East of Spray in the Umatilla National Forest, the West End OHV Area (aka Sunflower OHV Area) has 91,000 acres open to ATV trails riding on various old roads.
To reach the Fairview Campground trailhead from Spray, head east on SR19 for 3 miles. Turn left heading north on SR207 for 11 miles. The campground is on the left.
From the campground, the trails are to the east on NFD 24 and NFD 23. Although no formal ATV routes are designated, the terrain allows for some off-road travel and there are numerous unused or low standard roads. Pay attention to land boundaries as there are areas of private land within the riding area boundary. ATV roads open to standard vehicles must comply with Oregon State vehicle laws. The area is made inaccessible by snow to all but snowmobiles during winter months.
Note: Oregon State Park ATV decal is required. All paved road and double-lane gravel roads are closed to ATV riding.
Note: As of September 2007, ATV riding on Forest Service roads is limited to designated routes as long as the ATV has a valid Oregon ATV sticker. The designated Forest Service roads are all signed as open to ATV riding. Do not ride on unsigned roads.
