Southwest of Portland near Prineville, the Green Mountain route is a 10+ mile mountain bike ride combining the 8 mile Green Mountain Trail singletrack with forest roads.
This is a scenic mountain bike ride over rolling terrain through juniper and pine forests and openings between Harvey Gap and Forest Road 3380. The north end of the trail is accessible from the Wildcat Campground by a long (5 mile), uphill climb on a good gravel road to Harvey Gap. The trail is wide and there is the possibility of meeting an ATV, motorcycle, or horse. This eight-mile trail classified as more difficult because of a series of short, rough, steep sections. The return trip to Wildcat Campground is a steep (5 mile), downhill mountain bike ride on a secondary gravel road (Forest Road 3380) to the intersection with Forest Road 33, then north for 5 miles back to Wildcat.
To reach the mountain biking trailhead from Prineville, head northeast on US26 for 11 miles. Turn onto FS33 and park at the Wildcat CG or up at Harvey Gap.
