Skip Blarney. It's on Rick Steves top tourist traps of Europe for good cause. The grounds are nice but there are hundreds of prettier better sights to see. Seriously a waste of time. Here's Ricks comments.....
Blarney Stone (Ireland): Busloads line up to kiss a stone on the top of a castle rampart and get “the gift of gab.” The best thing about this lame sight is watching a cranky man lower lemming-like tourists over the edge, belly up and head back, to kiss the stone while an automated camera snaps a photo — which will be available for purchase back at the parking lot. After a day of tour groups mindlessly climbing up here to perform this ritual, the stone is slathered with spit and lipstick."
Enjoy something else that actually connects to real Irish history.
