About the only party for Halloween in Munich is the one for adults; this one, for example, pulling in well known DJs to rock the house. Halloween is largely missed in Munich. You really see very few signs of it, and if you want the kids to go trick-or-treating, you have to find some international organizations that are hosting events. Halloween is most often associated with the United States, but if you want to see the biggest Halloween celebration in the world, you go to the town of Derry in Northern Ireland. It’s their own version of Carnival, but in the Halloween spirit. I actually didn’t realize that Halloween has its origins as an ancient Celtic festival known as Samhain. It’s the celebration of the end of the harvest season, and is sometimes regarded as Celtic New Year.
