Reykjavík has a way of defying expectations. Just below the Arctic Circle, it’s the world’s northernmost capital, but thanks to the Gulf Stream the climate is fairly moderate. Beyond that, there’s a warmth of spirit here that seems to sustain people through winter’s darkness until the long June days when the sun sets at midnight and rises again three hours later. Music, theater and visual arts are flourishing, and the nightlife is considered some of Europe’s most exciting. Capitalizing on Iceland’s abundant geothermal springs, Reykjavíkers and visitors alike adore a good soak -- especially in the luminous turquoise waters of the nearby Blue Lagoon, the country’s most popular attraction.
