Steve Ashton lived in Snowdonia for 20 years, during which he wrote several climbing and walking books to the region. The best known of these is the highly influential and now classic Scrambles in Snowdonia, which was largely responsible for reviving interest in this esoteric sport. Carl McKeating and Rachel Crolla began their hiking careers in the Yorkshire Dales and the Lake District. They went on to walk and climb all over Europe, exploring all the major mountain ranges. In 2007, Rachel became the first woman to climb to the highest point of every country in Europe. The couple's resulting guidebook Europe's High Points was published by Cicerone in 2009.
