Starting your tour at the Mercat Cross, you will explore Edinburgh's ghostly past on a guided tour through the streets of the Old Town and its underground vaults. Listen as your cloaked guide tells you tales of the city's dark and grim past as you are led along the Royal Mile.

If you dare, step into the narrow alleyways, which are only a few feet wide. Make your way to the South Bridge, and head underneath, where Edinburgh's Vaults are located. Once storage areas for businesses and shops in the area, the vaults were taken over in the late 1700s and turned into living spaces. Eventually, the area became home to slums and the city's red-light district.

As you walk through these now-vacant rooms, you will hear tales of the deplorable living conditions, as well as of the crime that once raged through the vaults. When you emerge from the underground, consider yourself lucky that it isn't in the dead of night.
