I was referring to aforementioned Southern and Eastern African nations.
But I do agree. The caveat is there are huge numbers and areas of conflict zones in Africa. The entire center of the continent is a no-go for 99% of travelers- DRC, CAR, Sudan, South Sudan, Chad, Angola, are all top-tier difficult to get into/get around. Somalia, Libya, Mali, Niger, Nigeria, Eritrea, northern Kenya, eastern Ethiopia, and Mauritania all have serious conflicts on the borders or in-country.
Frankly, this doesn't leave us with much, especially when you factor in the difficulty of little to no travel infrastructure. Mozambique, Malawi, Zambia, and Zimbabwe are good for hitchhiking, but it isn't easy. I've traveled a lot on the continent, and while it's not extremely difficult all the time, to say it "isn't that hard or dangerous" is vastly overstating the competence/self-assurance/knowledge of most travelers.
I ask- if Africa isn't hard or dangerous, then what is?
