Cliffs of Moher

The Cliffs of Moher are tall sea cliffs found at the southwestern edge of the Burren region in County Clare, Ireland. These cliffs stretch for about 14 kilometres, or 9 miles. At their southern end, called Hag's Head, they rise 120 metres, or 390 feet, above the Atlantic Ocean. Further north, they reach their highest point of 214 metres, or 702 feet, near a round stone tower called O'Brien's Tower. This tower was built in 1835 by Sir Cornelius O'Brien.

Nearby villages include Liscannor, about 6 kilometres to the south, and Doolin, roughly 7 kilometres to the north. From the cliffs or the tower, visitors can see beautiful views of the Aran Islands in Galway Bay, as well as mountain ranges like the Maumturks and Twelve Pins, and far-off places such as Loop Head.

The Cliffs of Moher are one of Ireland's most popular tourist spots. Each year, around 1.5 million people come to see these amazing cliffs and enjoy the spectacular scenery.

Name

The Cliffs of Moher get their name from an old fort called Mothar or Moher. This fort was once located at Hag's Head, the southernmost point of the cliffs. It was still standing in 1780 but was torn down in 1808. The stones from the fort were used to build a lookout tower, which was meant to warn of any possible attacks during the Napoleonic wars.

Tourism

The Cliffs of Moher are one of Ireland's most popular places for visitors to see. In 2006, they were the top attraction with nearly one million people visiting the official visitor centre. With extra visitors to other spots, about 1.5 million people come each year. In 2022, around 1.1 million people visited, and many came from the U.S. Since 2011, the cliffs have been part of the Burren and Cliffs of Moher Geopark, a special group of natural places in Europe that belong to the European Geoparks Network and are recognised by UNESCO. The cliffs are also a special stop on the Wild Atlantic Way tourist trail.

Most visitors go to the official visitor centre. In the 1990s, Clare County Council planned to build a centre that lets people enjoy the cliffs without adding too many buildings. The modern centre was built into a hillside and opened in February 2007 after 17 years of work. It uses green energy like solar panels and recycling water. The centre has displays about the cliffs' rocks, history, plants, and animals. There is a big screen showing views from the cliffs and videos from caves below. There are also cafés and shops.

The visitor centre had over 1.4 million visitors in 2016 and grew to about 1.6 million in 2018. To manage the crowds, visitors are encouraged to come at quieter times, and discounts are offered for off-peak visits. The centre stays open later in summer to help with busy times.

The official walk along the cliffs is 14 kilometres long, from Hag's Head to Doolin, and passes the Visitor Centre and O'Brien's Tower. There are two paths near the centre; the official path is safer, while another path is closer to the edge. In July 2016, a walking path outside the official area was closed because of falling rocks. People were asked to stay on the safer path. Sadly, some visitors still got hurt by going off the path, so in February 2025, the coastal walking trail was closed for safety. It was still closed as of September 2025.

Tourists can also see the cliffs from the sea by ferry or from the air in small planes from Connemara Airport.

Geology and wildlife

The Cliffs of Moher are made from layers of old rock, including shale and sandstone. These rocks formed between 313 and 326 million years ago when a river carried sand, silt, and clay into an ancient sea. Over time, these materials settled and turned into stone, creating the cliffs we see today. You can find marks in the rocks that were made by ancient sea creatures, like worm tracks and tiny burrows.

Today, the ocean continues to shape the cliffs. Waves wear away at the base, sometimes causing parts of the cliff to collapse. This process creates interesting landforms like sea caves, tall columns of rock called sea stacks, and leftover pieces called sea stumps. One famous sea stack, called Branaunmore, stands 67 metres tall below O'Brien's Tower. There are also beautiful sea arches to see, especially at Hag's Head.

The cliffs are also a home for many birds, with around 30,000 pairs visiting during peak season. You might spot Atlantic puffins and razorbills nesting there. The area is also a spot to see sea animals like grey seals, porpoises, dolphins, minke whales, basking sharks, and sometimes even sunfish. Land animals such as feral goats, foxes, badgers, Irish hares, and farm cattle can also be found nearby.

Popular culture

The Cliffs of Moher have been featured in many movies and music. Films such as The Princess Bride used the cliffs as a filming spot. They also appeared in Harry Potter and the Half-Blood Prince where characters search for an important item in a sea cave. Other movies include Leap Year and Irish Wish.

Music videos for songs like Maroon 5’s “Runaway” and Westlife’s “My Love” have also been filmed there. There is even a traditional Irish tune named after the cliffs.

Transport

The Cliffs of Moher can be reached by bus through Bus Éireann route 350. This bus connects the cliffs to places like Ennis, Ennistymon, Doolin, Lisdoonvarna, Kinvara, and Galway. The bus runs several times a day in both directions. There is also a shuttle bus that operates from Doolin to the cliffs.
