Having spent Monday night at Hillsborough Castle, the Royal couple made their first ever visit to the world famous Giant’s Causeway on Tuesday morning.
They also took a trip on one of the world’s most picturesque railway journeys, to Bellarena station, to officially open the new platform.
Tourism NI chairman Terence Brannigan commented: “We are delighted that The Queen and The Duke of Edinburgh are visiting Northern Ireland as part of Her Majesty’s 90th birthday celebrations.
“Northern Ireland is brimming with exciting tourism destinations so it is a privilege that Her Majesty will experience some of our most renowned beauty spots such as the Giant’s Causeway, the village of Bushmills and the breath-taking scenery on the train journey between Coleraine and Bellarena Railway station.
“We would encourage our visitors to follow in The Queen’s footsteps and take the opportunity to experience some of these wonderful places”.
