Hi there. Your biggest issues in going eastwards or westwards are security (flying thru war zones), overflight and landing permissions from Africa's notorious bureaucracy AND getting a reliable supply of AVgas assuming it is a normal 206 and not a turbine version.
Many routes look okay until you find out that Avgas is just not available in capital cities. And international airports for love or money. Had a friend who ferried a turbo 210 last year from Europe and even with a fair amount of money, help and pre planning he had some serious hassles to deal with enroute thru Egypt, down the Nile via East Africa etc. supposedly reliable fuel stores were not. And airports were a major test of patience and resilience. Get advice on where fuel is first and then plan your route. And help from clearance experts and companies are a must. Africa is not a place to try and smile your way thru paperwork.... Jails are not to be risked.
Start with fuel and work from there. It's not easy but possible.
