Costilla County

Costilla County is an administrative county in south-central Colorado that spans valleys and mountain ranges. San Luis serves as the county seat and provides local government services to residents.

The county was established on November 1, 1861, making it one of the original seventeen counties formed in the Colorado region. This early founding shaped its development and settlement patterns.

The county preserves strong Hispanic traditions through local festivals and traditional agricultural practices passed down through generations. These customs shape community life and gatherings to this day.

Visitors can explore the county via roads that run through valleys and over mountain passes with various viewpoints. The best way to experience the area is by driving slowly and making stops at places of interest.

The region preserves first-water rights dating back to 1851 through the San Luis People's Ditch irrigation system. This historical system shows how early settlers organized water access for farming.
