More than one million migrating wildebeest trek across Serengeti National Park yearly in one of the wildlife spectacles of the world. Not far away in Olduvai Gorge, a German entomologist looking for butterflies found an ancient horse bone which led to the Leakeys’ discovery of Lucy and some of the world’s oldest human remains.

Tanzania is a land of superlatives. It is the size of Texas and France combined. Wildlife reserves cover over 95,000 square miles (250,000 km2), and protected areas make up about 30 percent of the country. 

They range from the vast SERENGETI in the north, with more than two million grazing animals, to the wild, remote SELOUS in the south, twice the size of Denmark, believed to hold the largest concentration of elephants, crocodiles, hippos, and endangered black rhinoceros anywhere.
