Ireland: Giant's Causeway

Giant's Causeway

The only World Heritage Site in Northern Ireland, the Giant's Causeway is one of the world's truly must-see destinations. Once said to have been built by giants, the 40,000 or so hexagonal columns were actually formed by volcanic eruptions. The legends that surround this area run deep, however, and visitors may get swept up in the myths of massive men and shipwrecks—Girona of the Spanish Armada foundered here in 1588—by walking among the stones.
