The standard route is short. From the gravel pullout on Forest Road 140, the Courthouse Falls Trail drops about 200 feet through hardwood and rhododendron to a wooden-railed overlook at the head of the cove. Total round-trip distance is 0.8 mi; total time is 30 to 45 minutes at a normal pace. The trail crosses Courthouse Creek on a log footbridge with a single handrail and has a short set of wooden steps where the slope steepens. Both stay damp because the cove holds little direct sunlight, and the Forest Service trail page specifically notes that all log bridges and wooden steps can be slippery.
The unsigned base spur is where most visitors actually want to go. About 0.15 mi past the overlook, an obvious user path drops left toward the plunge pool. It is rooted, slick, and steep enough that you will use both hands on the descent, but it is short. The spur is the only way to reach the swimming pool, and the only angle from which the curving rock walls fully read as an amphitheater.
Forest Road 140 itself is the real access question. It is unmaintained gravel branching off NC 215 about 6 miles north of Balsam Grove, rough but passable in a passenger car when dry. After significant rain or any snow it can rut deeply, and in winter it is regularly impassable for low-clearance vehicles. There is no fee, no America the Beautiful pass requirement, and no formal lot. The pullout holds 8 to 10 cars, fills by 10 a.m. on October Saturdays, and spillover parks along FR 140 on the shoulder.
