Charting new territory, the team sets off down the Great! Gariep with the help of a local Nama farmer and friend of Oompie’s, called Oom Koos. He leads them down the river in rafts and canoes, but before they can go on the water, the explorers first have to go over the safety guidelines for running the rapids. (Prime Video)
