Sinkyone Wilderness State Park preserves a remote, rugged stretch of northwestern California coast in Mendocino and Humboldt counties along the Pacific Ocean, an isolated landscape often associated with the Lost Coast because access by major roads is limited. The park is named for the Sinkyone people, whose homeland included this shoreline and who relied on its resources, especially ocean fish and meat that were vital in winter. Later, industrial trails and roads opened the area to logging and tanbark extraction for San Francisco tanneries, and logging continued well into the 20th century. Its enduring significance lies in how isolation has helped preserve a strong sense of wilderness.
