The Great Migration in Tanzania and Kenya is the greatest wildlife spectacle on earth.

Grand World Tours operates in Tanzania, Kenya and Zanzibar, and this guide explains where the herds are each month, the best time to go, where to stay and 10 tips for seeing the Great Migration at its best.

What Is the Great Migration in Tanzania and Kenya?
The Great Migration is a continuous, year-round journey. The herds follow the rains and the new grass, moving through the Serengeti ecosystem in Tanzania and crossing into the Maasai Mara in Kenya. Predators such as lions, cheetahs and crocodiles follow them, and dramatic river crossings are among the most famous moments.
It is not a single event at a single place. The Great Migration in Tanzania and Kenya is a cycle, so the best location depends on the month you travel. Exact timing also shifts from year to year with the rains, which is why local guidance matters.

Where to Watch the Great Migration: Tanzania vs Kenya
Tanzania: the Serengeti
The herds spend most of the year in Tanzania. The Serengeti offers calving season in the south, the Grumeti River in the west and the Mara River crossings in the north. It is the best base for the widest range of Great Migration experiences.
Kenya: the Maasai Mara
The herds arrive in the Maasai Mara around July or August and stay until roughly October. The open grassland and river crossings make it one of the most dramatic places to watch the Great Migration in Tanzania and Kenya.
