A variety of sites
Located a few miles away from the Cumberland Gap visitor's center, the camping area abuts the highway (where you can still hear traffic) and after a short drive into the park, you'll come across a plethora of camping sites.
There are RV sites with power and water and for tent campers, you can choose between large spaces with open fields and hilly, shaded spots for a more secluded feel. There are also food lockers on-site to discourage wildlife, and flip-up fire rings that, for once, weren't clogged with ashes and old wood.
Speaking of fires, you can buy firewood on-site from the camp store (no cards taken).
There are care stations with toilets and showers in three locations, spaced evenly throughout the 6 rings that make up the park.
Cell service is decent, with 2-3 bars of LTE.
