The wildebeest migration on the move

The Great Migration

The great migration is roughly two million wildebeest, zebra and gazelle moving clockwise through the Serengeti and Masai Mara ecosystem in a continuous annual loop, following rainfall and grass. It never stops and it is never in one place. The only real question when planning is where the herds will be in the month you can travel, and which lodge that puts you in.

The river crossings that dominate the photographs are one part of the circuit, in the north, from roughly July to October. They are dramatic, they are unpredictable, and a herd can stand at the bank for six hours and then decide not to go. Building a whole trip around seeing one is how people come home disappointed.

The calving season in the southern Serengeti in February is, for many guides, the better trip. Hundreds of thousands of calves are born within a few weeks on open short-grass plains, every predator in the ecosystem is drawn to them, and the sightlines are far better than in the northern woodland.

Where the herds are, month by month

MonthsRoughly whereWhat is happening
December to MarchSouthern Serengeti and Ndutu, Ngorongoro conservation areaShort-grass plains, calving peaking in February, heavy predator action
April to MayCentral and western SerengetiLong rains, herds moving north and west, lodges at their cheapest
June to JulyWestern corridor and the Grumeti riverColumns forming, Grumeti crossings, large crocodile
July to OctoberNorthern Serengeti and the Masai MaraMara river crossings, both directions, entirely unpredictable
NovemberMoving south through the eastern SerengetiShort rains pull the herds back down towards the plains

Treat this as a pattern rather than a timetable. The herds follow rain, rain varies year to year, and a dry March can hold them south for weeks longer than the table suggests.

How to actually see a river crossing

Be in the north between late July and early October, stay at least four nights, and accept that you will spend hours parked at a bank. Crossing points on the Mara river are known and your guide will position for one, but the herd decides. Groups that stay two nights and leave often see nothing; groups that stay five usually see at least one.

The Mara triangle on the Kenyan side and the Kogatende area of the northern Serengeti both work. The triangle has fewer vehicles than the Mara reserve’s eastern side. Whichever side you choose, a private conservancy alongside it gives you somewhere productive to be on the days the herds do not move.

Why February is underrated

  • The calving is concentrated in a few weeks and happens in the open
  • Short grass means you see the hunt from the beginning, not the end
  • Cheetah in particular are far easier to find on the Ndutu plains
  • It is outside the northern high season, so camps are easier to get

What we do not promise

Nobody can guarantee you a river crossing, and any operator who does is selling you something they do not control. What we can do is put you in the right part of the ecosystem for your dates, in a camp positioned for it, with enough nights to make it likely, and with a guide in radio contact with the vehicles already at the bank.

Mobile camps

The camps that move with the herds are the ones worth booking. A mobile tented camp relocates two or three times a year to stay with the migration, which means it is genuinely in front of the animals rather than a two-hour drive from them. They are simpler than a permanent lodge, with bucket showers and no pool, and they are the better trip.
