Western Carolina is full of places to hike! Anywhere around Nantahala and Pisgah doesn't have designated backcountry campsites but they encourage you to use existing sites (they're not marked but you can tell it's a campsite) to minimized impact. Basically don't cut down ton of a trees just for one night of camping. I would carry a small diameter rope to hang your food (youtube has ton of videos on how to do this), because i wouldn't store food in your tent due to animals. I would try out all of your gears car camping or in your backyard in conditions similar to what you encounter in the backcountry, so you be more familiar with it them and sense how they work. Speaking of conditions in the backcountry, the temperature is colder in the backcountry due to elevation and lack of sunlight than it is in the city and the valley.
An extra insulation might be ideal until you learn what keeps you warm and what is an overkill. Also, you may want leave a detailed itinerary with a responsible person in case you get hurt and don't check in (it also help that you stick with this plan
) . It never hurts to do a ton of research and key an eye on road conditions and the weather leading up to wee hours in the morning before leaving to the trailhead.
Welcome aboard, and don't be afraid to ask specifics.
