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 rhinos clashed horns repeatedly for several minutes in order to see who took precedence. Meanwhile a whole herd of elephants strolled in without making a sound.
Then it was the lions turn, followed by a female rhino and her young calf who drank little more than five metres from where we sat. No-one wanted to go to dinner. This was completely engrossing viewing.
