Private journeys timed around calving season, the moving herds and the river-crossing months. More on the other animals you will meet in our safari animals guide.
The Great Migration in Africa is the continuous, year-round movement of wildebeest, zebras and gazelles through the Serengeti–Mara ecosystem, shaped by rainfall, fresh grazing and the instinct to survive. It is not a single event or one dramatic river crossing. Estimates range from about 1.2 to 1.5 million wildebeest, traveling with hundreds of thousands of zebras and gazelles, some two million animals in all. Often called the greatest show on Earth, it is an iconic wildlife spectacle and a natural phenomenon few places can match.
In short: about 1.2 to 1.5 million wildebeest, with hundreds of thousands of zebras and gazelles, circle the Serengeti–Mara ecosystem every year. They calve in the southern Serengeti from about January to March and cross the Mara River in the northern Serengeti and Kenya’s Maasai Mara from about July to October.
For travelers researching a Great Migration Africa safari, the most important decision is not simply when to travel. It is choosing the right region for the season, allowing enough time, and understanding that the herds follow nature rather than a fixed calendar.
This guide explains how the migration works, where the herds are usually found throughout the year, and how to plan a beautifully paced safari without relying on promises that no responsible safari specialist can make.
What Is the Great Wildebeest Migration?
The Great Wildebeest Migration is the annual movement of vast herds between Tanzania’s Serengeti National Park and Kenya’s Maasai Mara National Reserve, often spelled Masai Mara. Wildebeest form the largest part of the migration, accompanied by zebra, Thomson’s and Grant’s gazelles, eland and other grazing animals.
The journey is often shown as a neat clockwise circle, but the reality is far more complex. Herds may move forward, double back, spread across a wide area, divide into smaller groups or remain in one place while grazing and water are plentiful. Some animals take different routes through the central, western or eastern Serengeti before joining larger concentrations again.
An individual wildebeest may travel approximately 800 to 1,000 kilometers (about 500 to 620 miles) during the cycle. Along the way, the herds give birth, graze, mate and cross rivers while lions, cheetahs, leopards, hyenas and crocodiles follow the abundance of prey.
It is this constant relationship between weather, landscape, herbivores and predators that makes the migration much more than a seasonal wildlife event. It is the Serengeti–Mara ecosystem in motion.
Why Do the Wildebeest Migrate?
In short, the herds move in search of greener pastures. The migration is driven principally by rain, water and the growth of new grass, so rainfall patterns decide where the migratory herds go next. When rain falls, fresh grass and grazing follow. As one area dries or is depleted, the herds begin searching for the next productive landscape.
The short-grass plains of the southern Serengeti are especially important. Their mineral-rich volcanic soils produce nutritious grass that supports pregnant wildebeest and nursing mothers during the calving season. As the long rains end and these southern plains begin to dry, many herds move toward the central Serengeti and Western Corridor before continuing north.
Zebra and wildebeest also use the grasslands differently. Zebra can feed on taller, coarser grass, while wildebeest favor the shorter new growth that follows. Smaller grazers then feed closer to the ground. Together, they make remarkably efficient use of the plains.
The broad pattern is predictable; the detail is not. Rainfall has become increasingly variable, so traditional migration dates should always be treated as informed guidance rather than a timetable.

Predators of the Great Migration
Where the herds go, the predators follow. Lion prides and spotted hyena clans follow the wildebeest across the Serengeti plains, cheetah, which hunt Thomson’s gazelle as well as young wildebeest, thrive on the open short-grass country of the southern Serengeti during calving season, and leopard keep to the riverine woodland and rocky kopjes. At the Grumeti and Mara rivers, large Nile crocodiles wait at the crossing points.
The same areas hold elephant, buffalo, giraffe, topi and rich birdlife, including vultures, storks and other birds that follow the herds, so a migration safari is a complete wildlife safari, not only a wildebeest one. If seeing the Big Five matters to you, our Big Five safari guide explains where to look.

