Steve Backshall's Extreme Mountain Challenge (R) (T)

Part one of two. The naturalist leads a team of rock climbers across Venezuela's tepuis - sheer-sided mountains surrounded by jungle. In the first episode, he attempts an ascent of a rockface that has never been climbed previously to discover what kind of animals live at the summit. However, to get there he will have to brave wildlife, rapids and a run-in with a rickety biplane.
