Here lies the medieval Dunluce Castle ruins. Perched picturesquely at the edge of a rocky outcropping high above the sea, the castle is dramatically surrounded by terrifyingly steep drops, which the early Christians and Vikings would have considered a very important security feature. The castle and surrounding areas have been frequently used for the filming of “Game of Thrones”. Another attraction reached from Portrush is the Giant’s Causeway -40,000 hexagonal basalt columns that descend in a kind of pathway to the sea. Formed over 50 million years ago, visitors have marvelled at its majesty and mystery for centuries, and UNESCO has recognised this site with World Heritage status.
