For a genuine fright, visit London's scariest places
Be afraid, be very afraid. As Halloween sidles up on the capital, we seek out the genuinely frightening places in this ancient and occasionally creepy city. From poltergeists in pubs to haunted hospitals, Time Out picks out London spookiest spots.
Greenwich Foot Tunnel
Finding yourself alone in the Greenwich Foot Tunnel is, at best, a deeply unsettling experience and, at worst, one that will leave you gasping for the safety of the ground above. Built in 1902 the tunnel is 370 metres long and 15 metres deep. The echos created by the sounds of fellow walkers entering the tunnel make for a very eerie experience. Access the tunnel via Cutty Sark Gardens.
