The greatest show on the savanna

Each year, more than a million wildebeest, along with zebra and gazelle, follow the rains in a great loop through Tanzania’s Serengeti and Kenya’s Maasai Mara.

The year begins in the southern Serengeti, where the herds give birth in the short-grass plains, usually from January to March. As the grass dries, they move west and north, and by mid-year they reach the Mara River, which runs along the border between the two countries.

From about July to October, the herds cross the river, sometimes again and again, chasing fresh grass on the other side. These crossings are the moment travelers dream about, and they’re one of the most dramatic wildlife scenes on earth.

What a crossing is really like

No one can schedule a crossing, and that’s part of what makes it unforgettable.

The herds gather at the riverbank, sometimes for hours, sometimes for days, pacing and hesitating. Then one animal goes, and suddenly thousands follow, leaping down the banks into the water while the dust rises behind them. Crocodiles wait in the river, and the whole scene is over in minutes, or goes on for an hour.

Your guide reads the herds, watches where they’re gathering and decides when to wait. The best days often look like this: an early start, a packed breakfast, a quiet spot above the river and a lot of patience. Even the waiting is part of the magic, with lions, elephants and giraffes going about their day around you.

Where to see it

Both sides of the river offer crossings. Where you stay shapes how many other vehicles you’ll share them with.

Kenya’s famous reserve, with big cats year-round and crossings along the river from about July to October.

Good to know

The small things that make a migration safari feel easy.

Pack soft and light

Bush flights have strict weight limits, often around 15 kilograms including your carry-on, and bags need to be soft-sided.

Dress in layers

Mornings and evenings are cool in an open vehicle, and afternoons warm up fast. Neutral colors work best.

Bring binoculars

A good pair for each traveler makes a huge difference, especially when the herds are gathering on the far bank.

Book early for peak weeks

The camps closest to the river book up well ahead for July through September. Planning a year out gives you the best choice.

Plan two camps

Pairing a river camp with a second area, like a conservancy or the Serengeti plains, gives you more than one chance at the herds.

Talk to a travel clinic

Ask your doctor or a travel clinic about vaccines and malaria precautions well before you go.
