Exploring the Pueblo Alta trail on the mesa at Chaco Canyon leads you to a wonderful ruin sitting lonely on the crest of a hill. Pueblo Alto Ruins are the highest ruins in the park and don’t have the pressure of tourists as the others because you have to climb a winding trail up the canyon walls then a couple mile stretch of the legs to the ruins but it is well worth the trip. I made it there in the early afternoon on a beautiful fall day just before Thanksgiving.
