From Dublin we headed north to the Causeway Coast, stopping to visit Malahide Castle along the way. We crossed Carrick-A-Rede Bridge, explored the Giant's Causeway, wandered around the ruins of Dunluce Castle, and spent the night in a castle of our own. We pressed on to Donegal, hiked the highest sea-cliffs in Europe at Slieve League, and continued down to Killarney. We walked around Corcomroe Abbey, visited a Beehive hut, hit the beach on the Dingle Peninsula and drove a bit of the Ring of Kerry. Then it was back to Dublin for a final day of history, culture, and city adventure.
