The Great Migration is a continuous ecosystem movement, not a fixed event that happens on the same date every year. Rainfall and grazing conditions influence where herds concentrate.
Southern plains
During the greener months, large numbers of wildebeest often use the Ndutu and southern Serengeti short-grass plains. This period is associated with calving and strong predator activity.
Western movement
As conditions dry, herds generally begin moving through central and western areas. Routes can spread widely, so accommodation should be positioned with realistic daily driving distances in mind.
Northern Serengeti
Later in the dry season, many herds reach the northern Serengeti and Mara River region. River crossings are dramatic but unpredictable; no operator can schedule a crossing for a specific hour or day.
Return south
After seasonal rains begin, movement gradually turns back through the ecosystem toward the southern plains.
Planning well
Choose the Serengeti sector first, then choose camp location. A migration safari is stronger when it gives multiple days in the relevant zone instead of attempting a single rushed visit.
