The only country that perhaps surpasses even Kenya and Tanzania finds itself at the very bottom of the continent. South Africa is the most biodiverse country in Africa and has one of the two largest migrations by biomass on Earth. The "Sardine Run" off the south coast of the country is the last giant fish migration on Earth and sees individual schools of fish that can be literally cubic kilometres in size. Sharks, Dolphins, Whales and sea birds accompany the fish in their numberless thousands, making a spectacle that is hard to rival. Of course, though, it is the big land animals for which South Africa is most renowned. The black maned desert lions of the Kgalagadi Transfrontier park are world famous, Isimangaliso Park is the one place that Hippopotami, Whales, Sharks and Crocodiles frequently share waters and Hluhluwe Imfolozi is much of the reason the Rhinoceros did not become extinct in the 1980s. The Greater Kruger National Park has the largest diversity of large mammals of any reserve in the world, and is the easiest place on Earth to see “The Big 5”, particularly due to it having the largest Leopard and Rhinoceros populations in the world. Many private reserves attached to Kruger, such as the Sabi Sands, guarantee all five within a single day’s game viewing. The country's parks range from budget to some of the most luxurious hotels in the world, meaning that South Africa is a wildlife haven that not only suits every pocket, but that also offers probably the greatest game viewing in the world.
