The Great
Migration

The migration is not one event — it is a living circuit across the Serengeti, and each chapter rewards a different kind of traveller. Two million animals on the move, all year round; the only question is which chapter you want to stand inside.

Jan – Mar

Calving season

Half a million wildebeest are born on the southern plains of Ndutu — newborn herds, predators on the move and luminous green light.

Best for: Photographers · first safaris · families

Apr – Jun

Green season

The long rains empty the tracks and turn the Serengeti emerald; the herds gather and begin moving north-west towards the Grumeti River.

Best for: Great value · solitude · dramatic skies

Jul – Oct

River season

The dry season opens and the great crossings begin — first the Grumeti, then the Mara at full force. Tanzania at its most cinematic.

Best for: The classic safari · big cats · crossings

Nov – Dec

Short rains

Brief afternoon showers green the plains; the herds drift south towards Ndutu again and Zanzibar sparkles for the festive season.

Best for: Green plains · newborn gazelles · festive escapes
