Located on the Antrim Coast, Portrush is one of Northern Ireland's most scenic resort towns. Here, you might visit medieval Dunluce Castle (made famous as a filming location for Game of Thrones) or the UNESCO World Heritage-listed Giant’s Causeway – this volcanic formation consists of around 40,000 interlocking hexagonal basalt columns that emerge from the water, making for a truly striking scene. This afternoon, you’ll visit nearby Rathlin Island, where you’ll see some of Ireland’s largest seabird colonies. Keep an eye out for puffins, guillemots, razorbills, fulmars and kittiwakes.
