Etosha, while home to one of the world's largest salt plains, is also a spectacular base for spotting wild game in a very Serengeti-esque landscape.  The Namibian government sponsored campsites inside the park are fantastic, some of the best we have seen in Africa, boasting excellent facilities at reasonable prices, located right inside the park.  The waterholes are where I shot most of the elephants below and offer some fantastic viewing opportunities over a few beers and snacks, including some very rare rhinos.
