A Living Landscape

A Journey Without a Finish Line.

Each year, vast herds of wildebeest, joined by zebra and gazelle, move through the Serengeti–Mara ecosystem, which reaches from northern Tanzania into Kenya’s Maasai Mara, in search of fresh grazing and water. There is no single place or date to see it: the migration is a continuous cycle, shaped by the rains and different every year.

As new grass follows the rain and then dries out, the herds shift between the southern plains, the western corridors and the north. River crossings happen along the way, but they are natural events — no one can say when, or whether, a crossing will take place on a given day.

The Migration Year

How the Herds Move.

A general pattern rather than a timetable: the herds respond to rainfall, and no two years are quite the same.

  1. Southern Plains

    Early in the year, the herds often gather on the short-grass plains of the southern Serengeti and the Ngorongoro Conservation Area, where many calves are born.

  2. Moving West & North

    As the plains dry, the herds typically begin moving through the central and western Serengeti in search of grazing.

  3. River Crossings

    Later in the year, the northern Serengeti is known for crossings of the Mara River. They are natural events: their timing and frequency cannot be scheduled or predicted.

  4. The Return South

    With the arrival of the short rains, the herds usually drift back towards the southern plains, and the cycle begins again.

When to Go

Planning Around the Seasons.

Because the herds follow the rain, their position shifts from year to year. Rather than chasing a fixed date, it helps to choose the time of year and the area of the Serengeti that match what interests you most — calving on the southern plains, the herds on the move, or the northern rivers where crossings may occur.

Wildlife movements are natural and can never be guaranteed, but thoughtful timing gives you a better chance of being in the right area.
