Adventurer and wildlife expert Steve Backshall climbs some of Earth's most ancient mountains, the Gran Sabana Tepui mountain range.
Steve and the mountain climbing team contend with river rapids, dangerous insects and a grueling march through dense jungle, before climbing a previously unscaled Tepui in South America. Will they be able to scale the Amaurai Tepui, or will nature and the weather have other ideas?
Steve and the team travel to the Auyan Tepui and descend into days of darkness as they explore a labyrinth of caves inside the tepui. But when they emerge they find an exhilarating view -- and have the thrill of rappelling down alongside the world's highest waterfall: Angel Falls.
