Faro de Cabo Vilán Lighthouse, Wooden Boardwalk, Sand Dunes, Twilight, Galicia, Spain

A twilit lighthouse

More than 40 lighthouses—like the pictured Punta Ínsua Light, completed in 1915—guard Galicia's long, serpentine shoreline. Wander the Way of the Lighthouses and you'll eventually reach Cape Finisterre, a headland the ancient Romans thought marked the world's end, and home to an important signal light since 1853. But the end of the world isn't the end of this lighthouse-hopping tour. Drive northeast and you'll find the city of A Coruña, home to the world's oldest standing lighthouse: the 1st-century Tower of Hercules.
