Middle Earth can be a very confusing area to visit. It is climbed in much less often than the Outlets, so expect solitude on most routes. Many routes require the better part of a rope length, requiring two ropes to rappel. Some good climbs are Hrum Hroom and Three Rings for the Elven Kings (very popular though).
Follow the signs from Hill City to Sylvan Lake (same as the Outlets). Hike around the lake heading north from the car. Walk through the Outlets until reaching the field north of Outer Outlet. From here, walk up the hill on the trail using switchbacks. At this hill crest is where Middle Earth begins. A left up another hill brings one to Hrum Hroom and Quickbeam. Most routes are located by heading down the hill from this crest and heading up gullies between rock formations.

Also, if I remember right, it might be possible to get to the top by scrambling up a back way. I am not sure on this, however....[more] Browse More Classics in SD
