I've walked the east fork trail many times. It's probably one of my most favorite trail in northern Oconee. The grade is very good, the trail follows an old road bed for a good ways. At the intersection of the Chattooga trail are some very good camping spots.
This trail is not well marked. From the parking area, take the Jeep trail. Once you get to the hiking trail, do not make the mistake of taking a trail to the left when you first hear water. It's very slick and steep and leads to Raven's Cliff and Raven's Chute on the Chattooga River. Falls can be a busy place around lunch time with rafters and kayakers stopping for a break.
