There are a number of walks in the Comeragh Mountains of varying degrees of difficulties or if you would like to take the difficulty out of planning a walk, there are a number of different companies that offer guided mountain walks.
For those with a real interest in walking, the annual Nire Valley Walking Festival (http://www.nirevalley.com/index.shtml) may be of interest. This annual walking festival in the scenic Nire Valley offers a weekend of spectacular walking, great talking and a feast of traditional music, singing and dancing in the Nire Valley.
