Great Migration: Calving (Jan–Mar) vs River Crossings (Jul–Oct)

Every year, over 1.5 million wildebeest move across the Serengeti in a spectacular cycle known as the Great Wildebeest Migration. But the experience changes dramatically depending on when and where you go.
The Calving Season and the River Crossing Season are the two highlights of this natural wonder — each offering different thrills, moods, and photographic rewards.

If you’re wondering which one to choose, this guide will help you decide when to witness your wow moment in Tanzania.

The Answer is Short And Clear.

• Choose the Calving Season (January–March) if you love drama, intimacy, and photography. It’s the season of new life — when half a million wildebeest calves are born on the lush plains of Ndutu, in the Southern Serengeti. Predators are everywhere, and light is soft and beautiful for photos.

• Choose the River Crossing Season (July–October) if you crave adrenaline, action, and intensity. The herds gather in the Northern Serengeti, facing crocodile-infested rivers and predators waiting along the banks. It’s a thrilling spectacle that defines the true wild spirit of Africa.

Both are extraordinary — the difference lies in what kind of story you want your safari to tell.

What You’ll See

Calving Season (January–March – Ndutu, Southern Serengeti)

• Over 500,000 wildebeest births within a few weeks.

• Cheetahs and lions hunting across open plains.

• Soft light and green landscapes — ideal for photographers.

• Easy access from Arusha and short flights to Ndutu Airstrip.

• Excellent for families and photographers seeking calmer conditions.

During this time, the southern plains bloom with new grass, drawing vast herds. It’s peaceful, yet full of life and predator-prey encounters that unfold in open view.

River Crossing Season (July–October – Northern Serengeti)

• Mara River crossings — the most dramatic moment of the Migration.

• Intense predator action: lions, crocodiles, and hyenas on the hunt.

• Dry weather and perfect visibility for long game drives.

• Fewer camps, higher demand — early booking essential.

• Ideal for those who want raw drama and once-in-a-lifetime scenes.

The crossings are unpredictable — they can happen any day, any hour. But when they do, they’re unforgettable: thundering hooves, swirling dust, and pure instinct in motion.

Weather & Travel Practicalities

• Calving Season (Jan–Mar): Warm days, some afternoon rain, and lush green landscapes. Roads may be damp, but travel is easy with 4×4 vehicles. Flights connect Ndutu from Arusha and the Serengeti.

• River Crossings (Jul–Oct): Dry and sunny with cooler mornings. Roads are smooth, skies are clear, and photography conditions are perfect. Travel time is longer, but airstrips like Kogatende make access simple.

Both seasons offer comfortable temperatures, with the green season feeling more peaceful and the dry season feeling more adventurous.

Budget & Availability

• Calving Season: Mid-range pricing, more lodge availability, and great value. Camps like Kon Tiki Ndutu or Tukaone Weaver provide front-row access to the herds.

• River Crossings: Peak season rates and limited space. Camps in Northern Serengeti (like Kon Tiki Serengeti Camp) often book up a year ahead.

If you want the drama of the crossings, plan early.
If you prefer fewer crowds and excellent photography at lower cost, go for calving season.
