Humboldt Redwoods State Park is a state park of California, United States, containing Rockefeller Forest, the world's largest remaining contiguous old-growth forest of coast redwoods. It is located 30 miles (48 km) south of Eureka, California, near Weott in southern Humboldt County, within Northern California. It was established by the Save-the-Redwoods League in 1921 largely from lands purchased from the Pacific Lumber Company.
