This campground is located right next to Hwy 162, which goes from Nathop to St. Elmo, along the banks of Chalk Creek. Thought right next to the road, there was surprisingly little road noise to disturb the peace and quiet. Part of that is due to the nice sound of the creek drowning out all but the loudest of noises.
The location is ideal for lots of outdoor activities. There are nearby hiking trails to nice waterfalls, fishing in streams and lakes, Jeep roads into the high country, sightseeing in old ghost towns, and whitewater rafting on the Arkansas River. You are also just minutes from Mt. Princeton Hot Springs, great for a relaxing soak.
The campground itself is in a mixed aspen and pine forest with vault toilets, water via a pump well, and trash dumpsters. Most sites are reasonably level, with nice tent pads for those who like to rough it, and with decent privacy from other sites. The host sells firewood for $7/bundle. It was well-maintained and pleasant. I would definitely camp here again.
