Millions of years ago the earth's crust was weakened and it tore apart creating a split thousands of kilometres long down the continent of Africa, up to 62 miles (100km) wide in places. Volcanic eruptions on either side caused the floor to sink into a flat plain creating the Great Rift Valley. It is one of Kenya's characteristic features and divides the country in half, from north to south, with stunning panoramas and beautiful escarpment backdrops. The wide valley is scattered with a few volcanoes and several lakes; it is inhabited by grazing animals, Masai herders and small-town dwellers.

The string of alkaline lakes known for their stunning scenery and variety of bird life include Lakes Naivasha, Elementeita, Nakuru, Bogoria and Baringo. The uniqueness of these lakes lies in their high concentration of sodium carbonate from the surrounding volcanic rocks. This creates an ideal breeding ground for algae and a thriving environment for fish, which in turn attracts millions of birds to feed on the abundant food supply. Each of the lakes has a different water composition ranging from freshwater to very saline and brackish, with different bird life attracted to each.

The freshwater ecosystems at Lake Naivasha and Baringo, the nature reserve at Lake Bogoria, and the Nakuru National Park are a source of endless fascination, teeming with an incredible diversity of birds and large concentrations of animals. Hell's Gate National Park allows visitors to walk or cycle among the wildlife, and nearby Elsamere Conservation Centre provides a look at the life of Joy Adamson and the lioness Elsa, of 'Born Free' fame.
