Often considered the most beautiful lighthouse in the World, Fanad Llighthouse in County Donegal is perched on what feels like the edge of the World. It is a truly breathtaking site and an ideal spot for a long bracing walk. What better way to protect you from the elements than with these fabulous Donegal wool walking socks from Avoca Woolen mills, the oldest working Mill in Ireland, based in County Wicklo since 1723.
