Three years, eleven countries, 1,200 families, 14,000 kilometers of adventures while walking in the footsteps of mankind through the Cradle of Life. Alexandre and Sonia Poussin undertake to walk the length of Africa entirely on foot, from the Cape of Good Hope to the Sea of Galilee. In a three-year trek along the Great Rift Valley of East Africa, their goal is to symbolically retrace the passage of early Man, from Australopithecus to Modern Man. Without sponsors, without support team, sharing the poverty of their hosts, they speak to us on each page of the generosity and enthusiasm of these men and women who populate the African continent. Day after day, Alexandre and Sonia become a bit more African themselves. In this volume, which recounts the first seven thousand kilometers up to Mount Kilimanjaro, we are privileged to share an intimate look into the heart of Africa and her people. The adventure continues in Africa Trek II.
