Introduction

Cougar Mountain Regional Wildland Park is the most expansive wilderness preserve in Seattle's eastern suburbs, spanning about 3,000 acres with over 36 miles of winding trails, a rare destination for deep hiking near a major Pacific Northwest city. Centered on 480-meter Cougar Mountain, named for cougars that roamed here in the 1800s, the park still hosts black-tailed deer, black bears, coyotes and various raptors though large cats are now rare. Trails pass through dense old-growth Douglas fir and western hemlock forest, past abandoned 19th-century coal mine sites and anti-aircraft missile base ruins, weaving natural ecology with Cold War history. The summit offers views of Lake Washington, Bellevue skyline and distant Mount Rainier, making it Seattle residents' favorite weekend escape into wilderness.
