This 222-ac wildlife preserve is in the heart of Beaverton. About 5 mi of trails (1.5 mi paved) lead through mixed forests, creeks, wetlands, ponds, and meadows. The park is home to Winter Wren, Steller’s Jay and Brown Creeper, and Varied Thrush in winter. Spring migration brings warblers and flycatchers. Hooded Merganser and Bufflehead are just a few of the waterfowl that can be spotted at Big Pond in the winter, along with Great Blue Heron (year-round) and Green Heron which may winter, but is more often seen in spring and summer.
From Hwy 8 (Tualatin Valley Hwy) 1.2 mi E of Aloha, turn N on SW Millikan Way. Go 0.4 mi to the Interpretive Center. Transit: From TriMet’s Westside Light Rail, get off at the Merlo Rd/158th Station. Cross the tracks and turn L onto the asphalt path on Oak Trail, which leads into the park and eventually to the Interpretive Center (about 0.75 mi).
