Kakslauttanen Arctic Resort, Finland
More than 150 miles north of the Arctic Circle, this romantic frozen paradise is famous for its signature glass igloos, allowing guests to fall asleep under the rippling night sky. There are an array of Winter activities if you start to get cabin fever, but with the available private saunas and cozy digs, you might never want to leave your room. And for the extra bold, you can opt to spend the night in a genuine ice igloo (just be sure to bundle up!).
