Not for the faint-hearted – this walking tour takes you around the Old Changi Hospital (read: not in). Led by the adventurers of Explorer SG, the Halloween special tour shines a torchlight on the history of the abandoned hospital and its current reputation for being one of the spookiest places in Singapore.
A prime spot for ghostbustin', it's said to be haunted by the restless souls of those who were tortured to death or executed by the Japanese during World War II when it was used by the Kempeitai (Japanese military police) to hold more than 50,000 Allied prisoners-of-war. Do note that there's a waitlist for available slots, and only those on the 'going' list on its Meetup page are able to attend.
