Olympic National Park is an American national park located in the State of Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west side temperate rainforest and the forests of the drier east side. Within the park there are three distinct ecosystems which are subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific coast.
