Hi. Great to hear all the positivity from friends from the US! As a citicizen of SA I would venture to say with 99.9% certainty that visitors to SA will be safe! Especially visitors who are being guided! There are tons of unguided foreigners wondering SA! Go any of the more well know tourist attractions and you'll see every people from all over the world in self drive hire cars! How often do you hear about them getting mugged/held up/murdered? Yes we have crime, but if you are sensible, and minimise your exposure, you will be fine, just the same as you wouldn't foolishly expose yourself to unneccesary risks in your home country! Please, come and experience the wonder and beauty of our country!
