Welcome! to the Prineville BLM's Millican Plateau OHV Trail System

General Information

The Millican Plateau is managed by the Prineville District of the BLM. The Plateau provides a variety of desert riding experiences from easiest to more difficult. There are 111 miles worth of trails for Class I/III OHV's, of which 37 miles are also open to Class II OHV's. The Four Corners Staging Area has an information kiosk providing maps and information for riders.

The Millican Plateau offers a true desert riding experience. The soils are mostly sand with rock outcrops and the vegetation is a mixture of sagebrush and juniper. The best riding season is during the winter when there is good ground moisture. There are only a couple of weeks during the winter when the trails are not rideable due to snow or frost.

The Millican Plateau is open for riding year round. During the summer, hot, dry, dusty conditions may inhibit riding. 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.

The trail system provides opportunities for Class I, Class II, and Class III ATVs. Some trails are specifically designed for Class I and Class III ATVs, which are ATVs (quads or three-wheelers) and motorcycles less than 50" in width. The Millican Plateau is not an OHV park. Off-highway vehicles are allowed on designated routes and areas only. If it is not signed as open, it is closed. Non-street legal motorcycles and ATV's are only permitted on Shared Use Roads. All other roads are closed. The trails are open to horses, mountain bikes and other recreationists so please ride sharefully.

These trails and facilities are developed and maintained for your enjoyment through a cooperative effort by the Bureau of Land Management, the Forest Service, Oregon ATV Fund, Central Oregon Motorcycle and ATV Club and many other volunteers.

Camping

There are 3 staging areas available for your OHV enjoyment. Alfalfa Curves, Corrals
and Four Corners Staging area. All 3 staging areas have an information kiosk, providing
maps and brochures about the area. In addition, each staging area also includes
picnic tables, fire rings and port-a-pottys.

The Four Corners Staging Area is large enough to accommodate groups, fifth wheels and motor homes. It is immediately adjacent to the paved road, so road conditions are good for any type of vehicle. Facilities are primitive. There is one portable toilet at the staging area. There is no water, and no garbage service. Please PACK IT OUT! Camping is also allowed at any of the many dispersed sites.

Directions from Bend: Follow Highway 20 east about 4 miles and turn left on the Powell Butte Highway. Go about a half mile and turn right on Alfalfa Market Road. Once you have turned onto Alfalfa Market Road it is 16 miles to the Four Corners Staging Area.

Alfalfa Curves Staging Area - Facilities include an information kiosk that provides
maps and brochures about the area, picnic tables, fire rings and port-a-potty.

Directions from Bend: located about 2 miles prior to the intersection of
George Millican Hwy when traveling east on Reservoir Road. You drive right by this staging area when in route to the 4-corners staging area.

Corrals Staging Area - Facilities include an information kiosk that provides
maps and brochures about the area, picnic tables, fire rings and port-a-potty.

Directions from Bend: head to the 4-Corners staging area. When you reach George Millican Hwy, turn left and head north for appx. 1.5 miles. The staging area is located on the right hand side and is posted with a sign on the highway.

Fire

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, chainsaws, and generators from April 1 to October 31.

Later in the summer, there may be restrictions on campfires, smoking, BBQs, and off-road use, so please check at the Prineville District BLM office or watch for regulations posted at trailheads, staging areas and major access roads.

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 Grizzley Mountain and coverage is fair for most of the area.

All trails in Millican Plateau area are two-way. Many of the trails are tight and narrow and are maintained in a manner to provide a primitive trail experience. Thus, there are numerous blind turns and hikers, other riders, horses or mountain bikes should be anticipated around every turn. Rocks and logs will be slippery when wet. Riding fast is hazardous and not recommended.

• Ride defensively
• Keep to the right
• Watch for other recreationists
• Single file traveling
• Don't ride in the dust of others

Soils

The dry, loose soils on Millican Plateau can be easily impacted and displaced. However, proper alignment, construction, and maintenance can minimize these impacts. Our task is to bring these trails up to standard and keep them there, which may mean temporary trail closures while work is being performed. Your task is to stay on the designated trails and areas and, as always, Tread Lightly!

Plants

Plant life on the High Desert is sparse and fragile which makes its role in the ecosystem even more critical. Not only do plants dazzle us with delicate beauty, they also help stabilize the soil, provide needed nutrients, retain moisture, and provide food and shelter for all forms of wildlife. Some of the plants are listed as Sensitive Species and are mandated to be protected. You can help protect these plants and maintain a healthy ecosystem by staying on the designated trails and areas.

Noxious weeds are plants that are not natural residents of this ecosystem. Some are poisonous, spread rapidly, and can out-compete native plants for light and water. Seeds from noxious weeds can lodge in tires or tight places on your OHV and other vehicles and can easily be transported from place to place. The spread of these weeds can be reduced by thoroughly washing your equipment before leaving home.

Wildlife

There are many forms of wildlife on the Millican Plateau. Please remember that this is their home seven days a week and that you are a visitor. You can avoid being an intruder by keeping your noise down and staying on the designated trails. When you encounter wildlife, slow down, watch and enjoy them, but keep moving.
