The Great Migration: When to Go and Where to Be

The Great Migration is the largest overland movement of animals on earth — 1.5 million wildebeest, 200,000 zebra and 300,000 Thomson's gazelle moving in a continuous loop between Tanzania's Serengeti and Kenya's Maasai Mara. Here is what nobody tells you: it is never guaranteed. The crossing dates shift by weeks depending on rainfall. The herds do not read calendars. What we can tell you is where to be, and when to be patient.
