Millican Plateau OHV Trail System
The Millican Plateau is managed by Central Oregon Combined OHV Operations for the Prineville District of the BLM. The Plateau provides a variety of desert riding experiences. The soils are mostly sand with rock outcrops and the vegetation is a mixture of sagebrush and juniper.
There are 111 miles of trails open to Class I (Quads, 3-wheelers less than 50" wide and 800 pounds) and Class III (motorcycles) ATVs, 37 of these miles are also open to Class II OHV's (side x sides, jeeps, etc). The trails are open to horses, mountain bikes and other recreationists so please ride sharefully.
These trails and facilities are operated and maintained for your enjoyment by Central Oregon Combined OHV Operations (a Forest Service, & Bureau of Land Management Cooperative agreement), Oregon Department of Parks and Recreation ATV Funds, support from various user groups and many other volunteers.
General Information
Seasonal Information
The Millican Plateau is open for riding year round. During the summer, hot, dry, dusty conditions may inhibit riding. The best riding season is during the winter when there is good ground moisture. There are only a couple of weeks during the late fall, winter and early spring when the trails are not rideable due to snow or frost. Individual trails may be closed temporarily for maintenance and reconstruction or to protect resources. Extreme fire conditions or snow may also close the Plateau for short periods of time.
