The Great Wildebeest migration was captured crossing point number 3 from North to South Serengeti. 

Once the herds arrive in the north, they do not simply head straight for the Masai Mara then head south, but they linger criss-crossing over back and forth through the Mara River – it is not a single mass movement, but more a chaotic gathering which can mean river crossings happen daily from July all the way through until late October.
