Fair Head is regarded as one of Ireland's best outdoor rock climbing areas, along with the limestone sea-cliff of Ailladie in County Clare. It does not attract a high volume of rock climbers due to its relatively remote location, and the physical strength and unfamiliar climbing techniques it requires of climbers. Its cliffs stretch over 5 km around the headland, rising to a maximum height of over 100m. They are not sea-cliffs but have been described as a mountain crag by the sea, since they tower above an extensive boulder field and their isolation and size gives climbing there a big-wall mountaineering feel.
