The park's isolated peninsula location has created a unique habitat for numerous species, including several endemic animals found nowhere else, such as the Olympic marmot and Olympic torrent salamander. Large mammals include Roosevelt elk, black bears, mountain goats, and cougars. The coastal areas support rich marine life, including sea otters, seals, and various seabirds. The park's rivers host several salmon species, while its forests shelter numerous bird species, including the threatened northern spotted owl. This diversity of wildlife reflects the park's varied ecosystems, from marine environments to alpine zones.
Olympic National Park hosts an extraordinary range of plant life across its varied ecosystems. The park's temperate rainforests feature massive old-growth trees, including Sitka spruce, Western hemlock, and Western red cedar, some over 1,000 years old. The understory thrives with ferns, mosses, and lichens, while the subalpine regions display colorful wildflower meadows during summer months. The park protects several endemic plant species found nowhere else on Earth, including the Olympic Mountain milkvetch and Piper's bellflower. From coastal vegetation to alpine wildflowers, the park's plant communities reflect its diverse habitats and microclimates.
The Olympic Mountains, the park's centerpiece, formed through a complex process of oceanic plate subduction and accretion of marine sediments over millions of years. These mountains are relatively young, continuing to rise about 0.1 inches annually. The park's diverse geological features include glacially carved valleys, rugged coastlines with sea stacks, and the Olympic Mountains' core of pillow basalt, formed by ancient underwater volcanic activity. Nearly 60 named glaciers still crown the Olympic peaks, though they're retreating due to climate change. The varied terrain ranges from sea level to Mount Olympus at 7,980 feet, showcasing the region's dynamic geological history.
Olympic National Park's human history spans over 12,000 years, beginning with Native American tribes like the Klallam, Makah, and Quinault who lived on these lands. President Grover Cleveland established the Olympic Forest Reserve in 1897, and in 1909, President Theodore Roosevelt designated part of the area as Mount Olympus National Monument. Finally, in 1938, President Franklin D. Roosevelt signed legislation creating Olympic National Park to protect its unique wilderness, native wildlife, and ancient forests. The park was designated as an International Biosphere Reserve in 1976 and a World Heritage Site in 1981, recognizing its global ecological significance.
Olympic National Park's most distinctive features include the Hoh Rain Forest, one of the largest temperate rainforests in the U.S., with its iconic Hall of Mosses Trail. The park's 73-mile wilderness coastline features dramatic sea stacks, tide pools, and rugged beaches like Ruby Beach and Rialto Beach. Hurricane Ridge offers panoramic views of the Olympic Mountains and subalpine meadows, while Sol Duc Falls and the Sol Duc Hot Springs provide unique geological attractions. The park also contains over 3,000 miles of streams and rivers, pristine lakes like Lake Crescent, and numerous glaciers, making it one of the most diverse national parks in the country.
Olympic National Park showcases a remarkable diversity of climates within its boundaries. The western valleys receive up to 150 inches of rain annually, nurturing temperate rainforests, while the eastern side lies in a rain shadow, receiving only 16 inches yearly. Summers are generally mild and dry (July-September) with temperatures ranging from 65-75°F, while winters (November-April) are cool and wet, with snow common at higher elevations. The park's unique geography creates distinct microclimates, from the wet coastal regions to the glaciated peaks, making weather conditions highly variable and visitors should be prepared for sudden changes.

Olympic National Park encompasses three distinct ecosystems: glaciated mountains, Pacific coast, and temperate rainforest. The park protects one of the largest remaining stands of old-growth forest in the Pacific Northwest. Its diverse landscapes include rugged coastline, alpine areas, and the Hoh Rain Forest.
