The Giant’s Causeway is the most visited tourist attraction in Ireland. Only here do the remarkable columnar-jointed volcanic lavas, seen high in the cliffs further east, come down to sea level. The site has been visited by millions of people, and thousands of geologists, over the last two centuries. Surely there is nothing new to be discovered there? But a theory that has held sway for more than 80 years has now been debunked, based on evidence that was hiding in plain sight all along.
Meet natural sciences curator Mike Simms in the car park for a guided tour of the shore.
Some surfaces we will be walking over are uneven, boulder strewn and can be slippery. Stout footwear essential.
