Unsettling at the best of times, the Blair Street Underground Vaults are even more so around All Hallow's Eve. The feeble candlelight barely touching the darkness, a movement in the shadows, the cling of cobwebs on a goose-pimpled arm... prepare yourselves for the fright!
You'll start the tour at Mercat Cross, where the city's undead will be gathered. One of them will be your storyteller, dressed in authentic costume. First you'll roam the quieter closes and wynds of Edinburgh's Old Town, full of ghoulish tales.
You'll then move underground descending into the Blair Street Underground Vaults. Here you'll hear of the city's most sinister side: body snatchers, torture, murder, hangings. Listen hard enough in the dark silence of the vaults, and you may even hear a faint echo of a centuries-old scream.
