Bum Hill Campsite on the Caprivi Strip in Namibia. The thatched-roof hut is a shower and toilet and the ladder on the left leads up to a tree platform where we enjoyed views over the Kwando River. The noises at night were incredible... hippos grunting and plenty of insect sounds.
My favorite pic!
Late one evening near Savute in Chobe we saw a herd of impalas running back and forth in terror... we heard lions roar on one side but couldn't see what they were running from.
