Paranormal Investigation Teenager Fonmon Castle Paranormal Investigations For Teenagers. 6pm – Midnight For safety reasons, we kindly request that one adult is in attendance with each group of teenagers. 1 adult per 5 visitors. Come and visit Fonmon Castle as you embark on a Paranormal Investigation of the interior of the castle at night designed for a slightly younger crew. You will be guided by our own Paranormal Investigation Team who will take you through the various rooms of the castle and recount to you the experiences, findings and evidence that will have been gathered by our professional ghost hunting team. On each evening you will engage in a series of ghost tours, ghostly tales and “low key” Paranormal Investigations. You will be granted access to parts of the castle that are not available to the general public on a daily basis. WARNING – These investigations are atmospheric and thrilling and can at times produce feelings of fear and dread, it is therefore advised that you undertake these investigations at your own discretion. The castle gates are locked at 7pm sharp and no access is permitted after this time.
