The Wildebeest Migration, often called the Great Migration, is the largest land-based wildlife movement on Earth. Each year, over 1.5 million wildebeest, along with hundreds of thousands of zebras and gazelles, move in a continuous cycle through Tanzania’s Serengeti National Park and into Kenya in search of fresh grass and water.

This migration is driven by seasonal rainfall and is a year-round natural phenomenon, not a single event. Along the way, the herds face dramatic river crossings, predator encounters, and the birth of thousands of calves—making it one of the most spectacular safari experiences in Africa.

The Wildebeest Migration in Tanzania happens throughout the entire year, with different highlights depending on the season and location within the Serengeti National Park:

• January – March (Calving Season):
  The herds gather in the southern Serengeti and Ndutu region, where over 500,000 calves are born in just a few weeks. This is one of the best times to see predator action, as lions, cheetahs, and hyenas are highly active.
• April – June (Green Season Movement):
  The herds begin moving north and west through the central and western Serengeti as the rains end.
• July – October (River Crossings):
  The migration reaches the northern Serengeti, where dramatic crossings of the Mara River occur as animals move between Tanzania and Kenya.
• November – December (Return South):
  The herds begin their journey back toward the southern Serengeti as the rains return, completing the cycle.

Key takeaway:
The migration is always happening somewhere in Tanzania, timing your visit depends on which experience you want (calving, river crossings, or large moving herds).

The Wildebeest Migration takes place across different regions of the Serengeti National Park, and the best location depends on the time of year:

• Southern Serengeti & Ndutu (Dec–March):
  Best for calving season and predator activity
• Central Serengeti (April–June & Nov–Dec):
  Great for large herds on the move and excellent year-round game viewing
• Western Serengeti (May–June):
  Known for Grumeti River crossings and fewer crowds
• Northern Serengeti (July–October):
  Best for dramatic Mara River crossings

Pro tip:
A well-planned Tanzania safari often includes multiple Serengeti regions to follow the migration and maximize wildlife sightings.
