Known as the Emerald Isle, Ireland is characterized by its rolling green hills and lush countryside, dotted with friendly country towns, dry stone walls and crumbling castles. Cruise to Ireland to visit the Cliffs of Moher, a UNESCO Global Geopark, about a two-hour drive from Cork, to see where the bright blue waters meet towering sea cliffs, or head to Cork’s Blarney Castle to be granted the gift of gab by kissing the famous Blarney Stone. To step back in time, see Dublin’s Malahide Castle, dating back to the 12th century. Don’t leave without enjoying a pint of Guinness and listening to traditional Irish music at a local pub on Dublin’s Fleet Street or Grafton Street.
