Nowhere says Africa like the Rift Valley, with its savanna, geology, fauna and history as the cradle of human life. In Kenya, the Rift's steep sides and wide plains are at their most dramatic and there are few better views than those found about an hour outside Nairobi, when the road to Nakuru suddenly crests the valley's eastern edge and plunges thousands of feet to the floor. On a clear day you can see for hundreds of miles, right down to Tanzania.
