If you are a tent camper or don’t mind boondocking the campgrounds are fine. They to have clean flush bathrooms and there is a dump station with potable water. 

Frijoles Canyon is an ecotone, the transition zone between two different plant communities, as that between forest and prairie.  Frijoles Creek flows into the Rio Grande 2 1/2 miles fr the canyon. It provides water and life to an otherwise dry and hash area. 

This canyon was occupied by ancestral Pueblo people for hundreds of years. They were cave dwellers. 

At the visitors center are maps of the trails. One starts at the center and takes you through a number of cave dwellings, a village and the lush canyon floor. 

If you are in the area, visit Bandolier. The caves are amazing and the scenery is also.
