The Great Migration is one of the world's most extraordinary natural events and is often regarded as the greatest wildlife spectacle on Earth. Every year, over two million wildebeest, accompanied by hundreds of thousands of zebras and gazelles, journey across the vast plains of Tanzania's Serengeti National Park and Kenya's Maasai Mara National Reserve in search of fresh grazing and water.
This incredible movement is driven by seasonal rainfall and has remained one of Africa's most remarkable natural cycles for thousands of years. For wildlife enthusiasts, photographers, and adventure seekers, witnessing the Great Migration is an unforgettable safari experience.

What is the Great Migration?

The Great Migration is a continuous, circular movement of wildlife between the Serengeti ecosystem in Tanzania and the Maasai Mara ecosystem in Kenya. Contrary to popular belief, it is not a single event but a year-round journey influenced by rainfall patterns and the availability of food.

The migration primarily involves:

• More than 1.5 million wildebeest

• Around 300,000 zebras

• Hundreds of thousands of Thomson's and Grant's gazelles

• Other herbivores that travel alongside the herds

As the animals migrate, they are followed by predators such as lions, leopards, cheetahs, hyenas, crocodiles, and wild dogs, creating one of the most dramatic wildlife spectacles in the world.

Why Does the Great Migration Happen?

The migration is driven by one simple factor: survival.

As rainfall shifts across East Africa, fresh grass begins to grow in different areas. Wildebeest and other grazing animals instinctively move toward these nutrient-rich grazing grounds, ensuring they have enough food and water throughout the year.

This constant search for resources creates an endless cycle of movement that has shaped the Serengeti-Maasai Mara ecosystem for centuries.

The Great Migration Calendar

Although weather patterns can vary slightly each year, the migration generally follows this cycle.

January to March – Calving Season

During the early months of the year, the herds gather in the southern Serengeti and the Ndutu Conservation Area.

This is the calving season, when more than 500,000 wildebeest calves are born within a few weeks.

The abundance of newborn animals attracts predators, making this one of the best times to witness dramatic wildlife interactions.

Highlights

• Thousands of newborn calves

• High predator activity

• Excellent wildlife photography

April to May – The Long Rains

As the rains begin, the herds gradually move northwest through the central and western Serengeti.

The landscape becomes lush and green, while safari crowds remain relatively low.

Highlights

• Beautiful scenery

• Fewer tourists

• Excellent birdwatching

June to July – Grumeti River Crossings

By mid-year, the herds reach the western Serengeti and prepare to cross the Grumeti River.

Here, crocodiles lie in wait, creating dramatic moments as thousands of animals brave the river in search of greener pastures.

Highlights

• River crossings

• Crocodile encounters

• Spectacular photography opportunities

July to October – Mara River Crossings

This is the most famous stage of the migration.

The herds move into Kenya's Maasai Mara, crossing the dangerous Mara River, where strong currents and massive Nile crocodiles present one of the greatest challenges of the journey.

These river crossings are among the most sought-after wildlife experiences in Africa.

Highlights

• Famous Mara River crossings

• Big Five safaris

• Exceptional predator sightings

November to December – Return to Tanzania

As the short rains begin in Tanzania, the herds leave the Maasai Mara and gradually return to the Serengeti.

This marks the beginning of another migration cycle.

Highlights

• Returning herds

• Green landscapes

• Excellent game viewing
