Update, as many people keep coming to this website for info: this event take place every year, usually in the Hongdae area. It’s easy to find information about this year’s gathering on Facebook. Look for ‘zombie walk’ and the event will pop up!
Yesterday was the Zombie Walk in Seoul. They’ve been doing this parade for few years and this time I joined. I tried to look like a zombie so I could infiltrate between them I take photos of these creatures!
