Reservations only, but we were able to reserve online while surveying campground to see what was open: https://newmexicostateparks.reserveamerica.com/ (on way north so stopped for a night, getting there late afternoon).

Pretty basic. Most sites have no shade except for over picnic table. Lots of flying things: flies, mosquitos. Many stickers (so walk dog carefully). 

--->At 02:30 in morning a drone very noisily buzzed us and sounded like it circled us for what seemed like 5 min. Not sure what that was about.... Racoon walked up to door screen and pawed at it while we were making dinner.
