The name Big 5 comes from the hunt and includes rhino, buffalo, elephant, leopard and lion. They are the most dangerous animals to hunt on foot and the animals everyone wants to see on photographic safaris.
Not everybody has the time to go on safari for several days or even weeks, so the choice of the safari destination is crucial to see the Big 5 also during a short stay in the bush. Excellent destinations are the Masai Mara in Kenya, the Okavango Delta in Botswana and the Sabi Sand (Kruger National Park) in South Africa. In these areas it can even be possible to see them within one day, which is still lucky, but possible.
The animals are still wild and do their own thing, but because of the wildlife density and that they are used to the vehicles makes it easier to spot them.
Keep that in mind when you plan a wildlife photography safari, a holiday or an incentive and you have limited time. Especially the cats are what you really want to see as a photographer. They are just stunning.
