The Canary archipelago was sculpted by a period of intense volcanic activity; its islands possess a stark, near lunar beauty. Gran Canaria is the third-largest island in the group and is often described as the 'Round Island' for its near-circular shape. Las Palmas, its capital, is also the largest city in the Canaries numbering some 500,000 inhabitants. Despite the seemingly inhospitable landscape, farmers in Gran Canaria's Angostura Valley cultivate abundant crops of tomatoes, onions, melons, and figs. Moreover the island's climates, lack of rainfall, and fine beaches have long drawn Europeans seeking the winter sun.
