Giant's Causeway steals the spotlight that filters through the sea mist of Northern Ireland's Causeway Coast. Venture beyond the basalt columns, however, and you'll discover scores of Blue Flag beaches, including Portstewart Strand. Flanked by cliffs and the River Bann, this stretch of golden sand in Londonderry is caressed by the Atlantic. In nice weather, you'll find a healthy amount of picnickers, surfers and sand-castle builders here. For respite, head into tufted dunes populated by butterflies and wildflowers (you can join the Causeway Coast Way trail) or visit neighbouring Portrush where the limestone cliffs of Whiterocks Beach have been carved by the waves. The Cathedral Cave is spectacular.
