Mountain adventure programme. In a South American special, Graham Bell and Ed Leigh travel to the Exploradores Glacier in Chile and attempt to climb a 125ft glacial wall. The intrepid duo then travel north, to trek up one of the Chile's largest and most active volcanoes - the 2847m Villarica. Despite hot lava rumbling beneath the surface, the volcano is covered in snow. Ed and Graham take full advantage and ski down among the steaming crevasses. Show less
