Cliffs rise 120 metres above the Atlantic Ocean at Hag’s Head, and, 8 kilometres to the north, they reach their maximum height of 214 metres just north of O’Brien’s Tower, a round stone tower near the midpoint of the cliffs, built-in 1835 by Sir Cornelius O’Brien, then continue at lower heights.
This nine-mile-long line of craggy cliffs along Ireland’s western coast is already a famous tourist attraction. But visiting during sunset is extra stunning, as the towering ridges make for the perfect sunset backdrop against the Atlantic.
