McDonald-Dunn Research Forest

McDonald-Dunn Research Forest is located just north of Corvallis and is operated by Oregon State University College of Forestry. The forest is available for day-use recreation, including hiking, biking, and horseback riding on designated roads and trails.

Because of its proximity to campus, this Forest is extensively used for university instruction and research. The forest consists of approximately 11,250 acres of predominantly forested land on the western edge of the Willamette Valley in Oregon, and on the eastern foothills of the Coast Range.

It occupies a ridge system that projects eastward into the Willamette Valley. In general, the streams and ridges extend northwest and southeast from the main ridge. The Forest is somewhat isolated topographically from the rest of the Oregon Coast Range, residing in the rain shadow created by it.  

For a first time visitor, we recommend the following trails:
