Masai Mara National Reserve is a world-famous wildlife reserve in southwest Kenya, known for its vast savannah, abundant wildlife including the "Big Five" (lion, leopard, elephant, buffalo, rhino), and the spectacular annual Great Migration of wildebeest and zebra. Part of the larger Mara-Serengeti ecosystem, the park is named after the Maasai people and their word "Mara," meaning "spotted," for the landscape's many trees and bushes.
