Climbers say it has some of the hardest and longest sports climbing routes in Scotland, so little wonder they have dubbed it The Super Crag. Four of Scotland's most talented young athletes - Calum Cunningham, Emma Davidson, Rhys Langlands and Hannah Smith - travel to near Gairloch to explore this intimidating rock formation by the side of Loch Maree.

All have big ambitions: Emma and Hannah are making the transition from indoor climbing, while Calum and Rhys want to test themselves against the very best - but will they succeed on this overhanging rock face where there are no easy routes?
