The principal farming activity in the uplands is sheep grazing, using mainly the Wicklow Cheviot breed. Land is also used for forestry and turf cutting. Tourism and recreation are also major activities in the uplands. Glendalough remains the most popular destination, receiving around one million visitors each year. Recreational activities in the mountains include walking, rock climbing,winter climbing, fishing and cycling. Hillwalking in the Wicklow Mountains was first popularised by J. B. Malone through a weekly column he wrote in the Evening Herald newspaper. Malone was later instrumental in the creation of the Wicklow Way, Ireland's first National Waymarked Trail, which opened in 1980 and crosses the Wicklow Mountains. The Wicklow Way has been joined by the Dublin Mountains Way and the Saint Kevin's Way pilgrim path, both of which also traverse parts of the mountains.
