The Cliffs of Moher are located at the parish of Liscannor at the south-western edge of the Burren area near Doolin, which is located in County Clare.
The cliffs rise 394 feet above the Atlantic Ocean at Hag's Head and reach their maximum height of 702 feet just north of O'Brien's Tower. The cliffs boast one of Ireland's most spectacular views.
In other words, I want to see these cliffs, in person, so badly that it makes me ache. Literally. Some day. (Soon.)
