Olympic National Park is one of the most ecologically diverse parks in the entire national park system, encompassing four dramatically different regions: alpine, Pacific coast, temperate rain forest, and the drier east side of the Olympic Peninsula. It was designated a National Monument by President Theodore Roosevelt in 1909 and elevated to National Park status by President Franklin Roosevelt in 1938. Today it’s also a UNESCO World Heritage Site and International Biosphere Reserve.
