Hello Ellen, You really must include a side trip to Newgrange. It isn't far from Dublin. You will have to look it all up I just remember that we stopped there on our way from Belfast to Dublin. It is amazing. Here is a link: http://www.knowth.com/newgrange.htm If you check on some of the maps you will find a lot of Megalithic Tombs and stones in Co. Cavan. The place is dotted with them. None will be like Newgrange. It is something apart. I don't know if you are interested in this kind of thing. I just thought I would mention it. Have fun Pauline
