From Valentia Island, we drove to Killarney to return our rental car, then took the train to Dublin. We couldn't pass up the chance to spend a few days there, though, before hopping on a flight back to the states! It's a fascinating city, and we only got a glimpse, but we both agree it'd be fun to revisit sometime in the future. The name Dublin was originally Dubh Linn (duv lin), meaning "black pool", from a large tidal pool that existed near the site of the original castle.
