When is the wildebeest migration season?
The wildebeest migration usually starts somewhere in June-July and goes on until November.

Can I see a crossing during the migration?
Crossings happen frequently during the migration but are difficult to predict. If you see a massing of wildebeest along the river and animals seem to be agitated, there is good chance of them crossing the river.

How can I watch a wildebeest crossing without harassing them?
You should stay inside the vehicle, do not make noise, do not approach the crossing point too close and do not interrupt/block the moving wildebeest.
