The Cliffs of Moher, (Irish: Aillte an Mhothair, "Cliffs of the Ruin") are located in the parish of Liscannor at the south-western edge of The Burren area near Doolin, which is located in County Clare, Ireland.
The cliffs rise 120 m (400 ft) above the Atlantic Ocean at Hag's Head, and reach their maximum height of 214 m (702 ft) just north of O'Brien's Tower, eight kilometres away. The cliffs boast one of Ireland's most spectacular views. On a clear day the Aran Islands are visible in Galway Bay, as are the valleys and hills of Connemara.
The Cliffs of Moher were filmed as the "Cliffs of Insanity" in the 1987 film, The Princess Bride and were the location of the horcrux cave in the film Harry Potter and the Half-Blood Prince.
Geology and wildlife
The cliffs consist mainly of beds of Namurian shale and sandstone, with the oldest rocks being found at the bottom of the cliffs. One can see 300 million year old river channels cutting through the base of the cliffs.
There are many animals living on the cliffs, most of them birds: 30,000 birds of 29 species. The most interesting are the famous Atlantic Puffins, which live in large colonies at isolated parts of the cliffs and on the small Goat Island. Also present are hawks, gulls, guillemots, Common Shag|shags ravens and choughs.
From Galway, there is a bus service to the cliffs.
The cliffs make for a nice bike ride from Lahinch and other nearby towns.
1 Shannon Airport (SNN IATA) is the largest airport serving the West of Ireland. The most direct bus there can be taken to Ennis and then to the Cliffs of Moher. It is also served by an hourly bus to Galway, and car rentals are also available.
The Cliffs of Moher are amongst the most impressive places to see in Ireland, and are widely considered to be one of Ireland's top tourist attractions, with almost one million visitors in 2006.
The site has been developed by Clare County Council and Shannon Heritage to allow visitors experience the spectacular natural impression of the Cliffs, without the distraction of imposing man-made amenities or features.
In keeping with this carefully-balanced approach, the "Cliffs of Moher Visitor Experience" is built into a hillside approaching the Cliffs, blending naturally with the surrounding countryside.
Opened in February 2007 having been built over 17 years, the €32 million facility features interactive media exploring topics such as the origin of the Cliffs in local and global geological contexts and the bird and fish life in the area. €6/adult, €4/student/disabled/seniors, free/children under 16.
An IMAX-type multimedia show allows visitors to experience a bird's eye view from the cliffs, as well as seeing the inside of underwater caves at the foot of the cliffs.
