Every year, the plains of East Africa come alive with one of the most breathtaking natural phenomena on Earth: the Great Migration. Over 1.5 million wildebeest, accompanied by hundreds of thousands of zebras and gazelles, embark on a year-long journey through the Serengeti in Tanzania and the Maasai Mara in Kenya. This incredible spectacle is a vital process that shapes the ecosystem, sustains predator-prey dynamics, and brings visitors from around the world to witness its grandeur.
Whether you’re a seasoned adventurer or planning your first family safari, the Great Migration is an unforgettable experience that combines education, adventure, and a deep appreciation for the natural world. In this article, we’ll uncover the story of the Great Migration, explore its route, discuss why it happens, and provide travel tips to help you witness this marvel up close.
What is the Great Migration?
The Great Migration is an epic circular journey undertaken by over 1.5 million wildebeest, alongside 200,000 zebras and several hundred thousand gazelles, in search of fresh grazing lands and water. Spanning over 2,800 kilometres, it is the largest overland migration in the world and a phenomenon unique to East Africa. This journey takes place primarily across the Serengeti National Park in Tanzania and the Maasai Mara National Reserve in Kenya, creating a dynamic, year-long movement that sustains life across the savannah.
The migration is often described as the “greatest show on Earth”, not just because of the massive volumes of animals but also because of the drama that unfolds. Predators like lions, cheetahs, leopards, and crocodiles closely follow the herds, waiting for opportunities to hunt. This continuous movement of life and death shapes the very fabric of the savannah ecosystem, making the Great Migration a central pillar of life in East Africa.
Why Do They Migrate?
The Great Migration is primarily driven by the changing seasons and the herds’ need for food and water. The migration follows a predictable pattern linked to the region's rainfall cycle, which dictates where fresh grasslands will grow.
The wildebeest and their companions are constantly in search of nutrient-rich grass to sustain their vast numbers. The herds' movements ensure that no single area is overgrazed, allowing the ecosystem to regenerate. This cyclical grazing pattern not only feeds the migrating animals but also promotes plant growth, disperses seeds, and provides sustenance for predators along the way.
The journey also serves an important reproductive purpose. During the calving season, which occurs from December to March in the southern Serengeti, thousands of wildebeest calves are born. This timing ensures that the young have access to the lush, nutrient-rich grasses that grow during the rainy season, giving them the best chance to grow strong before embarking on the migration.
Despite the dangers posed by predators, river crossings, and harsh terrain, the instinct to migrate is deeply ingrained in these animals. Their collective movement is a testament to the delicate balance of nature and the interconnectedness of life on the African savannah.
The Migration Route: A Year-Long Journey
The Great Migration is a circular movement driven by the changing seasons and the quest for fresh grazing lands.
Key Stages of the Migration
-
December to March: Southern Serengeti - Calving Season
- The migration begins in the Ndutu region of the southern Serengeti, where the herds gather during the short rains.
- This is calving season, with over 500,000 wildebeest calves born within a few weeks. This abundance of young animals attracts predators, making it a thrilling yet dangerous time for the herds.
- The lush, nutrient-rich grasses provide essential nourishment for the nursing mothers and their young.
-
April to May: Central Serengeti - The Long Rains
- As the rains continue, the herds move north toward the central Serengeti. Here, they spread out across the plains, grazing on the growing grasslands.
- This period sees large groups breaking into smaller clusters, making them less vulnerable to predators.
-
June to July: Western Corridor and Grumeti River
- The herds congregate in the western Serengeti, preparing for their first major challenge: crossing the Grumeti River.
- The Grumeti River is home to some of Africa’s largest crocodiles, lying in wait for the wildebeest. This stage is marked by intense drama and incredible wildlife interactions.
-
August to October: Northern Serengeti and Mara River Crossing
- The herds reach the northern Serengeti and begin crossing the Mara River into the Maasai Mara in Kenya. This is one of the most famous and perilous parts of the migration.
- The river crossing is a spectacle of life and death as thousands of wildebeest plunge into the crocodile-filled waters. Despite the dangers, this crossing is crucial for accessing the abundant grazing lands of the Maasai Mara.
-
November: Return to the Serengeti
- As the short rains return to Tanzania, the herds begin their journey southward back into the Serengeti.
- The cycle starts anew as the animals prepare for the next calving season.
Dangers Along the Way
The Great Migration is not only a story of movement but also a tale of survival. The herds face numerous challenges on their journey:
- Predators: Lions, cheetahs, leopards, and hyenas closely follow the herds, preying on the weak, the young, and the injured.
- Crocodile-Infested Rivers: The Grumeti and Mara rivers are major obstacles, with crocodiles waiting to ambush the crossing herds.
- Exhaustion and Hunger: Long distances and changing environmental conditions test the animals’ endurance.
- Stampedes: With so many animals moving together, stampedes can occur during moments of panic, especially near rivers or predator attacks.
Despite these dangers, the migration is essential to the ecosystem. It ensures that grasses regenerate, nutrients are distributed across the plains, and predators have consistent food sources, maintaining balance in the savannah.
Where and When to Witness the Great Migration
To witness the Great Migration is to see nature at its most raw and spectacular. Choosing the right location and time of year is essential for catching key moments, from calving season to the dramatic river crossings.

Key Locations to View the Migration
-
Serengeti National Park, Tanzania
- Best for: Calving season and the early stages of the migration.
- The southern Serengeti is ideal from December to March, where the herds spread across the grassy plains of Ndutu. This is also when predators are most active due to the abundance of vulnerable newborn calves.
- As the herds move north in April and May, the central Serengeti offers excellent viewing opportunities with its expansive plains.
-
Grumeti River, Western Serengeti
- Best for: River crossings and predator activity in June and July.
- Witness the herds gathering at the Grumeti River, where massive crocodiles await their annual feast. Many safari lodges offer prime vantage points for observing this spectacle.
-
Mara River, Northern Serengeti and Maasai Mara
- Best for: The famous river crossings from July to October.
- This is one of the most dramatic stages of the migration as thousands of animals brave the turbulent waters. The northern Serengeti and the Maasai Mara in Kenya are both excellent for viewing these crossings.
-
Maasai Mara National Reserve, Kenya
- Best for: Grazing herds and predator interactions from August to October.
- The lush grasses of the Maasai Mara provide sustenance for the herds, and this period is marked by spectacular predator-prey dynamics.
Timing the Migration
The migration is a year-round phenomenon, but specific highlights occur at different times:
- December-March: Calving season in the southern Serengeti.
- June-July: River crossings at the Grumeti River.
- July-October: Mara River crossings and Maasai Mara grazing.
- November: The return journey southward to the Serengeti.
