East of Gold Beach in the Siskiyou National Forest, the Lower Rogue River Trail (#1168) is a 12 mile route open to mountain biking. It can be combined with FS33 for a nice loop. The route runs through dense old growth Douglas Fir forest with occasional river views. It crosses several private property in-holdings, so make sure to stay on the trail. There are several rocky scree sections that may require walking the bike. There are numerous creek crossings.
The trail follows the Rogue River on the northern bank from the eastern upstream location near Agness to the downstream western location near east of Gold Beach at the end of FS335.
To reach the western trailhead from Gold Beach, head east on Jerrys Flat Rd for 9.7 miles. Turn left heading northeast on FS3310 for 0.2 miles crossing the bridge. Just across the bridge, turn right heading east on single-lane FS3335 (unsigned) for 2.2 miles. Veer right heading east down FS335 (unsigned) to the trailhead.
To reach the eastern trailhead follow FS33 into Agness. The trailhead is located at the old post office from 1807. Do not park at the post office. Instead, park at the nearby Forest Service Guard Station.
Overall, Lower Rogue River Trail is the 18th most popular mountain bike trail of all 55 mountain biking rides in Oregon.
