Stay Safe

In Oregon, a bicycle is legally considered a vehicle, and the same Oregon road laws apply. Please “be seen” and practice safe riding. Vehicle traffic, farm equipment and narrow shoulders exist on many Oregon roads, and you may find that construction projects, traffic or other events may cause road conditions or signage to differ from the map results, ride descriptions and directions. For travel options plus weather and road conditions, visit, call 511 (in Oregon only), 800.977.6368 or 503.588.2941. Routes listed on this website are for informational purposes and intended as a reference guide only.

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).
