Armstrong Redwoods State Natural Reserve

Armstrong Redwoods State Natural Reserve is a state park of California in the United States established to preserve 805 acres of coast redwoods. The reserve is located in Sonoma County, just north of Guerneville.

The reserve is in a temperate rainforest. The climate is mild and wet. The park receives an average of 55 inches of rainfall per year, almost all between September and June. Abundant fog during the summer months helps to maintain the moist conditions required by the coast redwoods.
