Brash Atlantic waves crash against the bizarre hexagonal basalt columns of the Giant's Causeway, formed either by a volcanic eruption 60 million years ago or the brawny actions of legendary giant Finn McCool.

Whichever story you believe, these amazing geological formations are Northern Ireland's definitive tourism icon and only UNESCO World Heritage Site. This natural phenomenon continues to be shaped by time and tide, so beware of slippery surfaces, sudden waves and falling rocks.

Interactive exhibitions depict both fact and myth at the state-of-the-art Visitor Centre, where you can also shop for unique and locally-crafted souvenirs and grab some food at the cafe. Find out more and get online ticket discounts at giantscausewaytickets.com.
