Halloween at Camera Obscura

Dizzy, the attraction's mascot, is hiding somewhere in the building five times over: as Frankenstein, Dracula, a mummy, a witch and a werewolf. You pick up a trail sheet when you arrive, tick off each costume as you find it, and the Gift Shop hands over a sweet treat once you've got all five.

The hunt runs on top of the usual floors of illusions, with themed decorations, ghostly projections, scary portraits and photo ops added along the way. On selected afternoons and evenings a witch and a mad scientist roam the building, and in the rooftop Camera Obscura show the guides add family-friendly local Halloween stories.

The house line is "spooky, not scary": silliness and surprises, no big scares. On a Royal Mile full of ghost tours selling screams, this is the gentle option. It's included in standard admission, and from 24 to 31 October tickets for entry before 9am or after 7pm are £4 off.
