@MartinEGJJ, did you do the trip Johannesburg to Jersey? I’m looking to do the same trip to Holland and very interested in your story. Thanks.
@JulietBravo, I think I sent you a PM a couple weeks ago. Another pilot and I are hung on a trip to Kilimanjaro (From London) because we can’t manage to get insurance for Karthoum (due to sanctions).
If you have any good contact, would you mind PMing to me?
Thanks!
Thanks everyone for your advice – I will update shortly of the new and improved route. Issues with the insurance company but all now resolved.
From pilots who flew there, though apparently not in the last 4 years. Thanks for the up to date feedback, JulietBravo.
I am not sure where Peter has his information from but Khartoum is one of the friendlier places to stop over on the eastern route. I have used it on three occasions in the last four years and with each, the avgas barrel was there on arrival, refuelling (take your own pump) was quick and we were well looked after by friendly handling agents with a good hotel nearby and efficient transport to and from.
The need for ‘douceurs’ begins south of there.
They do fairly expensive organised group events; occassionally “advertised” here 
If I was doing this I would contact the overflight agents in post #5. Ultimately just about everybody uses one of these on these routes. They have the contacts in the national CAAs and know who to “lubricate”.
A long range plane makes it all much easier (I believe the current UK-Joburg record is held by a specially fuel-tank-modded plane with a 2500nm range which had to make only one stop, in the middle of Africa) but you still need overflight permits.
On the east route, many have commented that if you have the range to cross all of Sudan, from Aswan in Egypt all the way to Kenya, that takes out the worst bit. Many stories of having to bribe pay soldiers to sleep next to the avgas drums in Sudan to make sure nobody steals them during the night
You should contact www.prepare2go.com they have quite a lot of experience with sep flying in Africa
We needed permits for south-Marroco (western sahara)
@vrh here has done multiple trips part way down the west coast, from France. It is a popular route for a group of French pilots, possibly partly because those countries are French speaking. However lots of GA has gone down to Morocco. Thre is some debate whether permits are required, for Morocco and beyond…
Nice plan!
We flew to Dakar two years ago, basically halfway down the western route. Avgas was no problem. We needed permits in Marocco and Mauretania.
