Chantarelles are quite expensive here so it's easier to just go out in the forest and pick your own. We have something called allemansrätt or "freedom to roam"
In Sweden allemansrätten (lit. "the everyman's right") is a freedom granted by the Constitution of Sweden. Since 1994 the Instrument of Government says that notwithstanding the right to own property "everyone shall have access to nature in accordance with allemansrätten".
Allemansrätten gives a person the right to access, walk, cycle, ride, ski, and camp on any land—with the exception of private gardens, the immediate vicinity of a dwelling house and land under cultivation. Restrictions apply for nature reserves and other protected areas. It also gives the right to pick wild flowers, mushrooms and berries (provided one knows they are not legally protected), but not to hunt in any way. Swimming in any lake and putting an unpowered boat on any water is permitted unless explicitly forbidden. Visiting beaches and walking by a shoreline is permitted, providing it is not a part of a garden or within the immediate vicinity of a residence (legally defined as the hemfridszon). The hemfridszon's size depends on conditions but can be as large as 70 metres from an ordinary dwelling house.
