Witches Rocks has a few interesting problems. Most notably, there is a tall arete on the main cliff line (just uphill of the tilted-cube boulder). That arete can be climbed on both sides of the corner, and allows for a number of interesting eliminates.
The tilted cube boulder is home to a couple of fun, low-ball problems, that appear on several videos posted on athens bouldering. The so-called "Witches Traverse" starts left of the arete, moves along the angled lip of the boulder before firing up the arete. The other problem, starts on the left, and after a friction scum on the side, fires up the arete.
In general, there are several moderate problems and a couple of interesting medium hard problems. This can be a fun place to take young children because of the easy featured slab routes in the vicinity of the routes mentioned above.
Getting there. Witches is on the hilltop to the SE of campus. See overview map for location. From the KFC / Sonic, head east on Stimson, turn right before passing under the highway. Then turn left onto Rock Riffle road (rather than getting on the highway). Pass under the highway, part in the turn off on the left-hand side of the road. See map view photo below. Head towards the exit ramp, and follow the obvious climbers trail up the hill.
