The Greatest Wildlife Spectacle on Earth
Great Wildebeest
Migration Calendar
2 million wildebeest. One circular route. 12 months of where the herds are, when the rivers run with crossings, and how to plan a migration safari with the family-owned operator that has been reading these herds since 1978.
The basics
What Is the Great Wildebeest Migration?
The Great Wildebeest Migration is the largest mammal movement on earth. Every year, approximately 2 million wildebeest, 250,000 zebra, and 500,000 Thomson's and Grant's gazelle complete a continuous circular journey through the Serengeti-Mara ecosystem — chasing the rains and the fresh grass that follows them. The single round trip covers roughly 800 km. From an aircraft, the herds darken the plains in a moving carpet that can take an entire day to pass a single point.
It is not a straight line. The wildebeest follow a roughly circular route across 30,000 km² of Tanzania and Kenya. They move from the short-grass plains of the southern Serengeti in January, northwest through the central Serengeti from March, funnel into the western corridor by May and June, reach the Mara River in the far north by July, cross into Kenya's Masai Mara, and loop back south through October and November. Every animal completes the loop — there is no shortcut, no terminus. The migration is a continuous clockwise circuit, never stopping, never ending.
There is no single event — no start date, no finish line. The herds are always somewhere in the ecosystem. What changes month by month is which part of the Serengeti you need to be in. In January, that is Ndutu in the south. In August, it is the Mara River in the far north. A good guide knows where to position you.
Safaris Tanzania has been tracking this movement since 1978. When we tell you where the herds are, we have seen them there. That is the difference between booking with a ground operator — vehicles, guides, and lodges we own or have worked with for 20+ years — and booking with an agent who has never been on a game drive.
Why book direct
Why See the Migration with Safaris Tanzania?
48 Years Reading the Herds
Kassim Abdallah has observed the migration in 45+ consecutive years. He knows where the herds are before the guidebooks do — and which lodges have resident guides versus seasonal hires.
Own Vehicles, Own Guides
We own our fleet of 4x4 Toyota Land Cruisers (pop-top, charging ports, fridge) and employ our guides full-time. No third-party brokers, no-commission drivers. You deal directly with the operator — and we adjust your itinerary if the herds have moved.
Real-Time Positioning
We monitor the herds in real time through our network of driver-guides across the Serengeti ecosystem. If the migration is 40 km further south than expected, your guide knows before you reach the planned camp.
Transparent Pricing
We show our prices. No inquiry form required. From $1,456 for a 5-day northern circuit, including park fees, accommodation, vehicle, guide, and meals. Foreign-agent markups of 20–30% are not built in.
When to go
Migration Calendar: Month by Month
Below is the working month-by-month calendar. Migration timing shifts 2–4 weeks each year based on rainfall. Safaris Tanzania monitors the herds in real time and adjusts your itinerary accordingly.
| Month | Where the herds are | Rating | Predators | Crossings / Calving | Notes |
|---|---|---|---|---|---|
| January | Southern Serengeti / Ndutu (Lake Ndutu / Lake Masek) | Very high | None — calving zone Peak (week 3–4 of January is heaviest) | Short-grass plains east of Seronera. 8,000+ calves per day at peak. Predator density: highest of the year. Cheetah sightings exceptional. Early starts — game drives depart 5:30am. | |
| February | Ndutu / Southern Plains | Very high | None Tapering (last calves mid-month) | Same plains as January but light is hotter. Best big-cat photography of the year — lions on the move, cheetah coalitions, hyena clan activity. Calves now 6–8 weeks old and starting to run with herds. | |
| March | Central Serengeti / Seronera | High | None Done — calves moving with herds | Long rains begin mid-March. Plains turn emerald green. Herds start north. The Seronera Valley has the highest leopard density in Africa — good time to combine migration scouting with resident big cats. Lower prices. | |
| April | Western Corridor approaches / Loliondo | Moderate | None yet — | Long rains in full. Lowest prices of the year. Virtually no other vehicles. Photographers prize the green-season light and dramatic skies. Some lodges close for the month. Best for: budget travelers, photographers, repeat visitors. | |
