San Luis Valley Fair Overview

In Alamosa, the San Luis Valley Fair serves the unique high-altitude agricultural valley of southern Colorado — a high desert basin at 7,500 feet elevation that produces exceptional potatoes, barley, and livestock under extreme growing conditions. The San Luis Valley is one of Colorado's most culturally distinctive regions, with deep Hispanic roots dating to Spanish colonial exploration.
