The Redwood National and State Parks (RNSP) are a complex of one national park and three 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 State Park, Jedediah Smith Redwoods State Park, and Prairie Creek Redwoods State Park. The parks' 139,000 acres (560 km2) preserve 45 percent of all remaining old-growth coast redwood forests.

Del Norte County is a county at the far northwest corner of the U.S. state of California, along the Pacific Ocean adjacent to the Oregon border. Its population is 27,743 as of the 2020 census, down from 28,610 from the 2010 census. The county seat and only incorporated city is Crescent City. Del Norte was pioneered and populated by Azorean Portuguese settlers and dairy farmers, which may account for the local pronunciation of the county name. Locals pronounce the county name as Del Nort, not Del Nor-teh as would be expected in Spanish.
