With gruesome stories of past murders, and an ideal setting for the fantastic world of Harry Potter, London is the perfect Halloween destination. Retrace Jack the Rippers macabre haunt for blood, or if you believe in vampires, head to Highgate Cemetery, where if you don't meet Lestat, you will get scared by its cracked open catacombs. Think a beer will cool you off? Then avoid The Ten Bells at all cost! Be afraid, be very, very afraid.
