The limestone cliffs at White Rocks loom high above one of the area’s most spectacular beaches and stand guard to a network of coastal caves and arches carved through the centuries. Relax and take in the view while the kids run along the beach and build endless sandcastles. Take a boat tour from Portrush and explore the caves, which are accessible only from the sea, and view a variety of seabirds. Hike to the Dunluce Castle, considered to be Ireland’s most romantic.
