According to Google Maps, the world's longest direct one-way walk between two points is from Cape Agulhas, South Africa to Magadan, Russia. Can you name the countries you will travel through when walking between these two points via the shortest possible distance?
that's what the word 'direct' in the description means - the walk is always the shortest between those two points, and this is the longest of the shortest routes
Nice quiz, but not sure where you got L'Agulhas from, which sounds French. We call it Cape Agulhas and I've never heard anyone ever refer to it as L'Agulhas and I've lived in South Africa all my life. Awesome quiz though.
The source video (in the caveat) explains the route in the quiz. The video also had difficulties getting rid of the ferries but adapted the route so there would be no rides. It's a very interesting video and I recommend watching it if you have the time :)
Also does not touch Malawi
The route also has 2 big ferry rides, 1 across the Red Sea and another across the Black Sea. Somehow can't remove the ferries.