Planning Your Safari Around the Migration Seasons
There is wildlife throughout the Serengeti and Maasai Mara in every season. The following guide describes the herds’ usual pattern, but actual locations can change from week to week.
Season 01
January to March: Calving in the Southern Serengeti
From January through March, the main herds are generally found across the southern Serengeti and adjoining short-grass plains of the Ngorongoro Conservation Area, including Ndutu. The migration extends into the conservation area, but not into Ngorongoro Crater.
Most calves are born in February, when calving usually reaches its height, although births occur throughout the wider January-to-March period. Up to half a million wildebeest calves, roughly 500,000, may be born within a few weeks across the short-grass plains from Naabi Hill to Ndutu and Kusini. Newborn wildebeest can stand within minutes, an essential ability in a landscape where the herd may move and predators are always nearby.
This is one of the most rewarding seasons for travelers interested in newborn wildlife, predator interaction and photography. Lions, cheetahs and hyenas are active around the herds, while the plains are often green and expansive after the rains.
Calving season can also feel more intimate than the famous river-crossing months. It is an excellent choice for travelers who value wildlife depth and atmosphere more than one headline moment. Our guide to wildebeest calving season in Ndutu covers those weeks in detail.
Calving season · the southern Serengeti
Season 02
April to May: Central Serengeti and the Western Movement
As the southern grasslands begin to dry, the migration starts moving north and west. The precise departure can occur from late April into early June, depending on rainfall.
During this period, the herds are often fragmented rather than traveling as one enormous group. This is also the mating season, or rut. Long columns of wildebeest may pass through the central Serengeti toward the Western Corridor, while other groups take routes past Seronera and the Moru Kopjes, through Lobo or along the eastern side of the ecosystem.
April and May can offer striking green scenery, fewer vehicles and excellent value. Full-day game drives with a thoughtfully prepared picnic allow guides the freedom to search widely for moving herds. The central Serengeti is also known for resident big cats, so the safari remains rewarding even when the migration is dispersed.
Travelers should be comfortable with the possibility of seasonal rain. In return, they may experience dramatic skies, vivid landscapes and a quieter Serengeti.
Season 03
June to July: The Western Corridor and Grumeti
By June, many splinter herds begin gathering in the Western Corridor. Here, the migration encounters the Grumeti River before continuing toward the northern Serengeti.
Crossing the Grumeti, the herds face large crocodiles, and the river also runs through the neighboring Grumeti Reserve. Grumeti crossings are different from the steep, crowded scenes often associated with the Mara River. The timing varies, and the herds can gather near the water before deciding whether to cross. Crocodiles are present, but a crossing should never be promised. For the Mara crossings themselves, see our guide to when and where the Mara River crossings happen.
The wider western Serengeti deserves attention beyond the river. Its woodlands, open plains and riverine habitats support lions, leopards, elephants and abundant resident game. This makes it possible to build a complete safari rather than waiting for a single moment at the water.
Late June and July also mark the gradual transition toward northern Serengeti migration season. Selecting a camp with the right seasonal location becomes increasingly important.
Season 04
August to October: Northern Serengeti and the Mara River
From approximately July or August through October, substantial herds are usually found across the northern Serengeti and Kenya’s Maasai Mara. This is the season most closely associated with dramatic Mara River crossings.
Herds of wildebeest congregate on the banks before crossing the Mara, and witnessing one of these dramatic river crossings is a highlight of many safaris. The river has numerous recognized crossing points rather than one dependable location. Wildebeest may gather along a bank for hours or days, cross suddenly, retreat at the last moment or move to another section of the river. They may also cross back and forth between Tanzania and Kenya as grazing and water conditions change.
In a drier year, some herds can reach the Mara River in early July. In a wetter year, major concentrations may arrive later, sometimes in August. Even at the height of the season, not every animal enters Kenya; significant numbers can remain in the northern Serengeti.
August and September are popular and camps often fill well in advance. For the best choice of accommodation and private guiding, planning 12 to 18 months ahead is sensible. October may provide a quieter atmosphere while still offering excellent northern wildlife and possible migration activity.

Season 05
November to December: The Return South
As the short rains begin, the herds gradually turn south. Their return is rarely a single, orderly procession. Some travel through the Lobo area and the eastern Serengeti, while others move through the central or western regions at different speeds.
By late November and December, parts of the migration may reach the central and southern Serengeti, drawn toward renewed short-grass grazing. If rain falls in an unexpected area, the herds can pause, change direction or return temporarily to where conditions are better.
This transitional period can offer impressive moving columns, fresh landscapes and fewer visitors than peak river-crossing season. It is particularly suited to flexible travelers who appreciate the wider safari experience and are willing to follow the guidance of expert local teams.
When Is the Best Time to See the Great Migration?
There is no single best month for everyone; our month-by-month calendar above shows where the herds usually are. The right time of year depends on the experience you value most.

