Declared a national monument in 1909 and a national park in 1938, the 1406-sq-mile Olympic National Park shelters one of the world's only temperate rainforests and a 57-mile strip of Pacific coastal wilderness that was added in 1953. It exists as one of North America's last great wilderness areas. Opportunities for independent exploration abound, with visitors enjoying such diverse activities as hiking, fishing, kayaking and skiing.
