Skiing and Ireland are not two words that usually go together. Ireland does occasionally see snow, but many winters are completely free of major snowstorms. Additionally, Ireland’s highest mountain, Carrauntoohil, only reaches 1,039 meters (~3408 feet).
The Mourne Mountains on the east coast of Ireland is dominated by the tallest mountain in Northern Ireland, Slieve Donard, which reaches 852 meters, or around 2795 feet. The mountains are a designated Area of Outstanding Natural Beauty (AONB), with the National Trust owning 1,300 acres around the site.
Like the rest of Ireland, the Mourne Mountains are not known for skiing, but that doesn’t mean people have tried. Back around Easter of 2013, a group with Rock and Ride Outdoors was able to get out on some snow and ski the mountains.
