Walk: East Munster Way
This 70km walk (www.irishtrails.ie) travels through forest and open moorland, along small country roads and a lovely river towpath. It's clearly laid out with black markers bearing yellow arrows and could be managed in three days, starting at Carrick-on-Suir and finishing at Clogheen, both in County Tipperary.
The first day takes you to Clonmel following the old towpath on the Suir for significant portions of the route. At Kilsheelan Bridge you leave the river to Harney's Crossroads, then wander through Gurteen Wood and the Comeragh foothills to Sir Thomas Bridge where you rejoin the river.
On the second day, the Way first leads south into the hills and then descends to Newcastle and the river once more. The third day sees a lot of very atmospheric walking along the quiet River Tar to Clogheen.
Ordnance Survey Discovery series maps 74 and 75 cover the route.
