Steve Backshall’s Extreme Mountain Challenge (BBC 2/HD | 8:00pm to 9:00pm | Sunday 13th March 2016)

Adventurer Steve Backshall embarks on one of the most dramatic and dangerous expeditions ever filmed by a BBC crew. The second episode picks up where episode one left off with Steve and the climbing team halfway up the unclimbed, sheer-sided face of a remote tepui, about to make one last desperate attempt to reach the summit. It is then on to the second stage of the expedition. Joining up with a team of elite Italian cavers, Steve ventures deep within a tepui – inside a newly discovered cave. Within this dark underworld, the team encounter strange creatures, ancient mysteries and the raw geological forces that give the tepuis their unique shape. But nothing can prepare them for an attempt to forge a path into unexplored areas of the cave – a dangerous mission of intense claustrophobia and nerve-shredding tension. To end the adventure, Steve reunites with the climbing team to abseil alongside the Angel Falls – the highest waterfall on earth.
