This is one of the better waterfalls I've seen, certainly the best in Georgia. The only complaint that I have is the stairs that make up the trail are somewhat obtrusive, and the bridge at the base of the falls detracts from the spectacular scenery.
That said the trail is nice, but strenuous. It's kind of like a never ending stair-master. One other comment, I brought my dogs and the metal grating of the staircase was hard on their paws. My dogs are pretty fearless, so the view through the grate didn't particularly bother them, but other dogs might not handle it as well.
I took the loop back to the base of the falls, and that was much more problematic. It is very poorly marked (The trail has markings, but the colors change and it forks frequently, all of which are marked), several times I became afraid that I was lost , or at least going in the wrong direction. It is also extremely steep, without stairs, and I had to let the dogs off leash so that I could grab trees to keep from rolling down the mountain. Fortunately, my dogs are trail trained and didn't run off, but be aware that trying to handle dogs that pull on this trail would be bad.
On a sad note, this was the last trail my dog Buddy did with me. He passed away from cancer about a week after we got back to Colorado, but if this had to be his last major hike, it was a good one for him.