If a river crossing is your priority, spending several nights in the northern migration region gives you a better opportunity than a rushed visit. It still does not create a guarantee. If your priority is newborn animals, predator action and luminous green plains, February and early March can be equally — if not more — compelling.
No. Mara River crossings are completely natural and cannot be scheduled or guaranteed.
A herd may approach the river and wait for days. It may cross before your vehicle reaches the area, move to a different crossing point or turn away altogether. Water levels, grazing, weather, pressure from other animals and perceived danger can all influence the decision.
A responsible Great Migration safari therefore focuses on creating the strongest possible conditions:
Stay in the correct region for the season.
Allow at least three or four nights in a key migration area.
Use an experienced guide with current local knowledge.
Consider a private vehicle for greater flexibility.
Avoid building the entire safari around one crossing.
The finest migration journeys leave room for nature to lead. A crossing can be extraordinary, but so can watching thousands of wildebeest move across open plains, seeing a cheetah scan a herd, or hearing wildebeest around camp after dark.
Avoiding the crowds at the crossings
In the dry season, from about July to October, the best-known crossing points can draw many vehicles, especially in August. A few choices make a real difference: travel in early July or late October, stay at a camp close to the river rather than a long drive away, and take a full-day game drive with a packed lunch so you can wait at the river when others leave.
Pairing the river with a few nights in one of Kenya’s private Mara conservancies, which limit vehicle numbers at sightings, also helps. Our guide to when and where the Mara River crossings happen explains the crossing points in detail.
Choosing Your Base in the Northern Serengeti
The best base depends on the specific camp’s location, your travel dates and access to likely viewing areas. Driving times can change with road conditions, available river crossings and herd movements.
Compare individual camps rather than choosing solely by area name. A split stay may suit some itineraries, but it is not essential for every migration safari. Allow enough time for wildlife viewing and consider whether changing camps adds value to your journey. Our guide to choosing between Kogatende and Lamai explains what to compare.
A hot-air balloon safari is one of the most memorable ways to see the herds on a Serengeti safari. Flights lift off at sunrise, drift for roughly an hour over the plains, and end with a champagne bush breakfast where the balloon lands.
In the Serengeti, the central Seronera area flies all year and operators move seasonal bases to follow the migration; flights also operate over the Maasai Mara. We match your flight to the area where the herds are most likely to be, and never book it for the morning you change camps. Our guide to hot-air balloon safari costs explains what the flight includes.

Tanzania or Kenya for the Great Migration?
Both countries offer exceptional migration experiences, but they provide different perspectives. For a fuller comparison, read our Kenya vs Tanzania safari guide.
The Great Migration in Tanzania
Tanzania hosts the migration through much of its annual cycle. The Serengeti offers the southern calving plains, central migration routes, Western Corridor, Grumeti River and northern Mara River region.
A Tanzania Great Migration safari provides the greatest seasonal variety and combines naturally with Ngorongoro Crater, Tarangire, Lake Manyara or a Zanzibar beach retreat. Travelers can also connect distant Serengeti regions by light aircraft, reducing long drives and creating a more elegant itinerary.
The Great Migration in Kenya
Kenya’s Maasai Mara is most strongly associated with the northern migration months, generally from July into October. The reserve and neighboring conservancies also support superb resident wildlife, particularly big cats.
Kenya can combine easily with Nairobi, Laikipia, Lewa or the Indian Ocean coast. For travelers seeking both the Serengeti and Maasai Mara, a carefully planned cross-border itinerary offers contrasting landscapes and safari styles — but it should include enough nights in each location to justify the additional travel.
The best choice is not automatically the country with the most famous photograph. It is the destination and camp position that best match your dates, interests and preferred pace.
Mobile Camps or Permanent Luxury Lodges?
Mobile migration camps relocate between designated seasonal sites. Other camps remain in one location but operate for only part of the year. Confirm each camp’s location and opening dates for your intended stay.
Mobile camps relocate between designated seasonal sites to remain close to likely herd movements. They offer an immersive tented experience and often provide excellent access to key migration areas. Their charm lies in intimacy, atmosphere and connection to the landscape rather than extensive resort-style facilities.
Permanent camps and lodges remain in one location throughout the year. They may offer larger suites, swimming pools, wellness facilities and a broader range of amenities. A well-positioned permanent property can also provide outstanding resident wildlife even when the main herds have moved elsewhere.
For many travelers, the ideal itinerary combines both: a strategically positioned migration camp for wildlife access and a permanent luxury lodge for space, privacy and time to slow down.

How Many Days Do You Need?
For a meaningful migration experience, plan at least three or four nights in the region where the herds are expected. Four nights provide three full safari days and improve flexibility when herd locations change.
A complete northern Tanzania safari generally works beautifully over seven to ten nights, depending on the number of regions included. A Tanzania and Kenya combination usually requires additional time so that international border logistics do not overpower the safari itself.
Private flying can make longer itineraries more comfortable, especially when combining the southern, western or northern Serengeti with other destinations. The aim should be fewer, better-chosen stops rather than changing camps every night or two.
Planning the Migration for Different Travelers
Couples and Honeymooners
Choose intimate camps, private dining, secluded suites and an itinerary with time to enjoy the property between game drives. A safari-and-beach combination can balance the excitement of the migration with a restorative coastal stay.
Families
Look for family accommodation, flexible meal times, guides who engage younger travelers and age-appropriate activities. Calving season can be fascinating for children, although families should understand that predator encounters may sometimes be graphic.
Photographers
A private vehicle provides greater control over positioning, departure times and time spent at a sighting. Consider vehicle configuration, charging facilities, luggage allowances on light aircraft and the direction of seasonal light when selecting a camp.
Travelers Seeking Privacy
Avoid assuming that peak season automatically produces the best safari. Calving season, the green months and October can offer extraordinary wildlife with a different rhythm. Carefully selected private concessions or quieter camp locations can further reduce vehicle density, although the busiest river-crossing points may still attract multiple vehicles.

