Cliffs of Moher

Standing on the plateau at the Cliffs of Moher for the first time, it takes a moment for the scale of the place to register. The cliffs run for 14 kilometres along the Atlantic coast of County Clare, their near-vertical faces dropping 200 metres into the sea in bands of grey sandstone and shale that shift through dozens of shades depending on the light and the state of the tide. On a clear day the view south reaches to the Aran Islands, their flat tops barely distinguishable from the sea itself, and beyond them to the mountains of Connemara on the mainland, pale and slightly veiled by sea-haze. To the north the cliffs fade into the distance until they become a grey wall on the horizon. The sound below is constant: waves against rock, gulls wheeling on the updraught, and in season the dense, noisy colonies of puffins, razorbills and gulls that nest in every available ledge. The Cliffs are geologically young by comparison with much of Ireland's landscape, formed in the last 300 million years, and the rock layers record that history in compressed sandstones, mudstones and fossils that tell us something about the seas that once covered this land.

O'Brien's Tower, a stone observation post built in 1835 by the local landowner Sir John O'Brien to give visitors a vantage point, stands near the midpoint of the cliffs and serves as a useful reference for scale that the cliffs themselves make notoriously hard to judge. From the tower a path runs north and south along the cliff edge, and it is possible to walk to the northern end near Hag's Head in roughly two hours, though the path is narrow and the drop is serious, and wet weather makes it genuinely hazardous. The visitor experience has been carefully managed since the 1970s: a large visitor centre built into the hillside contains exhibitions on the geology, wildlife and cultural history of the cliffs, and the car park and path network have been routed to keep foot traffic away from the most sensitive nesting areas. The cliffs fall within the Burren and Cliffs of Moher Geopark, a UNESCO Global Geopark designation that recognises the international geological significance of the area.

The seabird colonies that occupy the lower cliff faces in summer are one of the most vivid arguments for visiting outside the peak afternoon hours. The ledges support one of the densest nesting aggregations of seabirds in Ireland or Britain: northern gannets, kittiwakes, razorbills, guillemots and Atlantic puffins all crowd the available space, and the air above the colonies in May and June is alive with the sound of wings and alarm calls. The puffins, which are the most immediately appealing to visitors because of their appearance and comic在地上 movement, arrive in April and are mostly gone by late July, leaving the other species to continue the season. Sunset at the Cliffs is an event that draws crowds in all seasons, but particularly in summer when the long evening light turns the limestone bands amber and then deep orange, and the shadows of the cliff faces draw long dark lines across the plateau that shift perceptibly minute by minute as the sun drops. The Cliffs are genuinely crowded in July and August, and the experience is noticeably different in late April or early October when the light is often at least as beautiful and the paths are quiet.

The Cliffs are among the highest sea cliffs in Europe and present one of the most dramatic coastlines on the continent.

The seabird colonies in summer are among the most accessible and spectacular in Britain and Ireland.

The UNESCO Global Geopark designation reflects geological layers that record 300 million years of Earth's history.
