Botswana is one of the best, but most expensive safari destinations in Africa. The older the children, the more they'll remember. I would recommend children be at least 10 years old to get the most out of a family safari in Botswana. Most safaris in Botswana will run between the months of March and November.
Recommended Family vacations in Botswana:
Family Safari in Botswana and Victoria Falls featured by Responsible Travel. This is a great 9 day trip that includes Botswana’s Okavango Delta, the Kalahari Desert (where you'll be tracking rhino with bushmen) and the Victoria Falls. Minimum age is 7 for children on this trip since most of the accommodation is in small private camps surrounded by wildlife.
