This national park in far northwest California is filled with giant redwoods—including the tallest tree in the world. The park’s mosaic of habitats includes prairie/oak woodlands, mighty rivers and streams, and 37 miles of pristine Pacific coastline. An amazing diversity of life exists at Redwood National and State Parks. The ancient coast redwood ecosystem preserved in the parks contains some of the planet’s most majestic forests. Along with the national park, three adjoining state parks are also open to visitors. These are Prairie Creek Redwoods State Park, Del Norte Coast Redwoods State Park, and Jedediah Smith Redwoods State Park. Together with Redwood National Park, they comprise some 45 percent of all the old-growth redwood forest remaining in California. These parks combined are listed as a World Heritage Site and International Biosphere Reserve, protecting resources cherished by citizens of many nations.
