During the tail end of the rainy season, Angus Deayton and Mariella Frostrup drive up Madagascar's eastern coast.

Hugh Bonneville and Jessica Hynes take a terrifying road trip through the former Russian state of Georgia.

Funny men Phill Jupitus and Marcus Brigstocke head to Bolivia for a high-altitude road trip that promises adrenalin, hilarity and drop-dead beautiful scenery. Already good friends, the terrified duo first have to survive Bolivia's infamous Road of Death only to find themselves deep in notorious bandit country. Disorientation takes them by surprise as they have to navigate the stunning Salar de Uyuni, a salt lake so vast that Buzz Aldrin could see it from space. Their goal is to reach the ancient mountain city of Potosi whose silver once financed the great Spanish empire but at almost 5000 meters above sea level this proves to be a heart stopping finale.
