The Green Island.
by sandman 31 May 2016
Known locally as The Green Island it is easily to see why.....this is the view of the island taken adjacent to the summit of Illanmaster Hill. In years gone by local farmers kept sheep on the island accessing via the ocean side. But this accent is for another day subject to the permission of Birdwatch Ireland and the hire of a boat.
