The Ultimate Guide to The Great Migration of Africa

Summary of the Great Migration: Over 2 million animals move annually. Wildebeest, zebra, and gazelles. Serengeti to Masai Mara and back. River crossings peak July to October. Calving season happens January to March. The Mara River crossing is the dramatic highlight. Crocodiles take roughly 10,000 animals yearly. Best viewing from Kenya side July through October.

Is the Mara River crossing worth the wait? I remember sitting by the river for three hours in August, the heat pushing past 35°C, sweat running down my back, watching 50,000 wildebeest stand on the opposite bank doing absolutely nothing. My clients were getting restless. Then one animal—we call it the “Suicide Jumper”—stepped two feet ahead of the herd, looked down at the water, and committed. Within seconds, thousands were pouring into the river like someone had opened a floodgate.

The first thing you notice isn’t the sight. It’s the smell. A mix of wet dust, wild animal musk, and the copper scent of the river. And the noise—it’s not just grunting, it’s a physical vibration in your chest when ten thousand hooves hit the bank at once. Underneath it, the silence of the crocodiles waiting.

The Great Migration of Africa is the largest mammal migration on earth. Every year, roughly 1.5 million wildebeest, 400,000 zebra, and 200,000 gazelles move in a clockwise loop between Tanzania’s Serengeti National Park and Kenya’s Masai Mara National Reserve. They follow the rains. Where rain falls, grass grows. Where grass grows, the herds go.

Why the Migration Happens

I have answered this question dozens of time and my answers is always the same – they migrate to get green pastures (food and water).

The Serengeti’s southern plains dry out after the rains end in May. The grass gets eaten down, water sources shrink. The wildebeest have no choice but to move north where the rains have fallen more recently and the grass is still green.

They’re chasing what we call the “green flush.” You can see them tilting their heads, catching a scent of a thunderstorm that’s still two days away. It’s not a map. It’s instinct. They smell rain from 50 kilometres out and they follow it. By July and August, they’ve reached the Mara River and need to cross into Kenya.

Here’s something guides know: we don’t scan the horizon for wildebeest. We look for dust devils. In the dry season, a massive herd on the move creates a localised dust storm visible from 10+ kilometres away. If you see a tower of red dust that isn’t moving like a whirlwind, that’s your herd.

Following the Rain: Where the Herds Are Throughout the Year

January to March

The herds are in southern Serengeti near Ndutu and the Ngorongoro Conservation Area. This is calving season. Around 8,000 wildebeest calves are born daily during the peak in February.

People obsess over the river crossings, but honestly? The calving season in February is where the real drama happens. In the Ndutu plains, we watch specific prides that have developed tactics for this season. They don’t bother chasing the adults. They just wait by the tall rye grass for the calves to stumble. It’s a grim game of wait and see. Cheetahs work the open flats. Hyenas patrol at night. It’s a predator’s paradise.

April to May

Mating season. The herds start moving northwest through central Serengeti toward the Western Corridor. The long rains make some roads difficult. Fewer tourists, lower prices, but the action is less concentrated.

June

The herds reach the Grumeti River in western Serengeti. The first river crossings happen here. Less dramatic than the Mara crossings but still impressive.

One thing about the Grumeti region: avoid wearing dark blue or black. These colours are magnets for Tsetse flies, and their bite feels like a hot needle. Stick to khaki and light greens.

July to August

Yes, the crossings are big, but the safari traffic jams at the river are maddening. Thirty vehicles deep at Serena crossing, engines idling, tourists jostling for position. If you want the migration without the circus, come in late September. The river is still there, the crocs are still hungry, but the crowds have gone home.

That said, August is when the crossings are most frequent. This is what most people come to see. Some days nothing happens. Some days you witness 50,000 animals cross in a single morning.

Don’t just watch—listen. The migration sounds like a massive, out-of-tune choir of low-pitched grunting. Guides call it the “Gnu” sound. If you’re in a thicket and can’t see the plains, the vibration of the grunting tells you how many thousands are nearby.

September to October

The herds are scattered across the Masai Mara grazing. Crossings still happen but less frequently. The grass is short from grazing, making wildlife easier to spot. Lions are fat and lazy from weeks of easy hunting.

This is actually my favourite time in the Mara. Fewer vehicles at crossing points, excellent predator activity, and the herds are already there.

November to December

The herds begin moving south again, back toward Tanzania. The return crossings are less dramatic because the wildebeest aren’t bunched up. They drift back in smaller groups over several weeks.