| May | Western Corridor / Grumeti River | Moderate | Grumeti crossings begin (irregular) — | Grumeti River crossings open the river-crossing season. Less famous than the Mara but equally dramatic, and often you are the only vehicle. The Grumeti is wider and shallower than the Mara — easier crossings, larger Nile crocodiles. | |
| June | Grumeti / Northern approaches | Moderate–High | Grumeti crossings peak (mid-month) — | The herds funnel toward the Mara River. Grumeti crossings continue but the northern Serengeti is the focus. Long days: 12+ hours of usable light. Cooler nights (10–14°C at altitude). Excellent predator viewing — lion prides hunt the stragglers. | |
| July | Northern Serengeti / Mara River (Lamai Wedge) | High | First Mara River crossings (often last week of July) — | The great spectacle starts. First crossings typically late July. The Lamai Wedge (sand river north of the Mara) is the densest crossing area. Position: Kogatende or Lamai airstrip in / out by bush plane. 3 nights minimum needed. | |
| August | Northern Serengeti / Mara River | High | Peak crossings — multiple per day — | The migration is at its zenith. Daily crossings are normal; some days the river is full of wildebeest. Camps in the Mara River area book out 9–12 months ahead. Book now for next August. 4 nights recommended to guarantee at least one crossing. | |
| September | Northern Serengeti / Mara River / Loita Plains | High | Crossings continue, herds begin south push — | Last reliable month for Mara River crossings. Some herds push into Kenya's Masai Mara. Fewer vehicles than August at crossing points. Combine with a 2-night Manyara or Tarangire extension for diversity. | |
| October | Central Serengeti / Seronera / Naabi Hill | High (resident) | — — | Herds return south. Short rains begin late October, reviving the plains. Resident Seronera predators (leopards in the fever trees, lion prides on the kopjes, cheetah on the open grasslands) are at their best. Lower prices than August/September. | |
| November | Central / Southern Serengeti / Ndutu approaches | Moderate–High | — — | Short rains in full. Empty parks. Newborn impalas (their own birthing season). Exceptional value — high-end lodges at low-season rates. The migration is dispersed but on the move south. Good for the second safari of the year. | |
| December | Southern Plains / Ndutu (calving zone) | High | — First calves late December | Herds building near Ndutu again. Festive-season rates apply (15–20% premium). The calving season is about to start in earnest — book January or February for the peak. |
Where to go
Four Key Areas for Wildebeest Migration Safaris
Ndutu / Southern Serengeti (Calving Zone)
December – MarchThe calving grounds. Approximately 500,000 wildebeest calves are born here between December and March, with up to 8,000 calves hitting the ground on a single peak day. The density of newborns draws extraordinary concentrations of predators — lionesses with full bellies, cheetah coalitions teaching cubs to hunt, hyena clans, and the smaller cats. The short-grass plains east of Seronera are also the least-crowded of the migration zones: two vehicles at a sighting is busy.
From $1,456 pp for 5 days
View SafariNorthern Serengeti / Mara River (Crossing Zone)
July – OctoberThe famous crossings. Over a million wildebeest must cross the Mara River to reach the northern grazing grounds, and the spectacle is the single most-photographed wildlife event on earth. Crossings are unpredictable — sometimes three in a day, sometimes nothing for a week — but when they happen, nothing else in African wildlife compares. Multiple crossing points along a 60 km stretch of river reduce crowding; unlike Kenya's Masai Mara where 50+ vehicles can be at a single crossing, Tanzania's northern Serengeti remains relatively quiet.
From $1,872 pp for 7 days
View Safari
Western Corridor / Grumeti (Opening Act)
May – JulyThe opening act. Grumeti River crossings (May to July) are less famous than the Mara but equally dramatic — and far fewer vehicles. The Grumeti is wider and shallower than the Mara, with longer river crossings and larger Nile crocodiles (some specimens over 5 metres have been recorded here). The western corridor also has the best cheetah viewing in the ecosystem. Position: Kirawira or Grumeti Reserve tented camps.
From $1,248 pp for 5 days
View Safari
Central Serengeti / Seronera (Resident Wildlife + Pass-Through)
Year-round resident wildlife (herds pass through Mar–Jun and Oct–Dec)The hub of the Serengeti. Big cats are resident year-round — leopards in the fever trees along the Seronera River, lion prides on the kopjes (rock outcrops), cheetah on the open plains. The migration passes through in March–June (heading north) and October–December (heading south), and the resident predators are active around the herds in both windows. Combine Seronera with a 2-night northern or southern extension for a full migration trip.

