Northeast of Prineville in the Ochoco National Forest, the Green Mountain system is 8.5-mile trail winds along open ridge tops, which offer spectacular views, and passes through beautiful old growth ponderosa pine stands. This trail offers a wide range of scenic views and riding experiences. In the spring, there is a beautiful array of wildflowers. The elevation ranges from 4500-5400'.The trail is open year round unless closed from snow, high fire danger or wet soil conditions.
The trail is designed for Class I and Class III ATVs which are ATVs (quads or three-wheelers) and motorcycles less than 50 in width. The Green Mountain Trail is not an OHV park. Off-highway vehicles are allowed on designated routes and areas only. The trails are open to horses, mountain bikes, and other recreationists, so please watch for others and ride sharefully.
To reach the trailhead from Prineville, go north on North Main for about 4 miles. Stay right at the Y and follow McKay Creek Road 27 about 10.3 miles to the junction with Road 33. Follow Road 33 for 4.5 miles to the trailhead at Harvey Gap.
Note: As of September 2007, ATV riding is only permitted on Forest Service roads numbered with three digits. Also, all ATVs must have a valid Class 1 permit. ATV riding is not permitted on two digit or four digit numbered Forest Service roads.
