Serengeti Wildebeest Migration Guide: Month by Month, Calving and River Crossings
The Serengeti wildebeest migration is the year-round movement of more than 1.5 million wildebeest, with hundreds of thousands of zebra and gazelles, through the Serengeti and Kenya's Masai Mara in search of fresh grass and water. The herds calve in the southern Serengeti from December to March, peaking in February, cross the Grumeti River from June to July and cross the Mara River from July to October. Exact timing follows the rains, so choose your camp location to match your travel month.
The Serengeti wildebeest migration, often called the Great Migration, is the largest overland movement of animals on Earth and one of the greatest wildlife spectacles in Africa. Seeing it at its best depends on being in the right place at the right time, because the herds are always moving across a vast ecosystem. This expert guide explains what the migration is, where the herds are each month, calving versus river crossings, where to stay, how long you need, costs, photography and packing, and how to plan a private, tailor-made Great Migration safari with our experienced Tanzania team in Arusha.
What Is the Serengeti Wildebeest Migration?
The Serengeti wildebeest migration is a continuous, year-round journey of vast herds following the rains in a broad, roughly circular route through the Serengeti-Mara ecosystem. It is not a single event on one date, but a constantly changing cycle of grazing, calving, rutting and river crossings that moves with the seasons. The table below summarises the key facts about the Great Migration, helping you understand the animals involved, the route they follow and why they move. Knowing these basics makes it much easier to choose the best month and the right Serengeti region for your private safari in Tanzania.
| Fact | Details |
|---|---|
| Animals | More than 1.5 million wildebeest with hundreds of thousands of zebra and gazelles |
| Ecosystem | Serengeti National Park in Tanzania and the Masai Mara in Kenya |
| Why they move | To follow rainfall, fresh grazing and water |
| Route | A broad clockwise circuit through the south, west and north |
| Time in Tanzania | The herds spend most of the year in the Serengeti |
| Predators | Lions, cheetahs, leopards, hyenas and crocodiles follow the herds |
Great Migration Month by Month
The location of the herds changes throughout the year, so understanding the migration calendar is the key to planning a successful Great Migration safari in Tanzania. Each stage offers a different experience, from newborn calves and predator action in the south to dramatic river crossings in the far north of the Serengeti. The five tabs below follow the wildebeest migration month by month, showing where the herds usually are, the main wildlife highlights and the typical weather. Timing shifts with the rains each year, so we track herd movements very closely and plan your camps and game drives accordingly.
Calving Season in the Southern Serengeti
Southern Serengeti and Ndutu
Wildebeest calving
From December to March, the herds graze the nutrient-rich short-grass plains of the southern Serengeti and the Ndutu area. Calving usually peaks in February, when hundreds of thousands of calves are born over just a few weeks. The abundance of young animals attracts lions, cheetahs and hyenas, creating some of the most exciting predator action of the year.
Ndutu calving season safari →Long Rains and the Move North
Southern and central Serengeti
Huge columns on the move
As the long rains arrive in April and May, the herds begin to gather and move north and west through the central Serengeti. Long columns of wildebeest and zebra stretch across green plains, and the rutting season begins as males compete noisily for females. Parks are quiet, landscapes are lush and many lodges offer attractive green-season rates.
Serengeti National Park →Western Corridor and Grumeti River
Western Corridor and central Serengeti
Grumeti River crossings
By June, many herds reach the Western Corridor, where they must cross the Grumeti River and its waiting Nile crocodiles. These crossings are smaller than those on the Mara River but no less dramatic, with far fewer vehicles around. The dry season begins, grass shortens and wildlife viewing becomes easier as animals gather near water sources.
Western Corridor migration safari →Mara River Crossings in the Northern Serengeti
Northern Serengeti and Kogatende
Mara River crossings
From July to October, the herds reach the northern Serengeti and move back and forth across the Mara River between Tanzania and Kenya. Thousands of wildebeest may plunge into the river at once, braving steep banks, strong currents and crocodiles. This is the most famous stage of the Great Migration and the most popular time to travel.
Great Migration river crossing →The Return South with the Short Rains
Eastern and central Serengeti
Herds return south
When the short rains begin in November, the herds leave the north and travel south through the eastern Serengeti and the Lobo area. Fresh grass appears quickly, and the plains around Seronera and the south start to fill again with wildebeest and zebra. It is a quiet, beautiful time of year with good value and dramatic skies.
Great Migration safari packages →Calving Season vs River Crossings
Most travellers planning a Great Migration safari choose between the calving season in the southern Serengeti and the river crossings in the north of the park. Both are truly extraordinary experiences, but they differ in timing, landscapes, wildlife behaviour and the number of other vehicles you are likely to see. The table below compares calving season and river crossings side by side, helping you decide which stage of the wildebeest migration best matches your interests. Many keen wildlife lovers return to Tanzania to experience both, as each one offers a completely different and unforgettable perspective on the Serengeti.
| Calving season | River crossings | |
|---|---|---|
| Months | December to March, peak in February | July to October |
| Region | Southern Serengeti and Ndutu | Northern Serengeti and Kogatende |
| Main highlight | Newborn calves and predator action | Herds crossing the Mara River |
| Landscape | Green, open short-grass plains | Rolling hills and riverbanks |
| Weather | Warm with short showers | Dry and sunny |
| Best for | Photographers and predator lovers | Dramatic action and classic migration scenes |
Where to Stay During the Migration
Choosing the right camp location is the most important decision on a Great Migration safari, because the Serengeti is enormous and driving distances are long. Staying close to the herds means more time watching wildlife and less time on the road, especially during the short and unpredictable river crossing season. The table below shows the best Serengeti areas to stay in for each stage of the migration, along with the type of accommodation that works best there. Seasonal mobile camps move with the herds several times a year, offering an authentic and well-positioned migration experience throughout the year.
| Months | Where to stay | Accommodation style |
|---|---|---|
| December to March | Southern Serengeti and Ndutu | Mobile camps and Ndutu lodges |
| April to May | Central Serengeti and Seronera | Lodges and tented camps with green-season rates |
| June to July | Western Corridor and Grumeti | Tented camps and lodges near the river |
| July to October | Northern Serengeti and Kogatende | Mobile and permanent camps near the Mara River |
| November | Central and eastern Serengeti | Lodges and tented camps around Seronera and Lobo |
How Long Should a Migration Safari Be?
A Great Migration safari needs enough time to allow for unpredictable herd movements, because wildlife does not follow a timetable and crossings can happen at any moment. Spending a few more nights in the right region greatly increases your chance of seeing calving, predator action or a dramatic river crossing on your safari. The table below suggests how long to spend on a migration safari and what each trip length allows you to experience in the Serengeti and beyond. Many travellers combine the migration with the Ngorongoro Crater and Tarangire for a complete and rewarding Northern Tanzania wildlife safari.
| Trip length | What it allows |
|---|---|
| 3 nights in the Serengeti | A good introduction to one migration region |
| 4 to 5 nights in the Serengeti | More time to wait for crossings or predator action |
| 6 nights or more | Two regions or a dedicated photography safari |
| 7 to 10 days in Tanzania | Migration with Ngorongoro, Tarangire and Lake Manyara |
How Much Does a Migration Safari Cost?
The cost of a Great Migration safari depends on your accommodation level, the season, the number of nights and whether you travel by road or fly into the Serengeti. Peak months for river crossings usually cost the most, while the green season in April and May offers excellent value with quiet parks and lush landscapes.
