I have investigated the reported ghost sighting previously so this journey was to get some photos so you can check it out.
Have a look.
What originally took me out there a few years back was a report on a forum, in which a local reportedly witnessed a ghost near the old quarries. They had been walking along the walking track and near one of the quarries, near the old powder magazine, they saw a man in older styled clothes walking about aimlessly before disappearing.
There have been deaths both in quarrying accidents killing prisoners and guards and also at least one poor chap who fell to his death.
