Apart from Club Aquarius, a naturist club based in the province of Leinster, there appear to be no grounded naturist clubs. Club Aquarius itself seems quite guarded in terms of its location. There are however organised nudist events. up and down the country such as nudist swims and meetings, and there is information available from official nudist associations such as The Irish Naturist association.
There are some beautiful beaches in Ireland, but currently only one beach in Ireland has been designated a nudist beach. Hawk Cliff in Dalkey in County Dublin is the first official nudist beach in Ireland. It opened in April 2018 thanks to a massive campaign by the Irish Naturist Association.
