Car camped at this amazing spot. GPS directions are a little off but you’ll be fine if you follow the sign for primitive camping (i.e. turn about a quarter mile earlier than the pinned location address). Great roof structure and tables.
My only caveat is there is a small sign that might have said that you’re supposed to have a permit (possibly for hunting) to use the spots or else you might face a fine. That being said, I had no problems and saw some other RV setups so it might not be enforced.
Overall, it’s a good spot on the way to Big Bend National Park but still about an hour from the park entrance, so perhaps not the best bet for visiting the park. Personally, I’d rather just pay the $10 national park fee for primitive camping.
