Saskia The Great Migration is one of the most extraordinary wildlife spectacles on Earth — and Tanzania gives you a front-row seat. Every year, more than 1.5 million wildebeest, 200,000 zebras, and thousands of gazelles make a dramatic, circular journey across the Serengeti ecosystem, driven by rain and the search for greener pastures.
From river crossings to calving season, witnessing the Great Migration is an unforgettable travel experience—and one of the top reasons people go on safari in Tanzania.
In this guide, you’ll learn what the Great Migration is, why it’s worth seeing, when and where to go, and how Tanzania compares to Kenya’s Maasai Mara for migration viewing.

What Is the Great Migration?
The Great Migration is a year-round, clockwise movement of herbivores between Tanzania’s Serengeti National Park and Kenya’s Maasai Mara Reserve. Following seasonal rains, huge herds move across the plains in search of fresh grazing land.
The migration includes:
- Calving season in the southern Serengeti
- Dramatic river crossings over the Grumeti and Mara Rivers
- Predator encounters with lions, cheetahs, and crocodiles
- A constant cycle of birth, death, movement, and survival
If you’re fascinated by wildlife behavior, it’s worth reading my Wildlife Guide to Tanzania, which breaks down what animals to expect and when.
Why Is the Great Migration Worth Seeing?
The Great Migration is not only the largest land-based animal migration in the world, but also one of the most emotionally stirring.
- Mass movement: Witness hundreds of thousands of animals moving across the plains
- Predator action: Lions, hyenas, and crocs create National Geographic-worthy drama
- Seasonal beauty: See the Serengeti in bloom or bone-dry, depending on the time of year
- Cultural insight: Combine your wildlife viewing with cultural activities in Tanzania for a richer experience
For couples, this can be the highlight of a honeymoon in Tanzania. For families, it’s one of the most powerful kid-friendly safari moments.
