The smaller island is Little Skellig. It is closed to the public and holds Ireland’s largest and the world’s second-largest Northern Gannet colony, with almost 30,000 pairs. It is about 1.5 km east-northeast of Great Skellig.
The larger island is Great Skellig, also known as Skellig Michael, and has two peaks rising to over 230 m above sea level. With a sixth-century Christian monastery perched at 160 m above sea level on a ledge close to the top of the lower peak.
For those people who would like to experience the history and culture of the Skellig islands in an indoor environment then the Skellig Experience is for you. In the centre’s auditorium, you can experience an audio-visual presentation in which you can follow in the footsteps of the Skellig monks. Learn about the monks who lived on these desolate rocks, the seabirds, the nearby lighthouses and the marine life of the Skelligs. There is also some content on the lighthouse and other artefacts relating to Valentia Island housed in the centre.
