About Costilla County Fair
The Costilla County Fair in San Luis celebrates the oldest continuously occupied town in Colorado — San Luis was settled in 1851 by Hispanic families from New Mexico under the Sangre de Cristo Land Grant, and the community's acequia irrigation system (the oldest still-operating water rights in Colorado), the Stations of the Cross sculpture trail, and the bison commons heritage define a town of extraordinary cultural depth.
What to Expect
Expect livestock shows, 4-H competitions, San Luis Valley potato and agricultural exhibits, Hispanic cultural food and craft vendors, and a fair honoring the deep Spanish colonial heritage of Colorado's oldest town.
Visitor Tips
San Luis's Stations of the Cross sculpture trail on a hilltop above town is one of Colorado's most moving public art installations. The Sangre de Cristo Heritage Center preserves the town's acequia irrigation heritage. The Trinchera Ranch and Taylor Ranch preserves provide glimpses of the original land grant landscape.
