One of Northern Ireland's best-known attractions, the Giant's Causeway is a remarkable natural rock formation. This UNESCO World Heritage Site was created by cooling lava millions of years ago - the thousands of basalt columns have various legends associated with them, the most famous involving a fight between giants from Ireland and Scotland. Climb atop the colums for stunning views of the Atlantic Ocean and keep your eyes open for all kinds of rare plants, butterflies, snails, and bees! You can walk the stones for free but there is a fee for parking and to enter the Visitor Centre.
Giant's Causeway is about an hour and 10 minute drive from Belfast.
