The Great Migration

The eternal natural spectacle of the Serengeti

Over a million wildebeest, accompanied by hundreds of thousands of zebras and gazelles, move in an endless column through the vastness of the Serengeti. Dust swirls up, hooves thunder on the dry ground, and somewhere on the distant horizon, the golden light of the setting sun is reflected in one of the few remaining waterholes. Welcome to the Great Migration – one of the most impressive natural spectacles on our planet.

The Great Wildebeest Migration, or Great Migration, is much more than just the dramatic image of a herd crossing a river. It is a constant, never-ending cycle – driven by rain, fresh grass and the insatiable hunger of around 1.5 million animals.

“The Great Migration knows no beginning and no end. It is an eternal cycle of life, guided solely by rain and grass.”

A Steady Cycle – More Than Two Highlights

Travel magazines and nature documentaries often show only two moments of wildebeest migration: the dramatic river crossings on the Mara River and the calving season in the Ndutu Plains, on the edge of the Serengeti in the Ngorongoro Conservation Area. Both events are unquestionably unforgettable. But the great migration is not limited to these highlights.
The herds migrate 365 days a year. Every month, every week, they are somewhere on their 800 to 1,000-kilometer circular route through the Serengeti and the adjacent Maasai Mara in Kenya. The driving force: water and fresh, nutritious grass.
The animals instinctively follow the rain because only there does the young grass sprout, which provides them with the necessary nutrients. This ancient knowledge is anchored in their genetic material and has proven itself over thousands of years. Satellite data show that wildebeest can detect thunderclouds up to 50 kilometres away – and start moving immediately.

Where are the wildebeest? The seasonal calendar

Depending on the travel period, you can experience the wildebeest in completely different regions. The following overview shows the approximate course – the exact times depend on the annual rainfall:

Months	Region	Special feature
December – March	Southern Serengeti & Ngorongoro	calving period; fresh grass lures the herds
April – May	Central Serengeti (Seronera)	rainy season; the herds linger on lush meadows
May – June	Western Corridor	train heading west; First river crossing to the north on the Grumeti River
July – August	Maasai Mara, Kenya	Highlight: Mara River Crossing
September – October	Northern Serengeti & Maasai Mara	Stay in the North; continue river crossings
November	Return to the southern Serengeti	Beginning of the retreat; first short rain

This table is a guide. Nature does not stick to fixed schedules: an early rain can set the herds moving for weeks, a dry month can keep them in an area longer. This is precisely what makes migration so lively, but also unpredictable.

Highlight I: The calving season (January to March)

Southern Serengeti and Ndutu Region

Between January and March, the southern Serengeti around the Ndutu area is transformed into a huge nursery. In just a few weeks, up to 500,000 wildebeest are born – that’s about 8,000 new births per day at the peak of the season in February.

Why does survival succeed? Evolution has developed a sophisticated mechanism: almost all wildebeest give birth within 2 to 3 weeks. As a result of this “simultaneous birth”, so many calves are born that predators such as lions, cheetahs, and hyenas are simply not able to prey on all of them. The chance of survival of each calf increases dramatically.

Minutes after birth, the calves are already standing on wobbly legs. After a few hours, they can keep up with the herd.

“The calving season is one of the most emotionally intense experiences Africa has to offer – life and death in constant change, embedded in a golden-green savannah.”

Highlight II: The Mara River Crossing (July to October)

Western Corridor & Maasai Mara, Kenya

Hardly any other natural spectacle in the world attracts photographers and nature tourists as magnetically as the crossings of the Mara River. Between July and October, the herds migrate from the Serengeti to the Kenyan Maasai Mara and back again – and this forces them to cross the Mara River several times.

What follows is pure chaos and cinema: thousands of wildebeest crowd the shore, hesitate, jump, and plunge into the brown water. Nile crocodiles lurk patiently. But the power of the herd is stronger – most of them make the transition. Where, however, lions and hyenas are already waiting for the exhausted animals.

A wildebeest crosses the river an average of 4 to 8 times per season. Because grass is omnipresent and in the weeks before the move to the Maasai Mara, the animals are already wandering through the western corridor, where they have crossed the Grumeti River. The Grumeti is narrower, but there are also huge Nile crocodiles lurking here.

What makes the Crossing so special?

• The unpredictability: Nobody knows exactly when the animals jump.
• The masses: Up to 10,000 wildebeest cross in a single day.
• The predators: lions, leopards, hyenas, and crocodiles are present in large numbers.
• The emotion: life and death take place in real time – not a staging, pure nature.

“The Mara River Crossing is not a guaranteed spectacle – but when it happens, it changes you. It’s the wildest, most untamed experience the African continent has to offer.”

Between the highlights: Life doesn’t stop

If you travel between the big moments, you will experience the wildebeest migration in its quieter, but no less fascinating form:

• In April and May, the herds rest on the lush green central meadows of the Seronera region. The predator density is enormous.
• In June, the migration to the west begins – the column of wildebeest sometimes stretches for dozens of kilometers.
• In September and October, many animals still stay in the Maasai Mara before the herd turns south again.
• In November, the first short rain sets in – the wildebeest feel it and begin the long journey back to the southern Serengeti.

At no time of the year is the Serengeti empty. There is always a part of the herd somewhere on the way. The spectacle of life always takes place. The cycle is complete and uninterrupted – as it has been for thousands of years.

Travel Tips: When to Go

For the calving season: January to March, Ndutu / Southern Serengeti

For the Mara River Crossing: July to October, North of the Serengeti or Maasai Mara (Kenya)

For crowds and tranquility at the same time: April to June, Seronera and Western Corridor

No matter when you travel, the Serengeti doesn’t disappoint. She is always alive, always wild, always great.

Conclusion: The Great Migration as a symbol of life

The Great Wildebeest Migration is not an event with a fixed date in the calendar. It is a pulsating, constant rhythm of nature – as old as the savannah itself. Calving season and Mara River Crossing are the glamorous highlights of a spectacle that never stops.

What makes this migration so deeply moving is not the single moment of the drama. It is the knowledge that something primeval is happening here: millions of animals, guided by instinct alone, follow the same path as their ancestors thousands of years ago. No GPS, no signpost – just the smell of rain and the promise of fresh grass.

“The Great Migration is not a spectacle that you watch passively. It is a force that sweeps you away – and remains a part of you forever.”
