Big Knob, also known locally as Cedar Rock, is along a very popular hiking/mountainbiking trail in Du Pont State Forest. Access is via several trails, all relatively easy with only a couple of steep pulls to the summit. The main attraction of Big Knob, other than the fantastic views from the domes of granitic stone all along the ridgeline, are the huge patches of vigorous, but very rare and highly fragile plant communities that grow on and along the edges of the exposed rock. Look, but don't trample.
From I-85, take 276 north. Passing by Caesar's Head State Park (SC) you soon come to the NC border. Only a few miles past the border, cross the eastern continental divide (2,910 feet at that point), and look for the sign for Du Pont State Forest. There, take a right on Cascade Lake Road. At Staton Road, take a right. Within a mile you will see the Corn Mill Shoals Access area on the left. Turn into the lot and park there. The trailhead for Corn Mill Shoals Trail is directly across the road from the parking area.
