The Halloween Hike is an unlucky 13 mile loop around London's most haunted sites. Have fun being scared out of your wits and find suprises lurking around every corner at "The Crypt", our terrifying start and finish venue. Take part with your friends or come along by yourself and buddy up with zombies, vampires and werewolves along the way. Enjoy the spookiest atmosphere in London at the crypt and have a halloween to remember.
