Moominvalley (Swedish: Mumindalen, Finnish: Muumilaakso) is a fictional place, where the Moomins live in the tales by Finnish author Tove Jansson. Especially in the early books Moominvalley is depicted as a beautiful place with green slopes, rivers, fruit trees, flowers and a place for calm and peaceful life as in the tradition of pastoral poetry, and yet it is still threatened by natural forces such as flooding and volcanoes. The valley is surrounded by Lonely Mountains in the east and by other mountains in the south, while the west faces the sea.
