Forest Park west of downtown Portland, Oregon is the largest natural forest reserve within a city in the U.S., with over 5000 acres (20 km²) of old growth forest, threaded by miles of recreational trails. Forest Park stretches for over eight miles (13 km), overlooking the Willamette River.
It is often referred to as the largest city park in the United States, but in actuality South Mountain Park in Phoenix, Arizona is over three times larger.
By the 1980s, 112 species of birds had been recorded in the park.
