Renowned filmmaker Paul Diffley has brought his technical skills to the caving world, with his new film The Ario Dream. The film profiles the exploration of the deep caves of Ario in the Picos de Europa mountains, Northern Spain. The film follows the latest 2016/17 expeditions as they try to make the last few connections that could result in the deepest cave system in Europe. This is a gripping account of ‘expedition-style’ cave exploration involving underground camps and complex logistics, and where the penalties for unforeseen emergencies or problems are severe. At the apex of the operation are the cave divers, pushing into the unknown in deep sumps where rescue is not an option. The tension, as each diver disappears into the blackness, is genuine… People’s Choice Award – Kendal Mountain Film Festival 2017.
