05-01 Truchas Peaks ~ September.
At an elevation of about 13,100 ft., the Truchas Peaks—part of Northern New Mexico’s Sangre de Cristo mountain range—are the fourth, fifth, and sixth highest points in the state. By mid-September, aspens on the peaks’ upper slopes begin to change into their autumn colors. As the days pass, larger and larger areas become yellow, orange and gold. The high elevations usually receive the season’s first snow, while below, the village of Truchas enjoys pleasant days and beautiful views.
