The people of Iceland have long believed in the existence of elves. The elves are known as Huldufolk, which means "hidden people," and they are said to live in rocks and mountains, hiding from humans. While some Icelanders consider elves to be just myths, others still believe in them and often go to great lengths to avoid disturbing them. The idea of elves is also used in Icelandic literature and art, and they are an important part of Icelandic culture and heritage.
