If you live within driving distance of this place, it's worth the trek.
Just got back yesterday from there. It's one of my favorite spots. Great trails (and the 8-mile AT approach trail starts at Amicalola), and great solitude. Part of the reason I like it is it's the anti-here and here and here.
In the time since I'd been to Amicalola, a switch-back staircase had been added, running the length of the falls. I recommend walking down instead of up--otherwise, you feel like you're on a Stairmaster. So when I got to the bottom, I made a loop and went back up the East trail. Not an easy route, either, but at least it's somewhat shaded and on an actual path.
Everytime I hike in the mountains, I'm reminded--somewhat painfully--that five miles in the hills is different than five miles in the flats.
