The world-renowned Masai Mara National Reserve needs little in the way of introduction. Its tawny, wildlife-stuffed savannahs are familiar to anyone who has watched nature documentaries. Reliable rains and plentiful vegetation underpin this extraordinary ecosystem and the millions of herbivores it supports. Wildebeest, zebras, impalas, elephants, Masai giraffes and several species of gazelle all call the Mara home. This vast concentration of game accounts for high predator numbers, including cheetahs, leopards and the highest lion densities in the world.
