Oaks Bottom Wildlife Refuge

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 140-ac floodplain wetland is on the E bank of the Willamette River in the heart of Portland. Common residents include Red-breasted Sapsucker, Bewick’s and Winter Wrens, Hutton’s Vireo, and Western Scrub-Jay.

The Refuge also hosts warbler and flycatcher flocks during migration. Fall migrants include Semipalmated Plover and American Pipit. Bald Eagle nests on islands nearby.
