The Giant’s Causeway is probably the most famous natural site in Northern Ireland. On this stretch of coast, 50 or 60 million years ago, lava flows brutally met the sea. Layer after layer, as it cooled down, the basalt took the shape of 40,000 amazing hexagonal columns that we can still see today. It was declared a UNESCO World Heritage Site in 1986, and 300,000 curious tourists wander on its shores annually.
I would say that you had to choose ONE site to visit on the coast of Northern Ireland, it should definitely be this one. One can only be enchanted by this strange geometrical phenomenon, and it’s awesome that you can climb on the stone pillars and and explore them all you want.
The Giant’s Causeway is easy to find on the Causeway Coastal Route, about halfway between Ballintoy and Portrush. It is particularly beautiful at sunset, when all the stone pillars get enhanced by an orange glow.
