In reply to Toerag:
There are strong traditional climbing ethics in Ireland. Bolting is not encouraged in the vast majority of crags, to keep the environment as natural as possible. Most of the rock is granite and has adequate possibilities for natural protection.
There is a bolted quarry near Kilkenny (Ballykeefe) but the bolting style is very different from European standards and is only there "as a last resort" in case you fall off. You might find the spacing very varied or wide apart. Its also like most quarries, a hole in the ground. Much prettier to go to Dalkey or Glendalough.
