Hi Hugh. We went to Ireland for the first time, for two weeks in September. I posted on here for advice - if you go to the topic entitled "Ireland" on 5 September you will see the very useful response I got. The web site - www.camping-ireland.ie - will give you all the sites, and there are a few in the CC guide.
We stayed at :
River Valley, County Wicklow, *
Blarney Caravan and Camping Park, Cork,
Flemings White Bridge, Killarney, *
Glen of Aherlow, Tipperary, * and
Camac Valley, Dublin.
Those marked * are in the CC guide.
All were excellent sites. The scenery on the South coast - Ring of Kerry, and Dingle Peninsular - was superb (don't know why we haven't done it before). However, some of the roads can be narrow and bumpy for caravans so I would advise sticking to main roads when towing, where possible.
Hope this is helpful
Keith
