Yes it's a parking lot but you're surrounded by mountains!
Just like others have said, the RV camping is a parking lot. But when we were there in mid September, there only maybe 6 or 7 "RVs" camping. Most of the traffic was people parking for the trail head. Speaking of trails, the hiking from this campground is spectacular! Guadalupe peak was the trail everyone came to do, but there are multiple others that are just as beautiful. On those trails we were the only people our hiking. There is a nice restroom facility and potable water. You cannot hook your RV up to the water pump so bring a large jug to help fill up your water tank if needed. There is also a water bottle filler in the restroom building. The tent camping area is nice, with defined sites, not a parking lot 😉 You can run your generator until 8pm, although not many did. It cools down in the evening in mid September which was good for sleeping. There is no dump station. The views from the campground are great and the sunrise and sunset light is phenomenal.
