In early November, we would suggest basing yourself in the Kogatende and Lamai areas of the northern Serengeti to give yourself a chance of witnessing a late river crossing. In the second half of the month, it can be a good idea to split your time between the northern Serengeti and the central Seronera region of the park.
As the herds disperse, many will head down towards the centre of the park so if you are set on catching the herds, this would be a good combination of locations. This way, even if the herds haven’t quite made it down to central Serengeti, you would have most likely caught them in the north.
Aside from the migration, November is an excellent time to make the most of low rates and have an exceptional value Serengeti safari, with no other vehicles. Seronera is usually really busy in the peak months, so visiting here in November gives you a seriously spoiling more private stay in an area that in peak months is so popular (due to its phenomenal resident game).
