The Great Migration River Crossings
When most people think of the Great Migration, they think of the iconic Great Migration River Crossings that take place in the Masai Mara and Serengeti from June to October which are the peak safari season in East Africa.
Actually the Great Migration is a year-long cyclical event, whereby millions of wildebeests and other plains game follow the rains from the Serengeti down through the northeast of the Ngorongoro Conservation, back up through the central and west of the Serengeti, all the way up north to the Masai Mara, and then back down again through the central and east of Serengeti.
Across the whole annual Great Migration, there is plenty of action to be found that is calving season from January to March, rutting season in April and May, and river crossing season from June to October, with the herds continuing to move south in November and December – just to start the whole cycle all over again.
Most travellers consider the river crossings to be the most exciting part of the Great Migration to witness, and a must do on the bucket list.

What Makes the Great Migration River Crossings a Bucket List Event?
The sheer volume of wildebeests, zebras and gazelles is a wonder in itself, with over 1.3 million wildebeests and 300,000 zebras and gazelles (both Grant and Thomson) taking part. This is the largest herd movement of animals in the world, so large that it can be seen from space.
The dramatic river crossings are exhilarating to watch, but patience is needed to witness this spectacle first-hand. Wildebeests can take hours or even days to cross the Mara and Sand Rivers from the Serengeti in Tanzania to the Masai Mara in Kenya. The herd eagerly awaits for one of their comrades to take the first step.
However, it is a quite a scary prospect going first, there are predators to watch out for, including crocodiles in the rivers and lions and other big cats waiting on the other side of the river to pick off the weakest of the herd. There is the muddy riverbed to navigate, with the risk of getting stuck, and some sides of the ravine may turn out to be too steep to climb up – forcing the herd back across the treacherous river to start the exercise all over again.
In the end, one brave wildebeest will take their first step or rather jump into the river, causing a cascading movement as the whole herd follows, making it a definite must-see event.
The Great Migration River Crossing: Why does it Happen?
The answer is simple, the great migration crossing happens because of food.
The wildebeests follow the rains by watching the movement of the rain clouds. They know that where there is heavy rain, the grass they eat will grow soon afterward. Instinct impels them to follow the storm clouds across the Mara and Sand Rivers.

What Other Animals Migrate?
Zebras
The zebra migration in Tanzania’s Serengeti National Park is one of the largest mammal migrations in the world. It usually takes place between June to August.
Straw-Coloured Fruit Bats
The straw-coloured fruit bat is the largest mammal migration with eight million bats traveling from the Congo to Zambia between October and December each year.
Monarch Butterflies
Unlike other migratory animals, no individual Monarch butterfly completes an entire round trip from northern America to Southern America each year. The females lay eggs for a subsequent generation during the northward migration, and up to four generations can be involved in the annual cycle.
Arctic Terns
The Arctic Terns are small, mostly white birds, with the distinguishing features of a black head and red beak. They follow the summer weather from one pole to the other. Artic to Antarctic, spending most of their time at sea. They are believed to migrate around 40,000 kilometres a year.

Following The Herd
Tips for a Rewarding River Crossing Experience
It can be hard to predict the exact movement and location of the herd, so to maximise your driver crossing sightings, planning a head is crucial.
Here are the few tips
- Plan your Great Migration River Crossings trip for the right time of the year. The wildebeest cross over the Mara River in late June through August and early September, then again when they travel back south, in late October and early November.
- Stay in the same spot for a few solid days at a time, rather than hopping from one lodge to the next.
- Talk to your guide about the best spots to look for amazing sights, they have been doing this for years and will have plenty of advice and stories to share.
