The Coolest Places Around the World From Where You Can Mail a Letter

On occasion, and only if you’re lucky, mailing a letter will involve a little more than a walk to the mailbox on the nearest street corner. But around the world, a handful of post offices occupy locations so unusual they’ve become tourist attractions in their own right. One has been hiding inside a Slovenian cave since 1819 and another sits in a houseboat bobbing on Dal Lake in Kashmir surrounded by shikara boats; there’s one perched on the slopes of Mount Everest, and there’s a place where you can send postcards from a mail office submerged underwater in Oceania. All of these are fully-functioning post offices.
