Plan your migration safari

A month-by-month guide to the Great Wildebeest Migration

Every year, the Great Wildebeest Migration unfolds across the vast expanse of Tanzania's Greater Serengeti and Kenya's Masai Mara National Reserve. This natural phenomenon involves approximately 2-million wildebeest, zebra, and other antelope on a clockwise journey from the Southern Serengeti to the Masai Mara and back.

Driven by the quest for optimal grazing grounds, many animals perish due to hunger, exhaustion, and predation by lions, leopards, and other carnivores. Rivers filled with hungry crocodiles pose additional challenges, leading to an estimated 250,000 wildebeest deaths annually. Despite its dangers, the Great Wildebeest Migration remains one of the most dramatic safari experiences and lives up to its nickname of "the greatest show on Earth".


It's important to remember that the migration isn't a singular event but a continuous cycle that's entirely dependent on rainfall patterns. Although timing can be unpredictable, past observations provide insight for planning optimal safari experiences, so here is a general "rule of thumb" rundown of the migration month-by-month, to help you understand this incredible natural phenomenon and the best times to travel.


January - February


During January and February, the majority of the herd congregates on the Ndutu Plains within Tanzania's Ngorongoro Conservation Area. Here, they graze on nutrient-rich grasses and give birth to nearly 500,000 wildebeest calves. At its peak, during this time some 8,000 calves are born each day and witnessing births and predator activity is most prevalent during this period. However, if rainfall has been insufficient, the herds may scatter in search of better grazing.


March - May


As March arrives, the herds continue grazing in Ndutu and the Southern Serengeti, with calves gaining strength for the northward migration. By April, they begin to move through the Moru Kopjes and Seronera areas. May sees the migration progressing north-westward through the Central Serengeti toward the Western Corridor, coinciding with East Africa's long rainy season and sometimes challenging conditions.


June - July


In June, the herds arrive in the Western Corridor and Grumeti Game Reserve, preparing for the perilous Grumeti River crossings. Mating season courtships and rivalries ensue, leading to heightened predator activity. By late June, the herd braves the river's currents and crocodiles. Witnessing this spectacle showcases nature's raw power.


August - October


Throughout August, the herds traverse the Northern Serengeti and Kenya's Mara Triangle, crossing the Mara and Talek Rivers multiple times in search of optimal grazing. The lack of a single crossing point adds to the challenge of predicting their movements. By September, the majority of the herd arrives in the Masai Mara, marking the peak season for witnessing the migration in Kenya.


November - December


As November brings the short rains to the Southern Serengeti, the herds begin migrating southward, starting in the Northern Serengeti and progressing to the eastern regions. By December's end, the majority return to the Southern Serengeti and Ndutu Plains, ready to commence the cycle anew. 

The art of building a northern circuit itinerary

August 3, 2026
Tanzania's northern circuit is one of the most celebrated safari destinations on earth, and with very good reason. Within a relatively compact geographic area it contains some of the greatest wildlife spectacles, most dramatic landscapes and most extraordinary natural history that Africa has to offer.

The partners who make it possible

August 3, 2026
A safari is only as good as the sum of its parts, and the parts that matter most are the ones that guests experience directly. The camp where they sleep, the food they eat, the guide who takes them out at dawn, the light aircraft that lifts them over the Serengeti and sets them down in the middle of it.

Culinary magic in the middle of nowhere

July 22, 2026
Safaris in Tanzania are usually booked for the incredible wildlife and spectacular landscapes and all that goes with them. Food is, at best, an afterthought in the planning conversation, and this is entirely understandable.

Birding in Tanzania - all you need to know

July 22, 2026
East Africa has been quietly accumulating one of the planet's most extraordinary concentrations of birdlife for millennia, and the numbers alone are enough to stop a serious birder in their tracks. More than 1,400 species across the region.

The art of pacing

June 17, 2026
Slowing down is the best decision your clients will never know you made for them. Why? Because there's a particular kind of exhaustion that safari veterans recognise immediately and first-time travellers rarely anticipate.

The experiences that make a safari unforgettable

June 17, 2026
Ask any seasoned safari traveller which moment they remember most vividly, and the answer is rarely what you'd expect. It's almost never the biggest sighting or the most dramatic crossing. More often it's something quieter, more personal and altogether less predictable than anything an itinerary could guarantee.

Our guide to chimpanzee tracking in East Africa

May 25, 2026
You hear them before you see them. Somewhere in the canopy above, something is moving fast through the branches, and then the forest erupts: a chorus of whoops and screams and the deep, resonant drumming of fists on a tree trunk that carries half a kilometre through the undergrowth and stops every conversation dead.

On the trail of the leopard

May 25, 2026
Of all the animals that define an East African safari, the leopard is the one that most consistently refuses to cooperate. Lions sleep in full view on termite mounds and pride themselves, quite literally, on being seen.

The light that changes everything

April 26, 2026
There are places in the world that are merely beautiful, and there are places that seem to exist in a state of permanent, almost aggressive photographic perfection. East Africa is firmly in the second category. Anyone who has ever raised a camera in the Serengeti at first light.

The evolution of the luxury safari

April 23, 2026
There was a time, not so very long ago, when roughing it was simply part of the deal. You went on safari, you slept under canvas, you ate whatever the camp cook produced on a gas ring and you were profoundly grateful for the experience regardless of the thread count of your sheets, largely because there weren't any.
