McDonald State Forest is an often-overlooked place in Oregon, which is a shame, because it’s a true treasure. McDonald-Dunn Research Forest is located just north of Corvallis and is operated by the Oregon State University College of Forestry. The forest is available for day-use recreation, including hiking, biking, and horseback riding within the park’s 11,250 acres. Within this natural wonderland, the Old Growth Trail is an easy, 1.5-mile loop that leads to some of the most breathtaking forest in all of Oregon. Lace up your boots and get ready for an only-in-Oregon adventure at McDonald Forest.

McDonald-Dunn Research Forest is located in the Willamette Valley, just north of Corvallis, Oregon.
