Although Naturism in Ireland is hard to come by, this group is trying to make it legal and accepted in the country. check them out! They are affiliated with the INF too.
There are links to beaches (unofficial of course!), clubs and places to go. There is also a survey and polls which I urge you to check out and participate if you can.
