September sees the herds spread out across the northern Serengeti, where the Mara River provides the migration with its most serious obstacle. This river gushes through the northern Serengeti from Kenya’s adjacent Maasai Mara Game Reserve.

It’s common to see herds cross the Mara River north on one day, and then back south a few days later.
