Rio Grande County is located in the San Luis Valley of south-central Colorado, where wide-open agricultural lands meet dramatic mountain scenery. Del Norte serves as the county seat, while Monte Vista is the largest community.
The Rio Grande flows through the county and gives it its name. The Monte Vista National Wildlife Refuge is an important stop for migratory birds, especially sandhill cranes, while the Sangre de Cristo Mountains provide a striking backdrop to the valley.
U.S. Highway 160 crosses the county, connecting it with Alamosa and other communities across southern Colorado. With a population of around 12,000, Rio Grande County relies heavily on farming and ranching, with potato production being one of its best-known agricultural industries.
