The Skerries are a small group of rocky islands (skerries) just off Portrush, County Antrim, on the north coast of Northern Ireland. Winkle Isle is the local name for the large Skerry island, the small Skerry being known as Castle Isle. The islands are part of an Area of Special Scientific Interest. Local boat trips from Portrush pass the Skerries en route to the Giant's Causeway.
