Olympic National Park is a United States national park located in the state of Washington, in the Olympic Peninsula. The park has four basic regions: the Pacific coastline, alpine areas, the west side temperate rainforest and the forests of the drier east side. Inside the park, the Olympic mountain range is nearly circular, contoured by 13 rivers that radiate out like the spokes of a wheel. No road traverses the park, but a dozen spur roads lead into it from US 101, making it easily accessible from outside the park.
