Millican Valley OHV Trail System

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 Combined 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!

Know Before You Go:

Campfires are permitted, but please keep them small and don't leave them unattended. High winds and dry conditions can fuel a wildfire even at unlikely times of the year.

Spark arrestors are required on your OHVs, year around and on chainsaws, and generators from April 1 to October 31.

Millican Plateau is open year round. North Millican and South Millican have seasonal closures.

Safety: The Millican Plateau area is remote and visitors should be equipped to be self-sufficient. Riders should wear appropriate safety gear, carry a first aid kit, and never ride alone. Most Forest Service and BLM personnel have radios and can give assistance. There is a cellular phone repeater on Grizzly Mountain and coverage is fair for most of the area.