Mara River Crossing Points — Where the Drama Happens
The Mara River runs along the northern Serengeti's border with Kenya. There are multiple crossing points along a 60 km stretch — each with its own character, crowd level, and best viewing window. Most safaris stay in one area; the best migrate between two.
| Crossing Point | Best Time | Crowd Level | Notes |
|---|---|---|---|
| Lamai Wedge | Late July – early September | Moderate | Sand-river confluence north of the Mara. Highest density of crossings. The Lamai is the place to be for the start of the season. Access via Kogatende airstrip. |
| Mara River Tented Camp crossing | August | Moderate–High | Single, dramatic crossing point with a permanent camp overlooking the river. Most-photographed crossing site. Book lodge 9–12 months ahead for August. |
| Kogatende area | August – September | Low–Moderate | Multiple smaller crossing points along 20 km of river. More vehicles than Lamai Wedge in peak August, but multiple alternatives if one crossing is busy. |
| Lookout Hill | August | High | Panoramic viewpoint above the river. Can host 10–15 vehicles at a single crossing. Less intimate but the views are unmatched for landscape photography. |
| Sand River (Kenya/Tanzania border) | September – October | Low | The return crossing — when herds push back south. Often missed because the migration is associated with the north push, but the south push has its own drama and far fewer visitors. |
On the riverbank
What to Expect at a Mara River Crossing
A river crossing is not a single moment — it is a sequence that can take 30 to 90 minutes from the first scout to the last animal over. Knowing the sequence helps you know when to have the camera up.
Phase 1 — the build-up (often 30–60 minutes). A few hundred wildebeest mass on the riverbank. They pace forward, then back. They jostle, lowing and snorting. The river is audible in the stillness. Hyenas and lions watch from the high bank. A lone wildebeest breaks forward, then retreats. You and your guide are 50–80 metres away, engine off, on the high bank.
Phase 2 — the leap (10–90 seconds). One animal — usually a single brave wildebeest, sometimes a tight group of 20 — commits. The bank is steep, 3–5 metres of vertical drop, and the animal launches. Within seconds, dozens are falling. The river explodes. The crocodile strike (if it happens) is silent and fast. You are firing off frames at 10 fps and hoping one of them captures the chaos.
Phase 3 — the crush (15–30 minutes). Hundreds of wildebeest pour into the river at once, pushing those already in forward. Animals on the opposite bank turn back when they see the volume. Bodies press against bodies. Some animals are swept downstream; some climb on top of others. The river can run red with mud. The noise is extraordinary.
Phase 4 — the dispersal (20–40 minutes). Survivors reach the far bank and pause, shaking water from their coats. Predators move toward the stragglers. Hyenas move to the river's edge. The herd reforms on the far side and moves north, away from the river. Your guide starts the engine. You have just witnessed the migration.
Practical tip: Crossings are most common between 10am and 2pm in the northern Serengeti — though they can happen at any time of day. The single best predictor is the position of the herd on the morning of a game drive: a tight cluster on the riverbank at 8am is a strong sign a crossing is coming. Ask your guide at morning coffee.
Behind the lens
Photographing the Migration — Gear, Light, Positioning
The migration is one of the most-photographed wildlife events on earth, and getting strong images is more about positioning and timing than gear. A 200mm lens on a mid-range body will produce better photos than a 600mm lens used from the wrong spot. That said, here is the working setup our guides recommend for travelers who shoot seriously.
Lens choice. 100–400mm zoom is the workhorse — wide enough for a herd on the move, long enough for a single wildebeest mid-leap. A 600mm prime or 150–600mm zoom is the dedicated crossing lens, but you will not use it for predator or landscape work. Bring both if you can; rent locally in Arusha if you cannot.
Shutter speed. 1/2000s minimum for crossings, 1/1600s for predator action, 1/500s for landscape-with-herds. Faster is better — under-expose and recover in post rather than risk motion blur.
Aperture. f/5.6 to f/8 for single subjects (sharp on the eye, soft background), f/11 for herds in motion (front-to-back sharpness).
Light windows. The first 90 minutes after sunrise (5:45–7:15am) and the last 90 before sunset (5:30–7:00pm) are the gold. Calving-zone photography is best in the early morning when the herds are active and the light is warm. Crossings are most common in the middle of the day when the light is harsh — use a higher ISO and accept some noise.
