13. Cliffs of Moher, Ireland
The Cliffs of Moher are located at the southwestern edge of the Burren region in County Clare, Ireland. They rise 120 metres (390 ft) above the Atlantic Ocean at Hag’s Head, and, eight kilometres to the north, reach their maximum height of 214 metres (702 ft) just north of O’Brien’s Tower, which is a round stone tower near the midpoint of the cliffs that was built in 1835 by Sir Cornelius O’Brien. From the cliffs, and from atop the tower, visitors can see the Aran Islands in Galway Bay, the Maumturks and Twelve Pins mountain ranges to the north in County Galway, and Loop Head to the south. The cliffs rank amongst the most visited tourist sites in Ireland and receive approximately one million visitors a year. The closest settlements are Liscannor (6 km south) and Doolin (7 km north).
