The Pacific Crest Trail is 2,663 mi (4,286 km) long and ranges in elevation from just above sea level at the Oregon-Washington border to 13,153 feet (4,009 m) at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks. It climbs nearly 60 major mountain passes, descends into 19 major canyons, ambles past more than 1000 lakes and tarns and passes through six out of seven of North America's ecozones including high and low desert, old-growth forest and alpine country.
The route is mostly through National Forest and—where possible—protected wilderness. The trail avoids civilization, and covers scenic and pristine mountainous terrain with few roads.
