I've been on a nationwide roadtrip for a few months that now and I have tent camped alone in many sites from Florida to Arkansas to, now, New Mexico. I chose Aguirra because of its close proximity to White Sands National Park. It is a First Come First Serve site and you must pay in cash. I was lucky to find a site in the afternoon. There are many sites. Over 40. I lucked out with 43 because it is huge! It's a jilly Rocky site with no one around me and several stone fire pits, a BBQ grill, and animal proof garbage can. There are Porta John's in close proximity. I have not found any water yet. Not sure. No RV hookups. But what do you expect for 7 bucks a night. I was here over Easter weekend so it got noisy with Fiesta music and someone throwing up across from my site at midnight! Whole families come here, jam their music etc. It's Easter so whatever. There is a covered picnic table and lots of tree cover to deal with the intense NM sun. I love how this place is at the end of an ascending, remote, windy road though. It's large enough that no rangers come and bug you for trivialities.
