An abandoned trail leads from the lower end of the unmaintained Twin Springs Campground two miles down to the Roaring River.
Trail very faint after the second stream crossing, disappearing shortly after the crossing of Plaza Creek, about 1.7 miles from the Trailhead. Trail is faint in places but reasonably well flagged.
Not recommended for the average hiker. Stamina and navigational skills required.
The nearby Plaza Ranger Station was named by T.H. Sherard of the Forest Service because of a natural plaza or clearing, which afforded a fine view of Mt. Hood.1
This trail needs some friends and some further exploration. It would be interesting to see if someone can find where it joins with the trail that used to go east/west along the roaring river. Shows on some maps (here is one example). Dropped from USGS.
