No matter where you draw your travel inspiration from, you’ve likely seen a photo of Iceland’s Blue Lagoon. Its icy blue water has been the subject of millions of camera lenses. In 2014 the oasis drew around 700,000 visitors, which then skyrocketed to an estimated 1.3 million last year. While the geothermal spa has certainly contributed to all of the attention that the Nordic country has received, its influx of tourists is largely attributed to cheap flights to the destination and exposure from Game of Thrones. Plus, Icelandair’s stopover program makes the island nation even more accessible for travelers who are seeking an easy two-in-one trip.