Positioning. Stay on the high bank, 50–80 metres from the river. Approach the bank slowly and quietly — your guide knows the line. Once parked, switch off the engine. Do not stand in the vehicle (most camps prohibit it during crossings). Frame the action and wait for the herd to commit.
What to leave behind. Tripods (no time to set up at a crossing), heavy telephotos that are not 100–400mm or longer, drones (TANAPA prohibits them in all national parks without a permit, and crossing events are too unpredictable for drone use).
Backup plan. Bring 2 camera bodies if you can. Dust is the constant enemy in the Serengeti — keep a rocket blower and microfiber cloth in your bag, and a rain cover for the long-rain shoulder seasons.
Beyond the spectacle
The Migration in 2026: Conservation Status and What Supports It
The migration is currently stable in population terms. Counts in 2024 and 2025 confirmed around 1.5 million wildebeest, 250,000 zebra, and 500,000 Thomson's and Grant's gazelle participating in the loop. That is below the 1990s peak of 1.7 million wildebeest (the ecosystem can support more in good-rainfall years), but it is well above the crisis levels of the 1980s when rinderpest and poaching nearly halved the herds.
The main threats to the migration in 2026 are habitat fragmentation, climate variability, and poaching.
Habitat fragmentation is the most discussed threat. A proposed highway and a railway line across the northern Serengeti corridor have been on the drawing board for over a decade. Both would create permanent barriers between the southern Serengeti (calving zone) and the northern Serengeti (Mara River crossings), cutting the circular route in two. As of 2026, neither project has broken ground, but the plans remain active. The Serengeti ecosystem is also bordered by expanding agriculture on its western edge (around the Grumeti and Ikorongo reserves) and to the south (in the Loliondo and Ngorongoro Conservation Area borderlands). Tanzania National Parks Authority (TANAPA) and the Frankfurt Zoological Society maintain the buffer zones that currently hold the line.
Climate variability is shifting the calving window. Herds have moved calving 2–3 weeks later on average over the last decade, with the short rains in October–December less reliable than they were in the 1990s. The migration's circular route is essentially a search for grass following rain — and when rain patterns shift, the migration shifts with them. The 2025 long rains were 18% below the 30-year average, pushing the herds' southern Serengeti arrival into late January. The 2026 long rains are forecast to be normal to above-normal, which means a more typical calving window.
Poaching is at near-zero levels in the core Serengeti zones. The Serengeti Anti-Poaching Unit (SAPU) and TANAPA rangers run 24/7 patrols across the 14,763 km² ecosystem. Snaring is the primary remaining threat (larger carnivores and ungulates caught accidentally), and snare-removal sweeps have reduced snares found per patrol from 1.4 (2018) to 0.3 (2025). The single best anti-poaching intervention is tourism revenue — roughly 70% of every park-fee dollar goes back to TANAPA wildlife management. Booking a safari directly with a Tanzania-registered operator, paying the published park fees, and staying in TATO-registered lodges is the most effective way for travelers to support the migration's survival.
Safaris Tanzania is a TATO-registered operator, and we have been part of the Serengeti ecosystem since 1978. We pay all park fees in full, employ our guides on permanent contracts, and contribute to community conservation projects in the Loliondo and Grumeti areas. The migration is not just a product we sell — it is the landscape our family has lived alongside for 48 years.
The three ecosystems
Northern, Western, and Southern Serengeti — Three Zones Compared
The Serengeti is not one ecosystem — it is three connected ecosystems, each with its own landscape, wildlife profile, and migration phase. Most travelers see only one; a complete migration circuit visits all three. The table below compares the practical differences for planning a 2026 safari.
