This answer is generalist and for tourist purposes only. South Africa has some of the best national parks and private reserves on the continent, and safari regions present significant differences. Access is easier and more convenient due to its proximity to the hub airport (Johannesburg). There are many unique and endangered species and the savannah is more closed with vegetation than in East Africa. We can say it is the best cost x benefit for safari, especially for a first experience. In addition to Kruger, Kalahari region, certain areas of Kwazulu-Natal province (in particular Hluhluwe-Imfolozi Park) and Eastern Cape are traditional and high quality safari regions. Kenya and Tanzania are classic safari destinations and often regarded as the best safari destinations in the world. Savannas are more open, there are abundant migratory phenomen and nature is exuberant. Access can be slower and complex, logistics more complicated and there are phenomenal but expensive lodges and reserves. Strongly recommended to anyone who has no budget constraints and is already initiated on safari, or wants to take a safari-focused trip. Internationally renowned parks are: Masai Mara, Samburu, Amboseli, Tarangire, Lake Manyara, Serengeti, Ngorongoro, amongst others. Botswana is also a classic safari destination, and much sought after due to the Okavango Delta, which offers amazing wooden boat (mokoro) safaris. Lodges are sophisticated, expensive and suitable for South Africa extensions. Also in Botswana are the Chobe reserves and part of the Kalahari. Namibia has a great national safari park, Etosha, which is recommended for those visiting the country on self-drive. South Luangwa, Zambia, is one of the continent's best and most remote parks, perfect for those who want an off the beaten track wildlife experience. Uganda and Rwanda are famous destinations for tracking gorillas and chimpanzees. There are also good but less structured safari regions in Swaziland, Malawi and Zimbabwe. There are wildlife reintroduction projects in the parks of Mozambique, devastated by the civil war.
