Redwood National Park

The Redwood National and State Parks are a complex of one national park, one County park and two California state parks located in the United States along the coast of northern California. The combined RNSP contain Redwood National Park, Del Norte Coast Redwoods County Park, Jedediah Smith Redwoods State Park, and Prairie Creek Redwoods State Park. The parks' 139,000 acres preserve 45 percent of all remaining old-growth coast redwood forests.

Located in Del Norte and Humboldt counties, the four parks protect the endangered coast redwood—the tallest, among the oldest, and one of the most massive tree species on Earth—which thrives in the humid temperate rainforest. The park region is highly seismically active and prone to tsunamis. The parks preserve 37 miles of pristine coastline, indigenous flora, fauna, grassland prairie, cultural resources, waterways, as well as threatened animal species, such as the Chinook salmon, northern spotted owl, and Steller's sea lion.
