The Grey Lady haunts Danesfield House and surrounding area, including the tunnel - a public footpath that goes under the Danesfield estate. Dressed in the apparel of the Roman Sisterhood with a pale and solemn face and an old fashioned lantern in her hand, this ghostly lady is often seem walking from where Danesfield Chapel once stood, down the hill past the tunnel entrance and towards the school which was formerly Medmenham Gate...and there she disappears!
Best searched for before the sun sets, you will have to face your fears before entering this dark tunnel. Although you may wish to use a torch for the journey to the geocache (the sure-footed won't need one), you might not require one to find it, just a steady nerve. (The location of the cache has been moved slightly since the tunnel maintenance. Co-ords are still the same).
