How’s your head for heights? A narrow, swinging bridge, 20 metres long and suspended 100 feet above the rocks and sea below, links mainland Northern Ireland with a tiny outcropping of volcanic rock known as Carrick-a-Rede. Many years ago it was a much more precarious crossing, when salmon fishermen would use the bridge to check their nets, before the catch here dried up. Today the bridge is one of the country’s most beloved visitor attractions - around a quarter of a million people every year make the trip across and back, though every now and again some lose their nerve and have to be rescued from the island!
