escort of carnivores from the Serengeti plains, following the rains and succulent new grass. April is NOT migration month but still, visitors will be able to see a large variety of wildlife in their natural habitat which is what Maasai Mara is famous for.