Older Travelers
The migration suits travelers in their 60s, 70s and beyond. Fly into the Serengeti rather than driving, stay three or four nights in one well-placed camp, and choose the season for comfort as well as wildlife: the calving months bring green landscapes and fewer vehicles, while river-crossing season can mean long waits at the river on dusty days. Ngorongoro Crater sits at about 7,500 feet, so mention any heart or lung concerns when planning. Our guide to the best African safaris for seniors covers pacing, health and the easiest destinations.
How to Plan a Great Migration Safari
A well-designed migration safari begins with the traveler — not a standard route. Your dates, preferred level of privacy, wildlife priorities, comfort expectations and tolerance for changing camps should determine the itinerary.
At NndeeAfrika, we recommend focusing on five principles:
1
Match the region to the season. Camp location matters more than a famous name.
2
Stay long enough. Several nights provide flexibility and a more relaxed experience.
3
Keep expectations honest. The migration can be anticipated but never controlled.
4
Protect the quality of the whole journey. Resident wildlife, guiding, scenery, service and pacing matter even when the herds change direction.
5
Plan early for peak periods. The most desirable camps, family suites and private vehicles are limited.
This approach creates a safari that remains exceptional whether you witness a dramatic river crossing, a vast herd on the open plains or an unexpectedly quiet moment far from other vehicles.

Sample Great Migration safaris we plan privately. Each is a starting point, timed to your month and adjusted to your pace.
Following the Herds (11 days): camps positioned with the herds on both sides of the Mara River, timed to the month you travel.
Yes. The herds remain within the wider Serengeti–Mara ecosystem throughout the year. What changes is their probable location and behavior.
What months is the Great Migration in Africa?
+
The Great Migration happens all year. Roughly: January to March, calving in the southern Serengeti around Ndutu; April and May, the herds move through the central Serengeti; June and July, the Western Corridor and the Grumeti River; July or August to October, the northern Serengeti and Kenya’s Maasai Mara for the Mara River crossings; November and December, the herds return south through the eastern and central Serengeti.
What is the best month for the Great Migration in Tanzania?
+
February is excellent for calving in the southern Serengeti. June and July are associated with the Western Corridor and northward movement. From July or August through October, the northern Serengeti may offer Mara River activity. The best month depends on the experience you want.
When are the Mara River crossings?
+
Crossings are most commonly associated with July through October, with August and September traditionally considered peak months. Exact dates and locations cannot be predicted.
When is the Serengeti calving season?
+
Calving generally occurs from January through March, with the greatest concentration of births usually in February on the southern short-grass plains.
Where is the best place to see the Great Migration in Africa?
+
It depends on the month. From about January to March, the Ndutu area and southern Serengeti for calving; from April to June, the central Serengeti and Western Corridor; from July to October, the northern Serengeti and Kenya’s Maasai Mara for the Mara River crossings; and in November and December, the eastern and central Serengeti as the herds return south.
How much does a Great Migration safari cost?
+
Every journey is priced to your budget. As a guide, luxury safari camps and lodges typically run from about $1,000 to $3,000 or more per person per night, and most private NndeeAfrika journeys begin at approximately $12,000 per person, excluding international flights. Longer, peak-season or fly-in trips sit above that starting point, and July to October is peak season in the migration areas.
How many wildebeest die during the Great Migration?
+
Estimates vary, but around 250,000 wildebeest are commonly said to die each year during the migration, from predators, exhaustion, disease and the river crossings. A 2017 scientific study of the Mara River estimated that an average of about 6,000 drown there each year, and their remains return vital nutrients to the river.
How far in advance should I book?
+
For July through September, booking 12 to 18 months ahead provides a better selection of well-positioned camps, private vehicles and family accommodation. Other seasons may offer more flexibility, but early planning is still recommended for small, exclusive properties.
Can I combine the migration with other destinations?
+
Yes. Popular combinations include Ngorongoro Crater, Tarangire National Park, gorilla trekking in Rwanda or Uganda, and beach stays in Zanzibar, Seychelles or the Kenyan coast. The combination should be planned around sensible flight connections and enough time in each destination.
