Cliffs of Moher
The Cliffs of Moher , (Aillte an Mhothair in Irish, or 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 kilometers 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 movie, The Princess Bride.
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.
By sightseeing tour from Dublin
Several Dublin based tour operators such as Kennedy & Carr Travel  offer daily tours from Dublin city to the Cliffs, often including other areas of interest along the way such as Galway Bay, Bunratty Castle, Dunguire Castle, the limestone "Burren" area, Poulnabrone Dolmen and Doolin fishing village with its charming traditional pubs "FitzPatrick's and "O'Connor's". Typically tours depart around 07:00-08:00 in the morning and return at approximately 20:00. Tickets generally cost around €45. For many travellers such tours can provide the independence they want with the structure and local insight that makes for a relaxing tour. Such operators also offer private hire services upon request both from Dublin and from Galway.
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, drawing 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.
Officially opened in February 2007 having been meticulously planned and built over a 17 year period, the €32M facility features an informative array of interactive media, exploring topics such as the origin of the Cliffs in local and global geological contexts, the bird and fish life in the area, and many more. €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.
The cliffs are not blocked off by a fence or guard, so you should take care to not get too close to the edge of the cliffs as the ground under foot can loosen.
