Great Migration calendar: So, where are the herds likely to be?

Picture roughly two million animals moving in one big loop through the Serengeti ecosystem. There's no start, no finish and no fixed date for any of it. Below is where they tend to be each month, based on where they've been in past years.

Let's be honest: nobody can promise you a river crossing. The herds follow the rain. If an operator guarantees one in a particular week, they're either guessing or selling. What we can do is put you in the right area for the month you're travelling, with enough days there for a little patience to pay off.
