The cliff stretch for 8 kilometers and rise 120 meters above the Atlantic Ocean at Hag's Head , and reach their maximum height of 214 meters just north of O'Brien's Tower. On a clear day the Aran Islands are visible in Galway Bay, as are the valleys and hills of Connemara.

Midpoint of the cliffs is the O'Brien's Tower, a round stone tower. It was built by Sir Cornelius O'Brien, a descendant of Ireland's High King Brian Boru, in order to impress female visitors. From atop that watchtower, one can view the Aran Islands and Galway Bay, the Maum Turk Mountains and the Twelve Pins to the north in Connemara, and Loop Head to the south.
