Dublin is one of the most famous Irish cities, and rightly so! Form traditional music at the Cobblestone to the classic Guinness Brewery at St. James' Gate there's a wealth of things to do. Find out some more of them here by terry
Derry, Northern Ireland, is one of my favorite places to visit. I would move there in a heartbeat! The city is beautiful despite years of conflict and loss throughout its long history. Large walls twist and turn through the city, dividing it into separate neighborhoods with specific cultures. Walking the wall could take a long time (there are over 100 distinct sites of note along it), so I would highly suggest an overnight stay or hiring a private tour guide.
Bunratty Castle in Ireland. Tour the Castle grounds and the medieval Castle town, finish your tour with a medieval banquet in the Castle itself! A must do when visiting Ireland :) I love the entire experience!
