The Great Wildebeest Migration: When, Where and How to See It in Kenya and Tanzania

The Greatest Wildlife Spectacle on Earth

Every year, over 1.5 million wildebeest — along with hundreds of thousands of zebras, gazelles, and eland — undertake a circular journey of roughly 3,000 kilometres between Tanzania’s Serengeti and Kenya’s Masai Mara. It’s the largest overland animal migration on the planet, and it’s been happening for thousands of years, driven by rainfall and the search for fresh grazing.

This is not a single event but a continuous cycle. The herds are always moving, always following the rains, always being pursued by predators. To witness it is to see the raw engine of the African ecosystem at work — life, death, and survival playing out on an unimaginable scale.

The Migration Calendar: Month by Month

Understanding the migration cycle is key to planning your trip. In January and February, the herds are in the southern Serengeti and Ndutu area, where over 500,000 calves are born in a few short weeks — attracting predators from across the ecosystem. From March to May, the herds begin moving northwest through the central Serengeti, following the rains toward fresh pastures.

June and July see the herds reaching the western Serengeti and the Grumeti River, where the first dramatic river crossings occur. From August to October, the migration reaches the Masai Mara in Kenya, and the famous Mara River crossings take centre stage — perhaps the single most dramatic wildlife event you can witness anywhere. November and December see the herds beginning their journey south again, back toward the Serengeti calving grounds.

The Mara River Crossings

The Mara River crossings are what most people picture when they think of the Great Migration. Thousands of wildebeest gather on the riverbanks, building courage to plunge into the crocodile-infested waters. The crossings are chaotic, desperate, and awe-inspiring — animals scramble over each other, crocodiles launch ambush attacks, and the sound of hooves and splashing water fills the air. Not every animal makes it across, but those that do emerge on the other side to find the fresh, green grazing that drove them to take the risk.

Timing a river crossing requires patience. The herds can gather on the bank for hours — or even days — before making the plunge. Our guides know the best crossing points and will position you for the best possible viewing experience.

Beyond the Crossings

While the river crossings get the most attention, the migration is spectacular throughout the year. The calving season in the southern Serengeti (January-February) is an incredible experience, with thousands of baby wildebeest taking their first steps while predators circle. The long columns of wildebeest stretching across the plains during the main migration months are a sight that defies comprehension — a living river of animals as far as the eye can see.
