We were coming from NC, so we got on 276 south out of Brevard. Just as soon as we crossed in to SC, the road to the falls, Solomon Jones Rd, turns left. There's a sign for Camp Greenville also. Go 4.6 miles and there's a small unmarked parking area on the right for visitors. There's a road on the left that goes up to some activity areas for the camp. The 1/2 mile trail is just back down the road a few feet and is very obvious. It starts off fairly easy, but then gets extremely steep as it descends into the gorge. There are plenty of roots and rocks for foot and hand holds, but I wouldn't recommend it if you can't lift your knee above your waist. It took us 20 minutes to get down and 30 to get back out. The trail comes out on the right side of Cox Camp Creek. It crosses the creek below a lower cascade (next photo), then it's fairly easy to climb around up towards the main falls for some better views.

The next 3 shots are from different angles. We got there mid morning and had the place to ourselves for about 1.5 hours. Then a group of about 20 from the Camp showed up, so we left.
