Now through October 31, 2018. A beautiful Scottish estate by day and a Haunted Forest by night!. At Kelburn Castle and Estate in Fairlie, about 40 minutes west of Glasgow, the forest trail is transformed into a spooky, chillfest for the Halloween season. Make your way through the narrow, dark paths of the Secret Forest with live actors playing bloodthirsty clowns, ready to scare you in a Carnival of Horrors. This 30 minute experience is recommended only for brave souls and those over 15 years old.
