Mushroom Festivals in California 2026
7 mushroom festivals this year.
Wild mushroom season in California peaks November through February, following the first significant rains. Chanterelles appear in coastal forests from Marin to Humboldt after fall rains; morels come in spring, particularly after Sierra Nevada fires. Cultivated mushrooms (oyster, shiitake, lion's mane) are grown year-round in the Bay Area and Central Coast. Mushroom festivals and foraging events cluster in late fall and early winter when wild species are most abundant. Below are the 7 mushroom festivals on California's 2026 calendar — each with its dates, location, and a map.
