During my 3rd bicycle journey from Central Europe to Africa I crossed the west Africa for second time. The first time was in 2008 and I came back there and went further south in 2015.
Casamance region was one of my favourite one. It's in the south Senegal beneath Gambia country. Contrary to dry and desertic north Senegal, the south is a green full of life jungle. In the jungle there are plenty of mangoes trees and some cashew trees.
