There are 56 sovereign countries on the continent of Africa. Tanzania has a different model than most of the southern African countries where you fly into private game reserves. In Tanzania you game drive between locations especially in the Serengeti National Park. In general, there are greater volumes of wildlife in Tanzania than in other countries. There is no other African country that has a wildebeest and zebra herd numbering 2 million individuals. Tanzania also does not allow any private reserves inside any national parks so you remain with the same vehicle and safari guide throughout your safari.
