Complete month-by-month Great Migration calendar for 2026-2027. Know exactly where the wildebeest herds will be and when to witness river crossings.
The Great Migration is Earth most spectacular wildlife event, with over 1.5 million wildebeest, 200,000 zebras, and 500,000 gazelles making their annual circuit through the Serengeti-Mara ecosystem. This guide provides a detailed month-by-month breakdown for 2026 and 2027, based on our 20+ years of tracking migration patterns.
