A little on the
Chama Area.
There is much to see & do in the
Santa Fe & Bandelier Nat'l Mon't area of New Mexico -A Trip Report last summer.
Bandelier Nat'l Mon't is off US 285. We were there in August last year. Not too hot at all. Cools off quickly after sundown each evening. I believe we were there years ago in July. Warmer during the day, but cool nights.
Los Alamos is a very neat small city in itself. Free bus system with very neat buses. Very pretty setting up in the high country. Somewhat of a gated community as well. We only drove through & stopped at a SuperMarket. A nice town.

I'd take US 160 E. to Pagosa Springs US 84 S. to Chama & on to Santa Fe as well. Good road somethings to see along it as well.
Two neat stops, north of Abiquiu, worth a see would be the Echo Amphitheater, a Natural rock formation, and the Ghost Ranch Piedra Lumbre Education and Visitor Center, located on U.S. Highway 84 just one mile north of the main Ghost Ranch entrance, has exhibits and a gift shop. A very nice museum in "O´Keefe Country." The Echo Amphitheater is past the visitor center some miles.
US 550 would be more for going to ABQ.
