Plenty of campsites here in the Rio Grande Village. Easiest way to pay is with cash, and you just reserve your campsite at the self-pay station. We payed with a card at the Rio Grande visitor's center (closed in the summers). If you don't mind other people being close to you, this is the campsite for you. My boyfriend and I camped here for one of the nights we stayed in Big Bend. We wanted a more secluded spot which you can find further back in areas of campsites available, but it's first come, first serve style here. Bear boxes are provided at each campsite. The campsites further back have better shade, but we were able to find some trees to set up under. The only thing we didn't like about the campsite was the proximity to people using generators. They have a separate area for RVs, but some people brought their campers. The generators were somewhat loud, but we were able to sleep through the noise. We definitely prefer more natural campsites, but this one was fine for what we needed that night. Not too far of a drive from the Hot Springs trail either.
