The Great Migration 2026 — Where to Be and When

The Great Migration is the largest overland movement of wildlife on earth. Over 1.5 million wildebeest, 500,000 zebras, and 200,000 gazelles move in a continuous loop between Tanzania's Serengeti and Kenya's Maasai Mara. The most dramatic moment — the Mara River crossings — happens in Kenya between July and October. But every month of the year offers a different chapter of this extraordinary story.

No two years are identical. The wildebeest do not consult a calendar. But the broad pattern of the Migration is consistent, and understanding it is the key to planning a trip around whichever chapter speaks to you most.

The Great Migration Calendar — Month by Month 2026

January and February — The Calving Season, Southern Serengeti, Tanzania

This is one of the most underrated chapters of the Migration. The wildebeest gather in the short-grass plains of the southern Serengeti and Ndutu in enormous numbers to calve. Approximately 500,000 calves are born within a few weeks — the wildebeest's survival strategy is to overwhelm predators with sheer numbers.

For predator viewing, this is extraordinary. Cheetahs, lions, leopards, wild dogs, jackals, and hyenas are all hunting within metres of calving herds. It is chaotic, dramatic, and deeply moving. Best area: Ndutu, Tanzania.

March and April — The Herds Move North, Central Serengeti, Tanzania

The calving is complete and the herds begin moving northwest through the central Serengeti, following the rains and the new grass they stimulate. This is a transitional and often underappreciated period — the Serengeti is lush and green, game viewing is excellent, and crowds are minimal.

May and June — Western Corridor, Serengeti, Tanzania

The herds push into the western Serengeti corridor and begin to congregate near the Grumeti River. The Grumeti has its own crossing moment — smaller than the Mara but genuinely spectacular, with enormous crocodiles that have grown fat waiting for exactly this month each year. Best area: Grumeti, western Serengeti.

By late June the vanguard of the Migration begins entering Kenya. If you are in the Mara in late June, you may see the first herds arriving on the Kenya side.

July — The Mara River Crossings Begin, Maasai Mara, Kenya

This is the month most people picture when they imagine the Great Migration. The wildebeest arrive at the Mara River and face their greatest obstacle — a crossing filled with Nile crocodiles that can exceed four metres in length.

The crossings do not happen on a schedule. A herd may wait at the river bank for days before a leader finally commits, triggering a chaotic rush. You may witness one crossing per day. You may see nothing for three days and then four crossings in a single morning. The unpredictability is part of what makes it unforgettable.

July crossings are typically less numerous than August but the herds are often very large when they do move. Expect busy camps and vehicles at the major crossing points. Best area: Mara River, Maasai Mara, Kenya — particularly the Mara Triangle.

August — Peak Crossing Season, Maasai Mara, Kenya

August is statistically the best month for river crossings. The Mara is at its most dramatic — enormous herds, high predator activity, and frequent crossings as the wildebeest move back and forth across the river responding to where the grass is better.

This is peak season in every sense. Book at least nine months ahead. Expect premium prices at the best camps. It is worth every penny.

September — Crossings Continue, Maasai Mara, Kenya

The crossings continue into September, though the herds begin to sense the rains returning to the south and start to move back toward Tanzania. Early September is still excellent for crossing sightings. By late September the numbers begin to thin.

September is slightly less crowded than August and prices drop marginally. For many guests this represents the best value-to-experience ratio of the entire year.

October — The Return South, Northern Serengeti, Tanzania

The herds cross back into Tanzania through the northern Serengeti. The Mara River crossings reverse direction — still dramatic, but the herds are heading south. The northern Serengeti at this time is exceptional as enormous numbers pass through.

November and December — Dispersal, Southern Serengeti, Tanzania

The herds scatter across the southern Serengeti, responding to the short rains and new grass. Wildlife viewing is good throughout both parks but without the concentrated drama of the July to October period. December sees the first pregnant wildebeest beginning to move toward the calving grounds and the cycle begins again.

Where Exactly Are the River Crossings?

The Mara River crossings happen along a stretch of river within the Maasai Mara National Reserve and private conservancies, primarily in the western Mara Triangle and around the main Mara River crossing points near Serena and Governors.

There is no single crossing point. The wildebeest choose different sections of the river each time based on water levels, crocodile activity, and herd pressure. A good guide who knows the river intimately — and who has a network of other guides communicating via radio — is essential for maximising your chances.

How Long Should You Stay to See a Crossing?

The honest answer: no crossing is guaranteed. However, the statistics are strongly in your favour with a minimum of three nights in the Mara during July through September. Most guests spending four or more nights during this period see at least one crossing.

Doing two nights and hoping to see a crossing is a gamble. If it matters deeply to you, give yourself more time.

Which is Better — Kenya or Tanzania for the Migration?

In short: for the river crossings specifically, Kenya (July to September) is the answer. For calving, Tanzania (January to February). For the full circular journey, a combined Kenya and Tanzania itinerary is the ultimate Migration experience.

How to Book a Great Migration Safari in 2026

The best camps for river crossing viewing have very limited beds. The top choices — Governors' Camp, Sanctuary Olonana, Mahali Mzuri, Lemala Mara, and the private conservancy camps around Naboisho and Olare Motorogi — regularly sell out nine to twelve months ahead for July and August.
