Africa is truly the cradle of life. Roam the famous Serengeti National Park, nearly 15,000 sq km of rolling savanna that shelters an astounding array of animals from miniature dik-dik antelopes to lions and the noble African elephant. Spot wildlife among the ethereal vistas from atop the Ngorongoro Crater. This is also a human journey that puts you among Kenya and Tanzania's bustling markets and plantations, and in the valleys once inhabited by humankind's earliest ancestors. If you want to experience some of the most superb game-viewing in Africa, then this will truly be a tour to remember.
