The Swedes have a word for it: smultronställe. Literally "wild strawberry spot," it's best translated as a quiet, almost mystically beautiful haven, somewhere hidden away from the rest of the world — a place that feels like it exists only for you. I knew the term from studying Swedish in college, but the meaning never sank in until I traveled to South Koster Island last year for a taste of how the Swedes summer. Though it's less than three hours by car and ferry from either Oslo or Göteborg, the Koster archipelago, which sits within a protected marine preserve off Sweden's wild western coast, feels light-years away from Scandinavia's legendary coolness.
