Tanzania Wildebeest Migration: The Complete Guide to the Great Serengeti Migration
The Tanzania Wildebeest Migration, also known as the Great Serengeti Migration, is one of the most spectacular wildlife events on Earth. Each year, over 1.5 million wildebeest, accompanied by hundreds of thousands of zebras and gazelles, move across the Serengeti ecosystem in a continuous search for fresh grazing and water.
This natural phenomenon takes place primarily in Serengeti National Park, Tanzania, and forms part of a larger ecosystem that extends into Kenya’s Maasai Mara. The migration is driven by rainfall patterns and is a year-round cycle rather than a single event.
