Nearly 10,000 people gather for this apocalyptic-style event, featuring elaborate costumes of the undead. Definitely not for the faint of heart, this spooky event has become synonymous with Halloween in the city. And every year, more and more people are joining the fun. Whether you want to dress up, or simply take a peek at what the world might look like if zombies really did take over, it’s an interesting way to spend a fall day, at the end of October, in Montreal.
