Went to the West coast of Ireland about 5 years ago. Flew from Prestwick to Shannon, bought a cup of coffee in the plane and we were landing before I had finished it!
Stayed in B&B the first night in Bunratty and went to "Durty Nellie's Pub" and then the castle and folk museum. It was great! (Wasn't too impressed with Durty Nellie's though). We drove round the Ring of Kerry and went to Dingle (An Dingean) to see "Fungi" the dolphin. Went to the Cliffs of Moher, couldn't see them for mist and rain!
Went to "The Burren" and Aillwee cave, got soaked in there too with the water dripping through the limestone but it was great! Went to Cong (Quiet Man country) and the "Rising of the Waters". Lisdoonvarna and the "Matchmaker's" festival.
We actually hired a cottage for the week near Scariff on Lough Dearg in County Clare, I had to get the landlady to show me how to light the "turf" fire...the shame!
Overall, I would say Ireland is fantastic...except it's like Scotland and pisses down all the time!
