The Serengeti ecosystem is a geographical region in North-Western Tanzania hosts the largest and longest overland migration in the world.
The Serengeti contains several national parks and game reserves and is the best place in the world to go on Safari and to spot the 'Big 5', over 70 species of larger mammal and over 500 species of smaller species.
Each October nearly 2 million herbivores travel from the northern hills toward the southern plains, crossing the Mara River, in pursuit of the rains. In April, they then return to the north through the west, once again crossing the Mara River.
The area is also home to Masaii herders, known to be fierce warriors, who have farmed the land for centuries as well as the Ngorongoro crater.
