The Great Migration is a never ending loop. The herds calve on the southern Serengeti plains early in the year, move north through the Serengeti as the grass runs out, and cross the Mara River into Kenya in the dry season, before heading south again with the short rains.
For most of the year the migration is in Tanzania. Kenya gets the most dramatic chapter: the river crossings, when thousands of wildebeest plunge into the crocodile filled Mara River.

- In Kenya

Peak migration in the Masai Mara, with river crossings most days somewhere along the Mara River.
Where the herds are: Northern Serengeti and Masai Mara
River crossings: what to expect
- They can't be predicted: Herds may gather on a bank for hours or days, then cross in minutes, or turn back. Guides share news by radio, but patience is part of it.
- Allow time: Three or four nights in the Mara, with full day game drives, gives you a good chance of seeing a crossing in August or September.
- Crowds: Crossing points in the main reserve can draw many vehicles. Rangers keep vehicles back from the river so the animals can cross.
- Not just wildebeest: The herds draw lions, leopards, cheetahs and hyenas, so big cat sightings are excellent in migration season.
Where to stay for the migration
| Area | Good for | Keep in mind |
|---|---|---|
| Main reserve, near the Mara River | The shortest drive to the crossing points | The busiest area in August and September |
| Mara Triangle | Crossings with fewer vehicles and strict rules | In the western reserve, reached via the Oloololo Gate or by air |
| Northern conservancies | Quiet game drives, walking and night drives | About 30 to 60 minutes' drive to the river crossings |
See our Masai Mara guide for how the reserve and conservancies compare.
Seeing the migration outside July to October
From December to March the herds are on the southern Serengeti plains in Tanzania, where calving in February draws big predator action. Many tours combine Kenya and Tanzania; see Kenya or Tanzania for a safari.

Frequently asked questions
What month is best to see the Great Migration in Kenya?
August and September are usually best, with the herds in the Masai Mara and river crossings most likely. July and October can also be very good.
Is the migration in Kenya or Tanzania?
Both. The herds spend most of the year in Tanzania's Serengeti and usually spend July to October in Kenya's Masai Mara.
How many days do I need to see a river crossing?
Allow at least three nights in the Masai Mara in August or September. Crossings happen on their own schedule, so more time means better odds.