Local guides often prefer the Lobo area in Northern Serengeti during October/November. It’s a bottleneck with incredible rock formations where you can see the migration against a dramatic backdrop with 90% fewer cars.

The Great Migration River Crossings

The Mara River crossings are what everyone wants to see. And I’ll be honest: there’s no guarantee you’ll witness one.

The wildebeest are unpredictable. They gather on the riverbank, sometimes 50,000 strong, and then… nothing. They turn around and graze. Come back hours later. Leave again.

Most tourists tell their driver to “find the crossing.” Bad idea. If you drive around looking for a crossing that’s already started, you’ll arrive at a car park of 50 vehicles. Better to find a good spot where the herd is gathering and stay put. You get the front row when it finally breaks.

Watch for the Suicide Jumper. The herd can wait for days, but once that first animal commits, a herd mentality takes over that’s impossible to stop. If you see one animal standing ahead of the rest, looking down at the water—get your camera ready.

Note from the field: If your driver tries to park right on the lip of the bank before the first animal jumps, tell him to back up. If the scouts see a vehicle too close, they’ll spook, and you’ll sit there for another four hours for nothing. Patience pays. Aggression loses the shot.

Main Crossing Points in the Mara

Lookout Hill Crossing – One of the first points used when herds enter from Tanzania. Usually active early August.

Cul de Sac Crossing – Famous for its narrow channel. Dramatic pile-ups, high crocodile activity.

Serena’s Crossing – Consistent and accessible. Popular with tourists, which means vehicle congestion during peak season.

Kichwa Tembo Crossing – Later in the season when herds head back south. Quieter, less dramatic.

If you want to find a crossing that already happened—to see the aftermath and predators—look for Marabou Storks and vultures circling a specific river bend. They’re the clean-up crew for animals that didn’t survive the current.

Where to Stay for the Great Migration

Kenya Side (Masai Mara)

For River Crossings: Stay in the Mara Triangle or northern Mara near the river. Kichwa Tembo, Angama Mara, Governors’ Camp are positioned well. Expect $400-800 per person per night during peak season.

For Value: Lodges in Talek area are cheaper but further from main crossing points. If you’re staying in Talek to save money, just know you’ll be waking up an hour earlier than everyone else to beat the traffic to the river. After heavy rain, the black cotton soil between Talek and Sekenani gate turns into a nightmare—I’ve spent two hours winching vehicles out of that mud. It’s a trade-off. Rates start around $150-200 per person per night.

For Luxury: Angama Mara sits on the escarpment with views across the entire reserve. $1,200+ per person per night.

Tanzania Side (Serengeti)

Mobile camps follow the migration. They literally pack up and move to wherever the herds are. Expensive but you’re guaranteed proximity to the action.

Demerits of Wildebeest Migration

What safari operators in Kenya and Tanzania won’t tell you, unless you ask, is that things can go wrong when you come for a migration safari in Africa. Here are some of the thinngs can make your safari a total failure.

“We didn’t see a crossing”

This happens. The migration is unpredictable. I had a family in August spend four days in the Mara without witnessing a single crossing. The herds were there, spread across the plains, but they weren’t crossing.

How to reduce this risk: Book at least 4-5 days during peak season. The more days you have, the better your odds.

“Too many vehicles”

During August, popular crossing points can have 30-40 vehicles lined up.

How to reduce this risk: Stay in private conservancies (Olare Motorogi, Naboisho, Mara North) that border the reserve. Vehicle numbers are limited. Or visit late September/early October when crowds thin.

“The food was disappointing”

A common complaint is the “stale safari box.” Ask your camp specifically for a “cooked bush breakfast” or a “freshly packed lunch” rather than the standard pre-packed box. If you don’t ask, you often get leftover buffet food from the night before.

“My phone died”

The heat inside a stationary safari vehicle while waiting for a crossing can exceed 40°C. Lithium power banks overheat and shut down. Keep your tech in an insulated cool bag to maintain operating temperature.

“I only brought one pair of binoculars”

During a crossing, things happen in three places at once: the entry, the middle (crocs), and the exit (predators). If you’re sharing binoculars, you’ll miss the kill or the climb. Bring enough for everyone.

What I Tell First-Timers

Never fly home directly from a migration safari. The dust, the 5am wake-ups, the sensory overload—safari fatigue is real. Book 3 days in Zanzibar or Diani Beach afterward to decompress.

Also: bring a good zoom lens. The crossings happen on the opposite riverbank half the time. A 200mm minimum, 400mm ideal. And pack a Dormans coffee sachet or two if you’re particular about your morning brew—camp coffee can be hit or miss, especially at the budget places near Aitong village.
