Kevin Walker lives in the Brecon Beacons area of mid Wales, and has been a professional mountain leader and hill guide for almost four decades. A self-confessed mountain addict, he ran ML training courses for several years, and has written many books including Mountain Hazards, Wild Country Camping, The Essential Hillwalkers’ Guide, and Undiscovered Wales. He runs a wide range of navigation, hill skills and mountaincraft courses, as well as offering personal tuition, 1:1 coaching, and private guiding. When not teaching or guiding, he spends most of his free time exploring, photographing and writing about the less well known parts of Wales, with occasional trips to further flung hills, most recently the Spanish Sierras de Tejeda and the Nepal Himalayas.
