Plan for the ecosystem,
not one crossing.
The Great Migration can be extraordinary, but no honest specialist can promise the exact position of the herds or a river crossing.
The herds move through the wider Serengeti ecosystem throughout the year, with timing governed by rainfall and grazing. We choose between the southern plains, western corridor and northern Serengeti according to your dates, rather than treating the Migration as a single July-to-October event.
The strongest migration safari is still a complete safari. It should allow time for resident wildlife, excellent guiding and the character of the landscape, rather than reducing the journey to a single crossing that nobody can schedule.
