The Great Wildebeest Migration is one of the most remarkable wildlife spectacles on the planet. Each year, more than 1.5 million wildebeest, along with hundreds of thousands of zebras and gazelles, move across the vast plains of Serengeti National Park in Tanzania and into the Masai Mara National Reserve in Kenya.

This incredible journey follows the seasonal rains as the animals search for fresh grazing and water. Along the way, the herds face numerous challenges, including predators, dangerous river crossings, and long distances across the savannah.

For travelers planning a safari, understanding the migration’s movement throughout the year is essential. This month-by-month guide will help you know where the herds are likely to be and what kind of wildlife experiences you can expect.

January – March: Calving Season in Southern Serengeti

At the beginning of the year, the migration gathers in the southern plains of the Serengeti, particularly in the Ndutu area near the Ngorongoro Conservation Area.

This period is known as the calving season, when thousands of wildebeest calves are born every day. Within just a few weeks, hundreds of thousands of newborn animals appear on the plains.

The abundance of young animals attracts predators such as lions, cheetahs, and hyenas. As a result, visitors often witness dramatic predator-prey interactions. For wildlife photographers and safari enthusiasts, this is one of the most exciting times to visit the Serengeti.

The southern plains are also incredibly scenic during this time, with wide open grasslands stretching as far as the eye can see.

April – May: Migration Through Central Serengeti

As the rainy season continues, the enormous herds begin moving north toward the central Serengeti.

The landscape during this time is lush and green, providing plenty of grazing for the animals. Large columns of wildebeest stretch across the plains, creating spectacular wildlife scenes.

Although occasional rains may occur, April and May offer quieter parks and fewer visitors. This means travelers can enjoy excellent wildlife viewing without large crowds.

Many predators follow the migration closely, ensuring exciting game drives throughout the central Serengeti.

June – July: Western Corridor and Grumeti River Crossings

By early summer, the migration reaches the western corridor of the Serengeti near the Grumeti River.

This is where the herds encounter one of their first major obstacles: crossing crocodile-infested rivers. The Grumeti River crossings may not be as famous as the Mara River crossings, but they still provide thrilling wildlife encounters.

Massive Nile crocodiles wait patiently in the water as thousands of animals attempt to cross. The tension and unpredictability of these crossings make them unforgettable moments for visitors.

At this time of year, the Serengeti landscape begins to dry out, encouraging the herds to continue their journey north.

August – October: Mara River Crossings

Perhaps the most famous stage of the migration occurs when the herds reach the northern Serengeti near the Mara River.

This is when thousands of wildebeest gather at steep riverbanks before suddenly plunging into the water. The crossings are dramatic and unpredictable, with animals scrambling up the opposite bank while avoiding powerful river currents and crocodiles.

These scenes have become iconic images of the African safari experience.

Many animals cross into the nearby Masai Mara National Reserve, where they continue grazing before eventually returning to Tanzania later in the year.

Because of the dramatic river crossings, this period is one of the most popular times to visit the Serengeti.

November – December: Return to the Southern Plains

As the short rains begin in November, the migration slowly moves south again toward the fertile plains of the Serengeti.

Fresh grass grows quickly after the rains, attracting the herds back to the southern regions.

During this time, the animals spread out across the central and southern Serengeti, feeding and preparing for the next calving season that will begin in January.

This completes the annual cycle of the Great Migration before the journey starts again.

Best Time to See the Serengeti Great Migration

The migration can be seen throughout the year, but different seasons offer different highlights.

• January – March: Calving season and intense predator activity

No matter when you visit, the Serengeti offers incredible wildlife viewing opportunities.

Why the Great Migration Is One of Africa’s Greatest Wildlife Events
