Reykjavik, Iceland

It may seem counterintuitive to contemplate Iceland in winter, but hear us out. Reykjavik bears the distinction of being the world's northernmost capital, and for many Icelandic visitors it also serves as a gateway to the rugged adventure possibilities beyond. Revitalize after outdoor pursuits in one of the many geothermal springs or luxurious indoor spas. We appreciate Reykjavik's open-minded and animated culture that includes a hip and internationally recognized music and arts scene, great food and notoriously "enthusiastic" nightlife. Moreover, it's the off season and therefore surprisingly affordable. The mere six hours of daylight only up your chances of witnessing the majestic Northern Lights. And the 40-degree temps shouldn't stop you from taking a dip outside--its celebrated geothermal spa, the Blue Lagoon, offers mineral-rich waters averaging 100 degrees.
