South Africa, Swaziland, Namibia, Botswana, Zimbabwe, Zambia, Mozambique, Madagascar, Malawi, Tanzania, Kenya, and Ethiopia are safe to visit. Adhere to the basic principles of navigating any large city anywhere in the world: do not carry valuables in plain sight, keep cameras hidden and do not walk alone at night. Make use of hotel safety deposit boxes.
Travellers with tour operators are the least at risk and self-drive clients are advised to plan in advance what routes they wish to travel, and to get all of their destination information ahead of time. If travelling by car, make sure the doors are locked at all times and that no bags or purses left on passenger seats – and in the bush the only danger you will encounter are wild animals.
African culture is gracious and hospitable and will take care of you to its full capability.
