Trail begins right before Starr Mountain #190 sign and turns into the woods. Trail is marked good the first half. One sharp turn about a mile in is easy to miss. There are quite a few large lose rocks. Once to the switch backs your almost to the top of Starr Mtn. On top of the mountain it's a nice ridge walk.
It starts on an old logging road, so it's easy to follow for the first mile or so, but the trail disappears around the point where its supposed to climb the eastern slope of the ridge. Since I only had a couple of hours to spare I decided to postpone a stricter search for another day. An alternate way to reach the summit is via the Coffee Branch Horse Trail starting out of the Lost Corral Campground.
Alltrails Pro doesn't show the trail on its GPS.
