Costilla County was the first area of the state of Colorado to be colonized, with recorded history dating back to 1540, the year Coronado explored the Southwest.
Costilla County has 3 towns and several smaller communities.
Smaller communities include Chama, San Pedro, Los Fuertes, Garcia, Jaroso, San Francisco, San Acacio, and Mesita. All were established shortly after the town of San Luis in 1851, according to the Costilla County site.
San Luis: San Luis, the oldest town in Colorado, is the county seat. Visit the San de Cristo Heritage Center, Stations of the Cross Shrine, La Capilla de Todas los Santos, the Sangre de Cristo Parish Hall, and the R & R Supermarket (the oldest business in Colorado).
Fort Garland: Fort Garland, the eastern gateway to the San Luis Valley, is home to Fort Garland Museum. The fort was established in 1858 and was commanded by Christopher “Kit” Carson at one time.
Blanca: Blanca is named for Blanca Peak which soars to 14,345 ft. It was founded in 1908 following a land lottery and was incorporated in 1909.
