With its majestic redwood groves and 33mi of beaches, this 106,000-acre site encompasses three state parks: Prairie Creek Redwoods, Del Norte Coast Redwoods and Jedediah Smith Redwoods. In 1968 Congress set aside 58,000 acres of land to be preserved as Redwood National Park; another 48,000 acres were added 10 years later. This park, which contains some of the world's tallest trees, has been designated a World Heritage Site and an International Biosphere Reserve. Within Redwood National Park, campsites abound, but motels are few. Trinidad and Crescent City, at either end of the park, provide the widest selection of accommodations and other services in this area. There are five visitor centers along the 40mi section of US-101 that runs through the park, all of which have maps and sponsor ranger-led programs. The National Park Service's Thomas H. Kuchel Visitor Center, on US-101 1mi south of Orick, has exhibits on the park's fascinating history. Lady Bird Johnson Grove has a 1mi level nature trail around a stately old-growth forest named for the former First Lady. Fern Canyon features a variety of lush ferns clinging to steep bluffs. The Newton B. Drury Scenic Parkway, a 10mi scenic drive through ancient redwoods, rivals the Avenue of the Giants in its awe-inspiring splendor. There are 70mi of hiking trails.
