An extension of the Appalachian Trail will include a stretch of Ireland from the Slieve League cliffs in Donegal along the Bluestacks Way, Ulster Way and ending in the Causeway Coast Way in County Antrim.
In North America, the Appalachian Trail stretches from Maine to Newfoundland, and although Newfoundland and Ireland are separated by an ocean now, they were once fused together to form one supercontinent which included Europe, Greenland, North America and parts of North Africa. Source: Irish Times
