In Sweden, birch twigs are decorated with feathers (påskris). Children dress up as witches (påskkärringar), go to houses in their neighborhood, and give out drawings in exchange for candy. Swedish Easter eggs (påskägget) are made of paper or plastic and have chickens on them, and are filled with candy.

In Norway, it used to be traditional to travel, frequently to the mountains. Fewer people now go away at Easter. Påskekrim (Easter Crime) has become popular; people read crime stories, and crime series are produced for radio and television. Oranges and Kvikk Lunsj candy bars are popular foods at Easter.
