This 206km waymarked walk (see www.irishtrails.ie) forms a loop around the Beara Peninsula and takes around nine days. The peninsula is relatively unused to mass tourism and makes a pleasant contrast to the Ring of Kerry to the north.
The Beara Way mostly follows old roads and tracks and rarely rises above 340m. There's no official start or finish point, and the route can be walked in either direction. It could easily be reduced to seven days by skipping Bere and Dursey Islands and, if you start at Castletownbere, you could reach Kenmare in five days or less.
There's an online guide to the walk (and the peninsula itself) at Beara Tourism (www.bearatourism.com).
