The Great Migration is a continuous search for fresh grass and water by roughly two million wildebeest, zebra and gazelle. The animals do not follow our calendars, but years of observation reveal a broad seasonal pattern.
January through March is calving season on the short-grass plains of the southern Serengeti and Ndutu. April and May bring long rains and movement northwest. From June the herds approach the western corridor, while July through October is associated with the northern Serengeti and Maasai Mara river systems.
November’s short rains often draw the herds south again. River crossings may happen repeatedly, suddenly or not at all on a given day. The strongest trips build in time and use excellent guides rather than treating one dramatic moment as a guarantee.
