However, when filming was complete, the presenter could "hardly credit" all that he had accomplished. During the course of the series, Rhys Jones had built a snow hole, climbed Ben Hope in blizzard conditions (guided by series consultant and mountaineer Cameron McNeish), and scaled (among others) Napes Needle and Catbells in the Lake District, Suilven, Scafell, Tryfan, Cairn Gorm, and Schiehallion. He had ascended a total of fifteen British mountains, some of them multiple times for the benefit of the cameras. His intention was to discover how the upland ranges that cover a third of Great Britain shaped its inhabitants, their culture and their history. Rhys Jones was assisted by experts on each particular region, together with mountain safety advisors, who were on hand throughout the making of the series.
