The ferries run regularly throughout daylight hours, and even if there are too many vehicles at the timetabled hour they will go back and forward until everyone is across.
We spent our first afternoon on a gentle safari drive - not going too far as we couldn't find a map to purchase. Possibly could have got one at the park gate 70km back down the road!)
The wildlife viewing is very good - elephants, giraffe, plenty of antelope, hippos in the river and a small croc lying beside the ferry landing spot.
The landscape at first look is typical African savanna until you notice all the palm trees - apparently the elephants spread the palm nuts in their droppings making this landscape unique. It is spectacular as the sun starts to go down.
While we waited for the last ferry back over the river (7.00pm) we chatted to a man with a very big camera who appeared to be travelling on his own (with a guide) - he was remarkably annoyed that we had seen elephants which his guide had managed to miss. Ha ha.
