The Great Wildebeest Migration is not a single event; it is a continuous, year-long pilgrimage driven by the rains. Over 1.5 million wildebeest, accompanied by hundreds of thousands of zebra and gazelle, journey in a clockwise loop through the vast plains of the Serengeti in Tanzania and the Masai Mara in Kenya.
The most common question we are asked is, “When should I go to see it?” The answer depends entirely on what you want to see. As journalists who have filmed this spectacle for years, we have learned that each chapter of this story offers its own unique drama.
This is our definitive, month-by-month guide to help you be in the right place at the right time.
Key Takeaways (The 20-Second Guide)
- For River Crossings: The most famous and dramatic events. Plan for July to September in the Northern Serengeti (Tanzania) or Masai Mara (Kenya).
- For Newborn Calves: To see the calving season and intense predator action, plan for January to March in the Southern Serengeti (Ndutu region).
- For Huge Herds on the Plains: To witness the massive herds gathering before they move north, plan for April to June in the Central and Western Serengeti.
January – March: The Calving Season in the Southern Serengeti
This is a period of incredible life and drama. The vast, short-grass plains of the Southern Serengeti and the Ndutu Conservation Area are where the herds congregate to give birth.
- What You Will See: An estimated 500,000 wildebeest calves are born in a three-week window, typically in February. The landscape is covered in newborn animals, which creates a magnet for predators. This is one of the best times to witness lion, cheetah, and hyena hunts.
- Our Perspective: For photographers and those seeking a story of rebirth and survival, this is our favorite time. The landscape is lush and green from the short rains. During our visit last February, the sheer density of life was staggering.
April – May: The Journey North Begins
This is a transitional period as the long rains begin. The herds begin to move north and west from the southern plains in search of fresh grazing.
- What You Will See: The massive herds begin to form long, dramatic columns as they move across the plains of the Central and Western Serengeti. The scenery is vibrant, with dramatic storm clouds creating beautiful skies.
- Our Perspective: This is the “shoulder season.” You will experience fewer crowds and often better value. While rain is possible, it typically comes in short, powerful afternoon thunderstorms. It requires some flexibility but can be incredibly rewarding.
June – July: The Western Corridor and the Grumeti River
The migration continues its push north. The herds consolidate in the Serengeti’s Western Corridor, where they face their first major obstacle: the Grumeti River.
- What You Will See: The Grumeti is home to enormous crocodiles, and while the crossings here are not as famous as the Mara River, they can be just as dramatic. This is a period of high drama as the herds build up before attempting to cross.
- Our Perspective: This is an excellent time to visit, offering a great balance of spectacular herd movements and fewer visitors than the peak season further north.
August – October: The Mara River Crossings (Peak Season)
This is the most famous chapter of the migration. The herds have reached the northernmost part of the Serengeti and the Masai Mara in Kenya, where they must cross the treacherous Mara River.
- What You Will See: This is the spectacle you have seen in documentaries. Huge herds build up on the banks of the river, hesitating for hours or even days before making the chaotic, life-or-death plunge into crocodile-infested waters.
- Our Perspective: Witnessing a Mara River crossing is one of the most unforgettable experiences in the natural world. It requires patience. We often spend a full day waiting for the right moment. This is peak season, so booking up to a year in advance is essential.
November – December: The Return South
After the short rains begin in November, the herds start their journey south again. They move from the Masai Mara and Northern Serengeti back down through the eastern and central plains.
- What You Will See: The herds are more dispersed but are constantly on the move, drawn by the promise of fresh grass in the south. This is a time of plenty for the resident predators.
- Our Perspective: This is another excellent shoulder season. The crowds of peak season have departed, and the landscape begins to turn green again. It is a beautiful time to be in the Serengeti.
Ultimately, the Great Migration is a fluid, natural event. Our job is to use our deep, first-hand knowledge to move beyond a simple map and place you in the heart of the action, no matter which chapter of the story you choose to witness.
