The Great Migration is one of nature’s most breathtaking spectacles, often referred to as the “Greatest Show on Earth.” Each year, over 1.5 million wildebeest, accompanied by hundreds of thousands of zebras and gazelles, embark on an epic journey across the vast plains of the Serengeti (Tanzania) and the Maasai Mara (Kenya) in search of fresh grazing lands and water. This continuous cycle of movement is driven by seasonal rainfall, creating a dramatic wildlife display filled with survival, determination, and predator-prey interactions.

The Migration Route: Key Locations & Timing
December – March (Calving Season in the Southern Serengeti): This is the most critical period for wildebeest as they give birth to nearly 500,000 calves within a few weeks in the nutrient-rich Ndutu plains of the Southern Serengeti and Ngorongoro Conservation Area. Predators such as lions, cheetahs, and hyenas are highly active, taking advantage of the abundance of vulnerable young prey.

April – May (Movement Towards the Central Serengeti): As the rains subside, the herds begin their journey northward toward the Central Serengeti, particularly the Seronera Valley. The lush grasslands provide ample grazing opportunities, but the migration gains momentum as they prepare for the long trek ahead.

June – July (Grumeti River Crossing & Entry into the Northern Serengeti): This marks one of the migration’s most perilous stages. The herds cross the crocodile-infested Grumeti River, where hungry Nile crocodiles await their arrival. The survivors continue towards the Northern Serengeti, gradually approaching the Kenya-Tanzania border.

August – October (Dramatic Mara River Crossings in the Maasai Mara): The most iconic moment of the Great Migration happens at the Mara River. Thousands of wildebeest leap into the river, battling powerful currents and lurking predators to reach the Maasai Mara’s fertile grasslands. This is a spectacular time for wildlife viewing as the Mara plains fill with grazing herds and stalking predators.

November (Return to the Serengeti): As the short rains begin, the herds gradually move south, returning to the Serengeti in preparation for the next calving season, completing the cycle.

Best Time to Witness the Great Migration
June – October: Ideal for witnessing the dramatic river crossings at the Grumeti and Mara Rivers.
December – March: Perfect for experiencing the calving season, where large predator activity is at its peak.
April – May: While it’s the rainy season, this is a quieter time with lush landscapes and fewer tourists, offering a more intimate safari experience.
