Giant's Causeway, Bushmills

Considered the country’s fourth-greatest natural wonder, World Heritage-listed Giant's Causeway is an area of about 40,000 interlocking basalt columns, formed by ancient volcanic eruptions. Most of the columns are hexagonal, with the tallest rising 12 m (39 ft) into the air. Some of these rock structures, after several million years of weathering, resemble easily recognizable objects. These include the Organ, Giant’s Boot, Giant’s Eyes, and Camel’s Hump. Visit the area to see and photograph a wide variety of native seabirds, such as cormorants, redshanks, and razorbills. The weathered rocks shelter a number of rare and unusual plants, including sea spleenwort, sea fescue, and frog orchid. Stop by the visitor center for more information, souvenirs, and refreshments.
