My advice to anyone wishing to visit is try join into a group for travel safety. If you know a region it is different especially visiting family who will give advice. (Namibia by what I have seen is far safer than South Africa.)
Some amazing tour groups taking people throughout Southern Africa, only watch their reviews not connected. Many folk are interested to visit and love African Wildlife Photography sharing.
Living on Eastern side we travel Hluhluwe Imfolozi Game Reserve, much of iSimangaliso Wetland Park making up the ecosystem on the North/East.
Have a great day and look forward to seeing your content!
