I stayed at this AT shelter when I was doing a section hike with some friends. It's not bad as far as shelters on the AT go. There is not a water source too close to the shelter. The closest one is about 3 miles North. The sites aren't bad though, pretty flat. There is also a wooden shelter maintained by the AT, but those aren't my favorite to sleep in. Seemed nice as far as they go though.
I was hiking a little section that includes Mcafee Knob, one of the most photographed spots on the AT. This spot is really awesome. It can also just be done as a day hike, so I recommend it to anyone who doesn't mind a 8ish mile hike. Another cool thing about this area is that there's some fairly nice bouldering to be found near the top. Some of the routes are a little under maintained and mossy, but there are some fun ones. Lugging a crash pad all the way to the top isn't the most fun, but worth it if you want to get some cool bouldering in.