| Factor | Southern / Ndutu | Western / Grumeti | Northern / Mara River |
|---|---|---|---|
| Migration phase | Calving (Dec–Mar) — 500,000 calves over 6 weeks | Opening crossings (May–Jul) — Grumeti River | Main crossings (Jul–Oct) — Mara River |
| Landscape | Short-grass plains, soda lakes (Ndutu, Masek) | Wooded savanna, Grumeti River woodland corridor | Open riverine forest, sand-river confluences |
| Signature species | Wildebeest, zebra, lions on plains, cheetah | Wildebeest, large Nile crocodiles, cheetah, colobus monkey | Wildebeest, hippo pools, leopard along river, hyena clans |
| Crowd level (peak) | Moderate — December/January fills, otherwise low | Low — often only your vehicle at a crossing | Moderate–High — Lookout Hill and Mara River Tented Camp busy in August |
| Access from Arusha | Ndutu airstrip (1h), or drive via Ngorongoro (5h) | Kirawira / Grumeti airstrip (1h 30m), or drive via Seronera (4h) | Kogatende / Lamai airstrip (1h 45m), or drive via Seronera (3h 30m) |
| Recommended nights | 3 nights (calving) | 2 nights (crossings) | 3–4 nights (crossings) — 4 nights to guarantee a crossing |
| Cost (per person, mid-range, full board) | $350–$520/night (Jan–Feb peak) | $380–$560/night (May–Jul shoulder) | $450–$850/night (Aug–Sep peak) |
| Best for | Photographers, predator-prey action, first-time visitors, January–February trips | Repeat visitors, photographers who want exclusive crossings, value-seekers (May–June) | Once-in-a-lifetime experience, photographers, travelers who can plan 9–12 months ahead |
Combining two zones in one trip (e.g. southern calving + northern crossings) requires 10+ nights and a bush-plane transfer between Ndutu and Kogatende. Safaris Tanzania handles the logistics — your guide hands you off at the connecting airstrip.
Where to stay
Migration Zone Accommodation — Three Tiers Compared
All rates include full board (breakfast, lunch, dinner, drinks), game drives, park fees, and transfers. The single biggest differentiator at the migration zones is vehicle access — the northern Serengeti camps with private vehicle options give you the most flexibility for crossing days.
| Tier | Price (per person, per night) | Examples | Best For | Booking Lead Time |
|---|---|---|---|---|
| Tented Safari Camp | $180–$280 per person per night | Lemala Ndutu, Kirawira Tented, Serengeti Savannah Camp | Photographers, mid-range budgets, close-to-nature experience | Book 6–9 months ahead for August/September northern Serengeti |
| Mid-Range Safari Lodge | $280–$420 per person per night | Serengeti Serena, Sopa Lodge, Asanja Moru (all TATO-registered) | First-time safari travelers, families, value for comfort | Book 4–6 months ahead for peak season (July–September) |
| Boutique / Permanent Tented | $450–$850 per person per night | Sayari Camp, Lemala Ewanjan, Mwiba Lodge | Honeymooners, photography-focused travelers, repeat visitors | Book 9–12 months ahead for August/September migration |
All rates reflect 2026 season pricing. Peak-season surcharges (15–20%) apply for festive season (20 Dec – 5 Jan) and Easter.

Tanzania vs Kenya — Where to See the Migration
The migration crosses both Tanzania and Kenya, but the two ecosystems are very different. The table below summarizes the key differences for travelers planning a 2026 migration safari.
| Factor | Tanzania (Serengeti) | Kenya (Masai Mara) |
|---|---|---|
| Ecosystem size | 14,763 km² continuous ecosystem. Herds spread across vast territory — fewer vehicles, no crowding. | 1,510 km². Herds concentrate in a fraction of that space during crossings. |
| Migration access | Herd movement across a vast territory year-round. Multiple crossing points along a 60 km stretch of the Mara River. | Herds concentrate at 2–3 known crossing points. Can have 50+ vehicles at a single crossing. |
| Season length | Crossings July–October — 4-month window with options. Herds present in Tanzania for 8+ months of the year. | Masai Mara crossings often concentrated in 6–8 weeks in August–September. |
| Combined circuits | Add Ngorongoro Crater, Tarangire, Ndutu calving to the same trip. | Limited to Masai Mara and northern Kenya circuit only. |
| Park fees (international adult, 2026) | Serengeti: $70/day + Ngorongoro: $70/day. Total park fees for 7-day Serengeti trip: $490 per person. | Masai Mara: $80/day. Total for 7-day Mara-only trip: $560 per person. |
| Best suited for | First-time migration visitors, photographers, travelers combining calving with crossings, longer trips. | Short-stay visitors (3–4 nights), travelers pairing with a beach extension in Mombasa or Zanzibar via Nairobi. |
The 2026 long-rain forecast is normal to above-normal — a typical calving window is expected. Cross-bookings between the two countries are possible but require a multi-entry visa and an extra $200–$300 per person in road or air transfers.
