Also, for those interested in something a bit more up to date, there's At the Edge of Ireland, Seasons on the Beara Peninsula by David Yeadon, published 2009. It will cost you $9.78 (USD). Here's a bit about it:
On the Beara Peninsula of southwest Ireland, the Yeadons discovered their own "little lost world," an enticing Brigadoon of soaring mountain ranges and spectacular coastal scenery, far removed from the touristic hullabaloo of Dublin, Killarney, and the Ring of Kerry. Here is the fabled "Old Ireland," alive and well with music seisuins, hooley dances, and seanachai storytellers—a haven for searchers, healers, artists, and poets hardy enough to have braved the same narrow and winding mountain roads that keep the package-tour coaches out.
Bursting with color and life, At the Edge of Ireland is an intrepid wanderer's celebration of a magical, unspoiled, and unforgettable Éire.You can get all of these on your web enabled computer, pad, smartphone, e-reader, etc... Just the thing to read on those long flights when you don't want to look at the overpriced things in the airline's magazine.
