Horn Head

The great quartzite headland above Dunfanaghy. Sheer cliffs falling to the sea, home to one of the biggest seabird colonies in the north west, puffins, guillemots and razorbills. The loop road round the head is one of the finest short drives in the county.

Horn Head is a prominent quartzite headland formed during the late Precambrian to early Cambrian period, approximately 600 to 540 million years ago, through the metamorphism of sandstone under high pressure and temperature. Its sheer cliffs and isolated location have made it a crucial breeding ground for large colonies of seabirds, including puffins, guillemots, and razorbills, contributing to its ecological and geological significance.
