It is a pathway of sorts, made out of about 40 000 basalt columns. An ancient volcanic explosion formed this amazing place 60 million years ago. The columns themselves are mostly hexagonal and about 12 meters tall. Today it is one of the most visited places in Ireland and has its very own mythology and folklore.
