I've been staying at Lamai Serengeti for the last week; we are still seeing some herds crossing the Mara river north to south (these pictures taken 2 days ago) but I think these are amongst the last of the herds now and they will start heading south. The rain up here has been quite patchy this last week, and it appears to be raining a lot further south. Still, my guests were very happy to see this particular crossing.
Thanks to Rem for the update and images
