Blue Mountain/South Fork OHV Trails

Motorcycle rider of forested OHV trailThe OHV trails in the Blue Mountain area are located in the South Fork Burnt River watershed west of Unity, Oregon and extend north towards Sumpter, Oregon. The main trail is the Blue Mountain OHV Trail #O-1972 with shorter side and loop trails (#O-1972A to O-1972D) which add some challenge and other experiences along the way. Although these trails have been designated for OHV use since the early 1990s, they are also open for use by hikers, mountains bikes and equestrian visitors. In 2013, the Forest began to develop the South Fork OHV trails which are centred around the South Fork Burnt River area and connect to the Blue Mtn OHV Trails.


Development History

Early development efforts for this OHV trail system began in the early 1990s with the idea to provide OHV trail riding from campgrounds and trailheads in the South Fork Burnt River area north to the Blue Mountain Summit west of Sumpter. Although some new trails would be constructed, much of the original 70 mile system would be developed by converting decommissioned roads into trails. To provide for these riding opportunities, an Environmental Assessment was completed in 1992. Next construction grants were submitted by local recreation managers on the Unity Ranger District to the Oregon Department of Transportation that managed the grants at that time.  Construction grant funds were awarded in late 1990s.

In 2007 additional ATV trails were approved with the South Fork Burnt River Watershed Travel Management Plan. The decision approved the construction of over 40 miles of new trails. To implement the construction, a grant from the Oregon Department of Parks and Recreation was awarded in 2006, and development completed in 2007.

Riding Opportunities

There are about 56 miles of trails in this area. All of the Blue Mountain/South Fork OHV trails are designed and maintained for vehicles less than or equal to 50 inches wide. An Oregon ATV Permit is required to operate an OHV on this area, and other public lands in Oregon.
