At Icehotel, guests chill out in rooms made completely from ice and snow. “It’s like walking into a world of your dreams,” says Icehotel press and media manager Josefin Lindberg. “It’s like you’re in a fairy tale.” Artists from around the world come together each year to recreate the magical dwelling. To get the job done, they use more than 3,000 tons of ice from the nearby Torne River. The majority of the hotel melts each year when the weather grows warm. But Icehotel 365, which launched in 2016, lets visitors experience the wonderland all year long, at 23°F. In warmer months, it’s chilled using refrigeration that’s powered by solar panels. —Rebecca Katzman
