Every year, over two million wildebeest, zebras, and gazelles trek across the vast plains of East Africa in search of fresh pasture and water. Known as the Great Migration, this awe-inspiring event is often called the “Greatest Wildlife Show on Earth.”
While many travelers assume the migration is a single event that happens at one specific time, it is actually a continuous, year-round circular journey. Because the herds are constantly moving across the Serengeti ecosystem in Tanzania, where you should go depends entirely on when you plan to visit.
If you are planning a bucket-list safari, here is your complete month-by-month guide to the best Great Migration viewing locations in Tanzania throughout the year.
January to March: Southern Serengeti & Ndutu (The Calving Season)
If you want to witness new life and intense predator action, visiting during the first quarter of the year is ideal.
Where the Herds Are
During these months, the mega-herds settle on the nutrient-rich short-grass plains of the Southern Serengeti and the Ndutu region (within the Ngorongoro Conservation Area).
What You Will Experience
- The Birth of New Life: Around February, synchronized calving occurs, with over 8,000 wildebeest calves born every single day over a two-to-three-week period.
- High Predator Activity: Lions, cheetahs, leopards, and hyenas gather in large numbers to hunt vulnerable newborn calves. The open plains offer unobstructed, dramatic views of these hunts.
- Lush Landscapes: This period coincides with green scenery, excellent birdwatching, and slightly lower park crowds compared to the river crossing season.
April to May: Central Serengeti & Western Corridor (The Journey North)
As the southern plains dry out and food becomes scarce, the herds begin their trek northwest toward the central and western parts of the Serengeti.
Where the Herds Are
The animals move through the Seronera Valley (Central Serengeti) and begin fanning out into the Western Corridor near the Grumeti River.
What You Will Experience
- The “Green Season”: April and May mark Tanzania’s heavy rains. While roads can be muddy, the landscape is vibrant green, and accommodation rates drop significantly.
- Fewer Tourists: If you prefer a quiet safari experience without safari vehicles crowding the view, this is the best time to go.
- Massive Column Movements: You will see long, striking columns of thousands of animals moving steadily across the central valleys.
June to July: Western Serengeti & The Grumeti River Crossings
By June, the rains subside, and the herds reach their first major natural obstacle on their northern march.
Where the Herds Are
The herds concentrate heavily in the Western Serengeti along the banks of the Grumeti River.
What You Will Experience
- The First River Crossings: Before facing the famous Mara River, the herds must cross the Grumeti. These waters are inhabited by some of Africa’s largest Nile crocodiles.
- Rutting Season: June is also the mating season for wildebeest. The plains come alive with territorial displays and noisy interactions among the males.
- Private Reserves: Many camps in the Grumeti area are located in private concessions, allowing for off-road game drives and guided walking safaris.
August to October: Northern Serengeti (The Iconic Mara River Crossings)
This is the most famous phase of the Great Migration, featured in countless nature documentaries.
Where the Herds Are
The herds occupy the Northern Serengeti, specifically around Kogatende and the Mara River, moving back and forth between Tanzania and Kenya’s Masai Mara.
What You Will Experience
- Dramatic River Crossings: Thousands of wildebeest leap off steep riverbanks into treacherous waters, battling rushing currents and waiting crocodiles.
- Unfiltered Drama: The sheer tension as herds gather on the riverbanks for hours before one brave animal takes the plunge is unforgettable.
- Peak Safari Season: Weather conditions are dry, warm, and sunny, making game drives comfortable and animal spotting easier around permanent water sources.
November to December: Returning South to the Feeding Grounds
With the arrival of the short rains in November, the dry northern grasses are replenished in the south, triggering the return journey.
Where the Herds Are
The herds move rapidly southwards from the Northern Serengeti through the Eastern Serengeti (Lobo and Namiri Plains) down toward Ndutu.
What You Will Experience
- Fast-Paced Action: The herds travel quickly during this transition phase to reach the rich feeding grounds before calving season begins again.
- Great Value: November and early December fall between the high seasons, offering lower lodge rates and fewer crowds before the holiday rush.

Essential Tips for Planning Your Migration Safari
- Book Camps Early: Mobile tented camps move with the herds and offer front-row seats to the action. Because space is limited, book 6 to 12 months in advance for peak season (July–October and February).
- Pack for the Climate: Pack layers—mornings on the Serengeti plains can be crisp, while afternoons get warm.
- Patience is Key: Wildlife movements depend on rainfall patterns, which vary slightly each year. Staying multiple nights in one area increases your chances of seeing major events like river crossings.
- Get Your Travel Documentation in Order: Before setting off on safari, ensure your entry requirements to Tanzania are squared away.
