The Cliffs of Moher in Ireland, rising up to 214 meters on the Atlantic coast of County Clare, are world-famous for their dramatic beauty.

About this subject

The Cliffs of Moher are located on Ireland's west coast in County Clare, stretching approximately 14 kilometers along the Atlantic Ocean. They reach a maximum height of 214 meters at Hag's Head promontory. Since 2011, they have been part of the Burren and Cliffs of Moher UNESCO Global Geopark. The cliffs are composed mainly of sedimentary rocks from the Carboniferous period, primarily siltstone and sandstone deposited in a marine delta about 320 million years ago. Constant coastal erosion shapes these steep cliffs, creating one of the most iconic landscapes on the island.

O'Brien's Tower, built in 1835 by Sir Cornelius O'Brien, stands as a popular viewpoint atop the cliffs. Originally constructed for tourists who already visited the area, it now offers panoramic views that, on clear days, reach the Aran Islands and Galway Bay. The cliffs are also a major seabird nesting site, hosting species such as the Atlantic puffin, common guillemot, and black-legged kittiwake. An estimated 30,000 breeding pairs nest on the cliffs during spring and summer.

The site is one of Ireland's most visited tourist destinations, attracting over 1.5 million visitors annually. The cliffs have appeared in several films, including 'The Princess Bride' (1987) and 'Harry Potter and the Half-Blood Prince' (2009). For nature and photography enthusiasts, the best times to visit are at sunrise or sunset, when the light highlights the geological layers and the turbulent ocean. Entry is free, but parking at the visitor center requires a fee.
