Some people with limited amounts of time or who would prefer not to make their own arrangements opt for the "overlander" experience. Many operators run tours in large trucks that are comfortable and equipped with facilities for around 8-30 persons. They're generally run on a pretty tight schedule and cover a lot of distance, such as "Nairobi to Johannesburg in six weeks". These tours are run throughout the whole continent but East and Southern Africa are by far the most popular destinations. Accommodation is mostly camping with tents provided. Most meals are arranged and many are prepared by those on the trip (cooking duties rotated throughout the trip), and free time (like everything else) is scheduled. However, there is plenty of time to participate in the adventure activities that certain areas of Africa are famous for such as Victoria Falls, Swakopmund, Zanzibar, and Serengeti National Park. Some people really enjoy these tours, especially when they do not have enough time to organize all travel arrangements themselves. Others loathe the very thought of traveling in a group and think that they keep you way out of touch with the "real" Africa. Whatever the case, they're a very different way to travel through Africa. The people that go on these tours tend to be young at heart and slightly adventurous; these tours are not luxury trips.
