Near Prineville in the Ochoco National Forest, the Round Mountain Trail (#805 / 7.5 mi.) is a good day mountain bike ride. Starting at Walton Lake, the trail climbs a long, sustained grade to the summit of Round Mountain, offering scenic views to the north. This trail rates as more difficult due to the sustained grade and pitches of over 10 percent grade. On the south side of the mountain, the trail continues down a 10 to 15 percent grade for four miles where it intersects with Forest Road 42. From here, there are three options for returning to Walton Lake: return on the trail; turn east, follow Forest Road 42 for 2.5 miles. then follow Forest Road 4210 (gravel) back to Walton Lake; or turn west on Forest Road 42 and follow it seven miles downhill to its junction with Forest Road 22, turn north and proceed seven miles to Walton Lake. Road 42 is one of the mayor log haul routes for this Ranger District.
