We just got back from Colorado and spent a couple of delightful days at Trujillo Meadows which is just north of Chama NM.
There are 50 sites and maybe 10 were occupied on a Saturday. It felt like we were boondocking in the wilderness but with the amenities of a natl forest campground (water available and pit toilets, no electricity or water at the sites). It's about 2 miles of dirt road, but good quality and no problem for an Escape.
It's first come first serve, but I can't imagine that all sites are ever full.
