Visitors: About 3 million visits in 2013. About 150 million since 1938 when the park was established.

How big: 922,651 acres

High and low: From Mount Olympus, 7,980 feet, to sea level.

How wet: 50 to 70 feet of snow can fall annually at Mount Olympus. Down low, some forests on the park’s west side get 12 feet of rain a year.

Really big trees: Thanks to all the rain, Olympic has some of the last primeval temperate rain forests in the continental United States. Trees (dominated by Sitka spruce and western hemlock) can be hundreds of years old and more than 200 feet tall.

Wild things: From marmots to elk and bears, salmon to owls and eagles, an abundance of wildlife inhabits the park, including 300 species of birds; 56 mammal species and 20 reptile/amphibian species.

Tribes: Eight tribes have traditional links to what’s now the park: Hoh, Makah, Quileute, Quinault, Skokomish, Jamestown S’Klallam, Elwha Klallam and Port Gamble S’Klallam.

Trails: 611 miles on which to wander.

Glaciers: Lots — with 60 glaciers named — although all are shrinking with climate change. (Glacier National Park in Montana, despite its name, has only 26 glaciers left.)

Water world: More than 3,000 miles of rivers and streams plus big lakes (Ozette, Crescent, Quinault). And 73 miles of Pacific coast.

Peaks: The Olympic range, much of it within the park, is a sea of jagged mountains with dozens of peaks that top 6,500 feet.
