Dalarna is a region of rolling forested uplands centred on Lake Siljan and the Dalälven river valleys, rising toward the Scandinavian mountains and open fells in the remote northwest. Lakes, bogs and low hills break up an otherwise heavily wooded interior. The province is dominated by boreal coniferous forest of Scots pine and Norway spruce mixed with birch and aspen. Chanterelles favour mossy spruce and birch ground, while porcini and other boletes thrive on the drier pine heaths and forest edges.
Dalarna has a cold, fairly continental climate with long snowy winters and short warm summers. Reliable late-summer and autumn rainfall keeps the forest floor moist, which suits a long fungal season. This is classic Swedish mushroom country with vast accessible forest under allemansrätten, the right of public access. Expect strong harvests of chanterelles, funnel chanterelles and porcini from late summer into the first frosts of autumn.
