The Story of the Wildebeest Migration: Safari Science, Challenges, and Facts

The migration follows a continuous, clockwise loop through Tanzania and Kenya, covering about 1,800 miles (2,900 km). Here’s how it unfolds:

January – March: Calving Season (Southern Serengeti / Ndutu Area)

• The herds gather in the Ndutu region, where fresh grasses cover the volcanic plains.
• Around 8,000 wildebeest calves are born daily during peak season.
• It’s a paradise for predators — lions, cheetahs, and hyenas are highly active.

Best for: Births, predator action, and photography.

April – May: Rainy Season Movement (Central Serengeti)

• As rains return, the herds begin moving northwest in search of greener pastures.
• The herds spread out across the central Serengeti, creating dramatic river crossings.

Best for: Lush scenery, fewer crowds, and dramatic landscapes.

June – July: Grumeti River Crossing (Western Corridor)

• Wildebeest face their first major challenge: the crocodile-infested Grumeti River.
• Smaller than the Mara River crossings, but equally dramatic.

Best for: Action-packed viewing and predator-prey tension.

August – October: Mara River Crossings (Northern Serengeti)

• The most iconic part of the migration — wildebeest crossing the Mara River into Kenya.
• Thousands plunge into the water, many falling victim to crocodiles or strong currents.

Best for: Peak migration scenes, drama, and incredible photography.

November – December: Return to the South

• After short rains, the herds start heading south toward the Serengeti again.
• Grass regrowth in Ndutu signals the beginning of the next calving season.
