Wildebeest Migration – An Epic Journey

Share this article

The wildebeest migration is an ever-moving circular journey of over a million wildebeest, zebra and gazelle across the Serengeti-Mara ecosystem annually. It is one of the most sought-after wildlife experiences by thousands of travelers on safari in Africa especially around mid-year. 

In this continuous movement, columns of wildebeest accompanied by a host of zebras and Thomson’s gazelle follow an age-old route through Tanzania and Kenya in search of fresh grazing. The migraters dare traverse the dangerous predator-infested territories to catch up with the seasonal rains.

After calving, which occurs in the Ndutu plains south of Serengeti near the Ngorongoro Conservation Area around January and February, the wildebeest start to travel through the Serengeti up and around in a clockwise direction towards the Masai Mara before returning again towards the end of the year. Following on their heels are the predators of the savannah as thousands of migrating ungulates are taken while thousands more are born, replenishing the numbers and sustaining the circle of life.

While timing is absolutely important to witness this wondrous event, there’s no way to predict the movement of the animals. We are aware that the rains will cause the animals to move on to fresh grazing, but the exact timing of the ungulates crossing the Mara River is unknown. Again, nobody knows exactly when the rain will fall.

Fortunately, we’ve been planning Wildebeest Migration safaris in Africa and have helped many travelers be in the best possible place at the right time. This practical beginner’s guide to a wildebeest migration safari offers expert advice as you will understand what exactly the migration is, where, how, and when it occurs, and the best time to witness the events.

What is the Wildebeest Migration?

What is the wildebeest migration? It is the yearly movement of over one million wildebeests, zebras, and Thomson’s gazelles from northern Serengeti to Masai Mara in search of nutritious grass. With up to a thousand animals per square kilometre, the great columns of wildebeests and gazelles can be seen from space. 

Every single wildebeest covers long distances of about 800 to 1,000 kilometres on its individual journey along the age-old migration routes guided by survival instinct. In this pursuit for life, hungry predators such as lions, cheetahs, leopards, wild dogs, hyenas, and crocodiles ensure that only the strong survive.

How the wildebeests know which way to go still remains a mystery. However, a general consensus supposes that their journey is dictated primarily by their natural instincts—their ability to respond to the weather. This is seen in their ability to follow the rains and the growth of new grass more than 50 kilometres away.

Why do Wildebeest Migrate from Tanzania to Kenya?

Why do wildebeests migrate? Because they are following the rains and the growth of fresh pasture to stay alive. The grasses of the entire Serengeti-Mara ecosystem contain the highest quantities of calcium and protein, which also support the growth of their calves.

With different grass eating habits, one group of the migrant grazers consumes the top of the tallest grass, and the following group will begin to consume some of the medium-height grass. This behaviour continues until the grass is almost completely consumed, at which point the herds move on.

What Month is the Wildebeest Migration?

The river crossings at Mara River normally coincide with the peak or high season from June to August or early September and again from the last two weeks of October through early November on their return southwards. This is the best time to track and see the wildebeest migration river crossings in Masai Mara.

Although most people think that this is the only time of the year that the wildebeests are on the move or can be seen, the migration is an ever-moving, circular movement with various but equally exciting events all year-round.

How does the Great Migration move throughout the year?

The wildebeests move from the south of the Serengeti plains northwards and around in a clockwise direction towards Masai Mara in Kenya, and then return once again towards the end of the year. It all begins after calving in the south of Serengeti, near the Ngorongoro Conservation Area. They will move in search of nutritious grass for their new-born calves to support their growth.

Month-by-month Wildebeest Migration

July to November is considered the best time to see the wildebeest migration. Between July and August, wildebeest herds move and mass in Kenya’s Maasai Mara, crossing the Mara River in overwhelming numbers. River crossings are the most sought-after episodes of the wildebeest Migration.

The long and short rainy seasons in Tanzania and Kenya are no longer as regular or predictable as they once were. This change in climate and different weather patterns are responsible for determining these animal movements. 

The rain can come late or early, regardless, it’s important for travelers to plan for as much time as possible. For instance, you cannot fly in for just two or three nights, witness a river crossing, and fly out again; nature simply doesn’t work that way. This guide will therefore help you plan a thrilling wildebeest migration as presented by the months:

January 

The herds are moving south from Serengeti National Park in the north-east region of Tanzania into the area close to Lake Ndutu. They are free to roam the plains of the Serengeti, where they can find grazing since it’s not a fenced area.

Keep in mind that despite the Serengeti Migration consisting of up to two million wildebeest, zebra, and antelope, they are not all congregated in one herd. Mega-herds of thousands or hundreds of animals separate and disperse across the plains.

February to March

This is the calving season, with an estimated 8,000 or more wildebeest calves born each day (400,000 calves within a period of two to three weeks)! So, get ready for lots of shaky calves and heartbreak as terrifying predators close in.

Despite the fact that this migratory circuit has no actual beginning or finish other than birth and death, it seems logical to refer to the wildebeests’ birthing season as the migration’s beginning.

In late January or early February, the vast herds move into the short-grass savannah plains surrounding Olduvai Gorge and the lower northern slopes of the Ngorongoro Crater highlands.

