The Great Wildebeest Migration: When to See It and Where to Position Yourself

The Great Wildebeest Migration is the largest overland mammal movement on Earth. National Geographic’s long-form coverage of the wildebeest migration documents the scale of the crossings in both photography and film — an excellent visual introduction for first-time visitors preparing for what they will witness in person. Each year, more than two million animals — wildebeest, plains zebra and Thomson’s gazelle — follow rainfall and fresh grass across a 1,800-kilometre circuit between Tanzania’s Serengeti and Kenya’s Masai Mara.

The migration has no single start or finish. It is a continuous cycle. Understanding the seasonal rhythm is what separates a spectacular sighting from a missed opportunity.

January to March: Calving Season in the Southern Serengeti

This is one of the most dramatic periods. Around 500,000 calves are born in a six-week window, drawing in lions, cheetahs and hyenas. The Ndutu plains in Tanzania are the place to be. Africa Calling operates mobile camps in this zone during peak calving.

April to May: The Long Rains and the Western Corridor

The herds push north and west across the Serengeti. River crossings begin on the Grumeti River — smaller than the Mara, but equally dramatic. Crowds are thinner during this wetter period, and prices are lower.

July to October: The Mara River Crossings

This is what most travellers picture when they imagine the migration: enormous herds gathering at the Mara River bank, then plunging in while Nile crocodiles wait below. Crossings happen unpredictably — sometimes two a day, sometimes none for a week. The northern Masai Mara, particularly the Mara Triangle, offers the best access to multiple crossing points.

Practical advice: Book river-crossing camps at least six months in advance for July to October. Position yourself at a crossing point by 6:30 a.m. A single crossing can last three hours. Bring a long lens — 400mm minimum.

November to December: The Short Rains and the Return South

The herds begin moving south again as the short rains return to the Serengeti. Fewer tourists, lower prices and comfortable weather make this an underrated time to visit.

Africa Calling’s guides track herd movements daily via radio contact with rangers across both ecosystems. Contact us to build an itinerary around the crossing window that matches your travel dates.

Photography and Practicalities at the Crossing Points

The Mara Triangle, managed by the Mara Conservancy on the western bank of the reserve, controls access to three of the most reliable crossing sites: Crossing Point One near Serena Camp, the Fig Tree crossing to the south, and the crossings along the Purungat Bridge stretch. Guides monitor radio networks from dawn; when herds begin massing on the bank, vehicles position themselves downwind and at a respectful distance. The KWS code of conduct prohibits vehicles from entering the water or creating a barrier that influences herd behaviour.

For photographers, the light is strongest in the morning window (7:00 to 10:00 a.m.), when the sun is behind a vehicle positioned on the Kenyan bank. A full crossing typically produces three to five hours of continuous activity: herds crossing in waves of several hundred, resting, then re-assembling for the next surge. Crocodiles average two to four animals per crossing during peak season. A lens of at least 500mm is recommended if isolating individual animals; 300mm works adequately for herd-wide compositions.

The best complement to a migration safari is the month-by-month seasonal guide for understanding when other ecosystems peak alongside the Mara crossing.

The Kenya Wildlife Service publishes current visitor guidelines for the reserve, and the African Wildlife Foundation maintains updated migration science for those who want deeper ecological background.
