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.
This trail use area provides year-round riding for Class I, II and III users and includes 255 miles of designated routes, nine staging areas, and three play areas.
Trails in the Millican Valley are designated with varying difficulty levels to allow visitors to choose trails according to skill levels and ensure a safe and enjoyable experience.
The Millican Valley OHV trails and facilities are managed by the Central Oregon Off-Highway Vehicle Operations, 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!
From Bend, OR: Take US-20 east approximately 2.5 miles, then turn north onto the Powell Butte highway and proceed another mile to the roundabout. Take the first exit onto Alfalfa Market Rd (which becomes Willard Rd, then Reservoir Rd) and proceed east for another 16 miles. The Four Corners OHV Staging Area will be on your right.
