I recommend visiting - Etosha National Park, Namibia
Sitting at a waterhole at Okaukuejo Camp in the early evening as the animals took it in turns to come and drink. At one point two rhino clashed horns repeatedly for several minutes in order to see who took precedence. Meanwhile a whole herd of elephant strolled in without making a sound. Then it was the lion's turn, followed by a female rhino and her young calf who drank little more than 15 feet from where we sat. No-one wanted to go to dinner. This was completely engrossing viewing.
