Jim Ryan is a chartered civil engineer with a passion for the outdoors, who has had several successful guidebooks and one work of fiction published. He has a particular interest in geology and a love of mountains. Aconcagua and its region made a significant impression on him on his first journey there as part of an expedition to one of the world's great mountains in 1999. He returned on two further expeditions. Jim has been climbing the mountains of Nerja for over 15 years. His guide to these mountains is his way of repaying Nerja and Andalucía for many years of pleasure; his share of the proceeds go to Cudeca, a cancer hospice charity in the province of Malaga.
