Skellig Michael, or Great Skellig, is an island (the larger of the two Skellig Islands) in the Atlantic Ocean, 11.6 km west of the Iveragh Peninsula in County Kerry, Ireland. A Christian monastery was founded on the island at some point between the 6th and 8th century, and was continuously occupied until its abandonment in the late 12th century. The remains of this monastery, along with most of the island itself, were inscribed on the UNESCO World Heritage List in 1996.
Each year 13 boat licenses are granted to tour operators who each run a single trip to Skellig Michael each day during the summer season (April to October, inclusive), weather permitting. For safety reasons, because the steps up to the monastery are rock, steep, and old, climbs are not permitted during very wet or windy weather. There are also dive sites immediately around the rock.
