My listings for Africa are a little patchy.
North Africa is quite well covered although the number of countries that the Foreign Office considers safe, keeps changing.
West Africa is also quite well covered now. Again, check with the Foreign & Commonwealth Office's Travel Advice while this region's politics can change quite rapidly.
Central Africa covers two destinations, popular for their gorilla-watching opportunities.
East & Southern Africa could use some work to fill in the gaps. There are some obvious countries missing. These two regions have some amazing safari camps and lodges, so I've listed some of those, as well as UK operators.
