$2 per night was the 50% discount for a primitive site at the 277N campground using the Golden Age Passport. Dirt/gravel sites are mostly level. Each site has a covered concrete pad with a picnic table and BBQ grill. Pit toilets are available but nothing else. Heavy but low vegetation surrounds the campground and the view is almost endless. If it’s a clear night, the sky really lights up with all the stars. There are many types of water birds around the Amistad Reservoir and boaters are seen quite frequently. If you like hiking/biking there are trails within the park and roadways outside the park. Fishing/boating/water skiing/SCUBA diving are all available on the Amistad Reservoir. Spacing between the sites is very generous. The NRA is W of Del Rio proper and there are many conveniences available in the small town. There is no Wi-Fi in the campground but we received three bars 4G on our AT&T cell phone which we used as a Wi-Fi hotspot. Our Millenicom jetpack received only a couple bars of 1X which allowed for very slow Wi-Fi. We received one Spanish OTA TV station. We camped here in a Motorhome.
