Rio Arriba County

Rio Arriba County was the ninth county originally created for the Territory of New Mexico in 1852. The county seat was initially sited at San Pedro de Charmita, and shortly afterwards at Los Luceros. In 1860, the seat was moved to Plaza del Alcalde.

Since 1880, Tierra Amarilla has been the county seat. The Battle of Embudo Pass took place in the southern part of the county during the American invasion in January 1847.

The county has a total area of 5,896 square miles, a population of approximately 40,040, and its northern border is the Colorado state line. It is the fifth largest county in NM by area. The highest point in the county is the summit of Truchas Peak at 13,102 feet. Española is one of the more populated cities in the county with a portion of the central and eastern section in Santa Fe County.

The county has an abundance of outdoor activities and points of interest including Abiquiu Lake, the Chama River (a tributary of the Rio Grande), the Jicarilla Apache Reservation, Puye Cliff Dwellings, and the Monastery of Christ in the Desert.
