Great Migration Safari Guide: Serengeti & Maasai Mara 2026 | Kenya Safaris | Tanzania Safaris.
The Great Migration safari is the year-round movement of roughly 1.5 million wildebeest and hundreds of thousands of zebra across the Serengeti-Mara ecosystem. Calving happens in Tanzania’s southern Serengeti from January to March; the famous Mara River crossings into Kenya’s Maasai Mara run roughly July to October. There’s no single “best month”; it depends on which phase you want to see, and camps for July–October book out 12–18 months in advance.
Most people picture the Great Migration as one dramatic river crossing, but it’s actually a year-round cycle: roughly 1.5 million wildebeest, alongside zebra, gazelle, and the predators that follow them, move in a loop of an estimated 3,000 km across the Serengeti-Mara ecosystem every year while on a Tanzania safari and Kenya safari. Where the herds are on any given week depends on rainfall, not a fixed date, which is why two safaris booked for the same month can see very different things. This guide breaks the cycle down by phase, compares Serengeti and Maasai Mara for migration viewing, and covers what a trip actually costs and how far ahead to book.
How the Great Migration Actually Works
The herds move clockwise, driven by rain and fresh grass rather than any set calendar, spending roughly nine months a year in Tanzania’s Serengeti and about three months in Kenya’s Maasai Mara. Because it’s weather-driven, no operator can honestly promise a crossing on a specific date; camps track the herds week to week using guide networks and recent sightings, and itineraries sometimes shift a day or two once you’re on the ground.
Great Migration Calendar by Month
January–March, southern Serengeti (Ndutu): Calving season, with hundreds of thousands of calves born within a few weeks and heavy predator activity around the newborns. This is the strongest window for lion and cheetah sightings.
April–June, central and western Serengeti: Herds push north as the long rains ease, with the Grumeti River crossings happening in June–July – smaller crowds than the Mara, but the same crocodile drama.
July–October, northern Serengeti and Maasai Mara: The Mara River crossings, peaking in August and September. This is what most people mean by “the migration”, and it’s the most heavily booked window of the year.
November–December: Herds move back south as the short rains begin, resetting the cycle for the next calving season. Quieter and often better light for photography.
| Phase | Months | Where | Highlight |
|---|---|---|---|
| Calving | Jan–Mar | Southern Serengeti | Predator action, newborn calves |
| Grumeti crossings | Jun–Jul | Western Serengeti | Fewer crowds, big crocodiles |
| Mara River crossings | Jul–Oct | Northern Serengeti / Maasai Mara | Peak drama, peak crowds |
| Return south | Nov–Dec | Central Serengeti | Quieter, good light |
Serengeti or Maasai Mara?
Choose the Serengeti National Park for a longer season (roughly nine months of migration presence, including calving) and more space to spread out; it covers about 14,750 km² against the Maasai Mara’s 1,510 km². Choose the Maasai Mara National Reserve if the Mara River crossing itself is the priority, since the reserve’s smaller size makes crossings more predictable to reach, though also more crowded: it’s common to see well over a hundred vehicles at a popular crossing point in August.
Many travellers with 7+ days do both, crossing the Tanzania-Kenya border partway through the trip to see the ecosystem from each side.
What a Migration Safari Costs
Park fees alone shift with the season. The Maasai Mara’s non-resident entry fee is $100 per person per day from January to June 2026, rising to $200 per day from July to December, a direct reflection of migration demand. Serengeti’s non-resident daily fee runs roughly $70, though it’s worth confirming the exact figure with your operator or TANAPA before booking, since published rates vary by source.
Accommodation moves the total more than park fees do. Camps along the Mara River or in the Serengeti’s Western Corridor during July–September typically charge well above their low-season rates and fill 12–18 months in advance for that window. A packaged safari usually includes park fees, a guide, vehicle, and accommodation; it usually excludes international flights, visas, and extras like a hot-air balloon flight over the plains, which is a popular but separately priced add-on during migration season.
Travellers on a tighter budget can still see strong migration action without July–October pricing: the calving season (January–March) and the Grumeti crossings (June–July) both come with lower rates and thinner crowds.
Sample 8-Day Serengeti & Maasai Mara Itinerary
| Day | Route | Focus |
|---|---|---|
| 1 | Arrive Arusha | Overnight, rest |
| 2–3 | Central Serengeti | Game drives, resident wildlife |
| 4–5 | Northern Serengeti | Migration tracking, possible river activity |
| 6 | Cross to Maasai Mara | Border transfer, afternoon drive |
| 7 | Maasai Mara | Full-day migration and predator viewing |
| 8 | Maasai Mara → Nairobi | Morning drive, transfer out |
Treat this as a template rather than a fixed plan; the actual route should flex around where the herds are reported that week, and cross-border logistics need confirming in advance since vehicle regulations differ between the two countries.
Common Mistakes
The biggest one is treating July–October as a guarantee rather than a probability; herds can run weeks early or late depending on rainfall, and a river crossing is never certain on any given day. The second is booking too late for peak-season camps, which sell out well over a year ahead for the best-positioned properties. A third is picking a single fixed lodge and assuming the migration will come to it, rather than planning a route with enough flexibility to follow where the herds actually are.
When Should You Book?
If you’re targeting July–October, start planning at least 12 months out, longer if you want a specific camp on the Mara River or in the Western Corridor. Calving-season (January–March) and shoulder-season trips can generally be booked with less lead time and still deliver strong wildlife viewing at lower cost.

Plan Your Great Migration Safari
The right camp and route depend entirely on your travel dates and what phase of the migration you want to see: calving, a crossing, or the quieter months in between. Chopper Tour and Travel can build a Serengeti, Maasai Mara, or combined itinerary around your dates, group size, and budget and help you get ahead of the 12-month booking window for peak season.

Frequently Asked Questions
When is the best time to see the Great Migration?
It depends on the experience: January–March for calving in the southern Serengeti, June–July for the Grumeti River crossings, or July–October for the Mara River crossings, which peak in August and September.
Is the migration in Kenya or Tanzania?
Both herds spend about nine months a year in Tanzania’s Serengeti, including calving, and roughly three months (July–October) in Kenya’s Maasai Mara during the crossing period.
Can a river crossing be guaranteed?
No. Crossings depend on where the herds gather that week and can’t be promised on a specific date, even in peak season.
How far ahead should I book?
At least 12 months for July–October travel, especially for camps along the Mara River or Western Corridor, which can book 12–18 months out.
How much does a migration safari cost?
It varies by season and camp category; Maasai Mara park fees alone run $100–$200 per person per day for non-residents in 2026, with accommodation the bigger cost driver during peak months.
Should I choose Serengeti or Maasai Mara?
Serengeti for a longer season and more space, including calving; Maasai Mara for the Mara River crossing itself in a smaller, more concentrated area. Many travellers combine both on a 7+ day trip.
