Coastlines, castles, and hospitality abound on the Emerald Isle. Pucker up at the Blarney Stone; sip a stout in a thatched-roof pub, or after a tour of the Guinness Storehouse in Dublin; or feel the icy blast of the Atlantic at the Cliffs of Moher. Indisputable highlights include the UNESCO-listed Giant's Causeway, with its mysterious rows of hexagonal columns; the culture-rich cities of Galway and Cork; and the natural wonders contained by the Ring of Kerry. Roughly 300 miles long, the island can easily be explored end to end, with live music, ancient ruins, and traditional watering holes never too far away from any stop.
