Which UNESCO World Heritage Site in Tanzania is famous for the annual migration of wildebeest and zebras?

The UNESCO World Heritage Site in Tanzania famous for the annual migration of wildebeest and zebras is Serengeti National Park.

Serengeti National Park protects a vast grassland ecosystem in northern Tanzania. It was established in 1951 and forms part of a wider ecosystem that extends toward Kenya’s Maasai Mara. The park is renowned for large populations of plains animals, including wildebeest, zebras, gazelles, lions, cheetahs, and spotted hyenas.

The migration is driven by seasonal rainfall and the availability of fresh grass, so it is a moving ecological cycle rather than a single annual event with one fixed route. Serengeti is sometimes confused with the Ngorongoro Conservation Area, which is nearby and separately listed. UNESCO inscribed Serengeti National Park in 1981 for its exceptional ecological importance and wildlife concentrations.
