Serengeti Wildebeest Migration Safari

The Serengeti Wildebeest Migration is one of the world’s most incredible wildlife events, and it’s a highlight for many safari travelers. Each year, over 1.5 million wildebeest, joined by zebras and gazelles, make a 1,200-mile circular journey between Tanzania’s Serengeti National Park and Kenya’s Masai Mara. This guide provides a month-by-month breakdown, explains the reasons behind the migration, and explores the impact on the ecosystem, helping you to plan the perfect Serengeti Wildebeest Migration Safari.

Migration Routes

The Calving Season (December - February)

Wildebeest gather in the southern Serengeti and Ndutu Plains for calving. This area is part of the Ngorongoro Conservation Area, where rich grasslands support the birth of hundreds of thousands of wildebeest calves. Predator sightings peak here as lions, cheetahs, and hyenas move in for easy prey.

The Move to Western Serengeti (April - Early June)

The herds begin moving northwards, entering the Western Corridor and Grumeti Reserve, where they cross rivers that are home to large crocodiles. This period involves dangerous river crossings, a key highlight of the migration.

Mara River Crossings (July - September)

One of the most famous parts of the migration, the herds cross the Mara River into the Masai Mara in Kenya. Witnessing this high-drama spectacle is unforgettable as the animals face predators, deep waters, and intense currents.

Return South (October - November)

The herds begin their journey back south as the rains return to the Serengeti, arriving once again in the Ndutu Plains to repeat the cycle.

Best Time to Visit the Serengeti for the Migration

  • – December – February: Perfect for calving season in the southern Serengeti, with clear predator-prey interactions.
  • – April – Early June: Ideal for seeing the Grumeti River crossings in the western corridor, with high drama.
  • – July – September: Best for Mara River crossings in the northern Serengeti and Kenya’s Masai Mara.

The migration is active year-round, but timing your visit according to these highlights ensures you witness different stages and behaviors during this journey.

Reasons for the Migration

The wildebeest migration is a journey driven by the search for fresh water and grazing land. Dependent on seasonal rains to keep their food sources, these animals follow the rain across Tanzania and Kenya. This movement also provides a safe space for birthing and raising their young, helping them survive despite predators and seasonal changes.

Impact of the Migration on the Ecosystem

The Serengeti Wildebeest Migration plays a crucial role in maintaining the balance within the Serengeti ecosystem. Here’s how:

  • Vegetation Management: The grazing patterns of wildebeest help maintain the grasslands. By consuming large quantities of grass, they prevent overgrowth, which could lead to bush encroachment and reduce the availability of fresh grass.

  • Food Source for Predators: Predators like lions, cheetahs, hyenas, and crocodiles rely on the migration as a primary food source. The calving season, in particular, sustains many predator populations by providing an abundance of vulnerable prey.

  • Soil Fertility: As the wildebeest move, they leave behind nutrient-rich waste, fertilizing the soil and supporting vegetation growth, which benefits other herbivores and the overall biodiversity.

  • Ecosystem Connectivity: The migration serves as a natural regulator for species populations, maintaining balance across predator-prey dynamics and helping to sustain a diverse range of wildlife within the Serengeti and Maasai Mara ecosystems.

Best Time to Experience the Serengeti Wildebeest Migration
January – March: Calving Season

The southern Serengeti plains are lush from the short rains, making it the perfect place for wildebeest to give birth. This is an ideal time to witness the newborn calves and the predator activity they attract.

June – July: Grumeti River Crossings

The migration reaches the Grumeti River, where crocodiles await their chance to prey on crossing wildebeest. This is an exhilarating time for visitors, as it offers one of the most dramatic scenes of the migration.

August – September: Mara River Crossings

The wildebeest reach the Mara River in the northern Serengeti. This phase is a peak season due to the high drama of the river crossings, where thousands of animals brave the water and crocodiles to continue their journey.

October: Maasai Mara Rest

The wildebeest spread across the Maasai Mara in Kenya. This is a quieter period, though herds can still be seen grazing before they start heading south.

November – December: The Journey South

The onset of the short rains signals the wildebeest to move back south into the Serengeti, restarting the cycle.
