Blarney Castle

Blarney Castle is an icon of Ireland and it’s always one of our favourite stops on our Ireland trips. Dating back to 1446, this beautiful castle is famed for its legendary Blarney Stone. It’s said that whoever kisses the stone will be blessed with the gift of the gab, or the gift of eloquence. But it’s not as simple as kissing the stone. You’ve got to climb the ten stories to the top, then lean backwards from the parapet walk and kiss the stone upside down for the legend to come true. Once you’ve smooched the stone, be sure to explore the gorgeous 60-acre garden around the castle.
