Edinburgh is a city that boasts about its dark side!  There are many tours that offer to take you around town, with their own twists on the macabre happenings of the past (We’ve included some of these below)! My recommendation is to pick one and do it!  Murders, hangings, unfulfilled dreams – you get to hear about it all – sometimes from someone dressed and sounding like a ghost.  We continued this journey with Sandemans and our tour guide was scary….see featured image! Just be prepared to hug your younger ones if they are spooked.
