If you're section hiking or backpacking, this is a tough trail. Going NOBO is no joke! Do your research if you are camping on this trail. Some water sources are seasonal so don't plan on constant water sources. There are two shelters along the trail and that is where you'll find your constant water source. There are no privies so get used to squatting in the trees. Be sure to dig a hole 500ft away from water sources so you don't contaminate good drinking water. Be prepared for chilly and cold nights at the higher elevations. Always be prepared for cold weather to pop up. Elevation gain going NOBO is pretty strenuous with lots of switchbacks. Once you get to the BRP and a little further up from it is when it levels off. Going SOBO has its challenge as well once you hit the narrows. The elevation gain in there is rough with steep ledges. There are a couple of good water sources right away in between camp Daniel Boone and the camp site before the narrows. These could be seasonal water sources so make sure you're prepared with plenty to drink. Enjoy the trail! Give the trail its due respect because it'll make you work for it! It's a great training trail for anyone trying to get in shape for hiking and packaging the AT.