Big cats dominate the Serengeti, but jackals that hit-and-run, hyena clans, and wild dog packs also contribute to the display. The circle of life played out as a live-action drama is a bittersweet ballad to witness.

The herds feed agitatedly and remain on the southern plains of the Serengeti if the brief wet season between November and December yields excellent grazing until they slowly begin moving west in March.

April

The long rains start in April or May, and the vast herds generally move north-west towards the Moru and Simba Kopjes. At the same time, it is the breeding season associated with testosterone-fueled jousts between males competing for the right to mate with receptive females.

May

Wagons roll! The enormous herds begin moving, and as the ungulates funnel up into the center of the Serengeti, massive columns up to 40 kilometers (25 miles) in length form. The calves are picking up speed, and everyone’s moving a little quicker now.

June

The ungulates are normally staged in the central Serengeti, getting ready for the most challenging part of their odyssey. Some herds are splitting up and are already crossing the Grumeti River.

July

The ungulates have reached the Grumeti region and north Serengeti and are peering closely at the treacherous waters of the Mara River they have to cross into Kenya. Why? Notoriously huge Nile crocodiles lie in wait!

As was previously said, it is impossible to anticipate with any degree of accuracy when a river crossing will occur because it depends only on the rain and the frequently unpredictable wildebeest.

To cut down on travel time to lookout locations on your wildebeest migration safari, we recommend booking up to a year in advance to get a lodge as close to the river as possible.

Alternatively, you can choose a mobile safari camp that moves with the migration to ensure you’re in the right place at the right time. There are known crossing points for the wildebeest, and you may need to set up camp for days in order to catch a glimpse of this epic phenomenon.

August

Most people agree that August is the best month to witness the impressive river crossings from the northern Serengeti into the Masai Mara. You should, however, note that you’ll need a passport to cross into Kenya; the wildebeest are exempt. For a more private safari experience, we recommend heading for the private conservancies that are adjacent to the reserve, as Masai Mara is open to the general public.

September

Not all the wildebeest migrate into Kenya, so the herds break up into smaller groups. In the northern Serengeti, fewer than half of the animals are still present; the others are swapping war stories in the Masai Mara.

So, you could still see wildebeest in the Serengeti, although not in the vast herds. As it always is, the Masai Mara is the more convenient place to witness the migration in September.

October

The Masai Mara remains your best option, but keep in mind that it is a much smaller reserve than the Serengeti and that there can be a lot of other visitors there. You may still witness the Great Migration at the nearby private conservancies because they are far less crowded, and by doing so, you’ll be directly benefiting the Maasai communities who have lived there for generations.

The private conservancies usually offer night drives, walking safaris, and off-road game viewing—activities that are not permitted in the national reserve.

November

The beginning of the short rains has caused the wildebeest to return to the Serengeti after leaving the now-depleted grass of the Masai Mara. Remember that rain is unpredictable and may come early or late.

The herds are typically moving, but they can be spotted in the Serengeti’s north-eastern regions, where they may separate into smaller groups on their journey south.

Note: Although many people think of Africa as a hot place, the rain can significantly reduce temperatures. You’ll be out on early morning and late afternoon game drives when the sun is at its weakest. Bring at least one pair of mud-resistant closed shoes, a fleece or waterproof jacket, and at least one pair of pants.

December

The ungulates move back south for fresh grazing, covering the northern and eastern Serengeti to feast and prepare for yet another death-defying, 3 000 km (1 900 mi) annual trek.

Where does the Great Migration Start?

Where does the great migration start? Southern Serengeti. The wildebeest migration, in short, starts in Southern Serengeti from the edge of the Ngorongoro crater after calving. It is a fluid, year-round movement of about two million wildebeests, zebras, and gazelles across the Serengeti-Mara ecosystem.

This phenomenon is triggered by East Africa’s rains, and the ungulates follow an age-old route in search of fresh grazing and water. Predators are constantly on the lookout for calves, as thousands are born within a couple of weeks.

Can the Migration River Crossings be Predicted?

No, no one can – not even the wildebeests know when they’re about to cross! Some arrive at the water and start swimming immediately, while others arrive and spend days hanging around grazing; some arrive and turn back to where they came from. We wish we could predict the crossings, but it all remains a mystery. This is why we recommend spending as much time on safari as possible if you hope to see a river crossing.

When is the best time to Go on a Migration Safari?

Between July and early October, during the dry season, is the best time to see the great migration. The weather is stable and warm, and animals are abundant, but the vegetation is scarce and water sources are dried up. This forces the herds to move north to find fresh grass.

Seeing the wildebeest migration also depends entirely on which events you’re personally interested in. Between mid-July and late August will give you a thrilling experience, and to be specific, August. However, the Serengeti and Masai Mara’s abundant wildlife and savannah plains yield spectacular sightings all year-round.

Key Facts
  • It’s a circular, all-year-round journey.
  • The Serengeti hosts the majority of the migration.
  • Although they cannot be predicted, river crossings often take place between June and August.
  • There are always forerunners and stragglers among the herds, which are dispersed over a wide area.
  • Spending the entire day at a location where the wildebeest have congregated may give you the best opportunity to observe river crossings. Avid photographers have the finest possibilities around noon, when the sun and glare are at their harshest.
