The Millican Valley Off-Highway Vehicle (OHV) Trail System consists of lands southwest of Prineville, Oregon along George Millican Road, extending south of Highway 20. Trails and play areas are provided for Class I, II, and III off-highway vehicles (OHVs), although other trail users can use these trails as well.
The Millican Valley OHV trails and facilities are managed by the Central Oregon Off-Highway Vehicle Operations (COHVOPS) team, a partnership between Prineville BLM, Deschutes and Ochoco National Forests and Oregon Parks and Recreation (ATV Program). Many local ATV, OHV and motorcycle clubs and organizations also contribute to this program, and many volunteers have donated long hours of hard work to make this a high quality riding area. Fees from your ATV registration sticker make this possible!
