There is a particular kind of travel that does not make it onto the highlight reels of most social media feeds. No golden hour photographs of pristine beaches, no smiling selfies at landmark monuments, no carefully composed flat lays of local cuisine. Instead, there are images of abandoned buildings reclaimed by silence, memorials that ask visitors to stand still and feel the weight of what happened in a place, and destinations that carry a gravity so profound that the experience of being there changes something in the person who made the journey. This is dark tourism — and it is one of the fastest growing and most misunderstood travel trends of the current era.
