I have stood on both of these summits, but I accessed them with my mountain bike in the past. I decided to hike them from the Deer Creek Canyon Park Trailhead and add the mountains to my peak list. The Plymouth Creek Trail was slick and icy nearly the entire way. When I got to the west of Plymouth Mountain I just bushwhacked east to the summit. On the way out, when I got to the south of Bill Couch Mountain I just bushwhacked north to the summit.
