Book excerpt: Hillwalking is one of Ireland's most popular leisure activities today. Rock climbing has developed to a level of technical excellence with crags in almost every county and numerous indoor climbing walls. Irish mountaineers have completed winter ascents in the Alps, scaled the highest Himalayan peaks and other previously unclimbed giants, and explored hitherto unknown valleys. Paddy O'Leary recounts the history of hillwalking and mountaineering in Ireland: from the early activists – some were involved in gunrunning, others died at Gallipoli – until the turn of the millennium, when mountaineering in Ireland was no longer the preserve of the middle class. This history recounts the adventures, dangers, successes and failures which make this multifaceted activity such a fascinating one, and mirrors the spirit of all who love these places. * Also available: The Longest Road by Sean Rothery
