In (Madrid, at least) Spain, it’s a sorta huge deal in schools, with every kid under 14-15 dressing up, a lot of schools doing costume parades, and many classes giving out candy and watching movies. But outside of school, it’s all but ignored. You’ll see little kids in costumes and a few bar events, but no trick or treating and no decorations.
The much bigger day/event is carnival, for which kids wear costumes again and there’s a big parade in most cities.
