Costilla County offers big-sky horizons, storied history, and room to breathe across the southern San Luis Valley. In the county seat of San Luis—the oldest continuously inhabited town in the state—you can climb the mesa to the Shrine of the Stations of the Cross or tour frontier-era adobe barracks at the Fort Garland Museum & Cultural Center. Communities like Fort Garland and Blanca anchor daily life with local eateries, outfitters, and seasonal events celebrating Hispano and Indigenous heritage.
Outdoors, the possibilities are wide open. Roll sand boards at Great Sand Dunes National Park & Preserve, cast for trout at high-desert reservoirs, or roam piñon-dotted foothills in the Rio Grande National Forest. Road trippers trace centuries of trade and migration along the Los Caminos Antiguos Scenic and Historic Byway, with sweeping views of the Sangre de Cristo range at every turn.
Families appreciate small, connected schools, including Centennial R-1 in San Luis and Sierra Grande R-30 in Blanca, where students find close-knit classrooms, athletics, and hands-on programs. For services, permitting, and local updates, the county’s official hub is the Costilla County government. Larger-city amenities, medical care, and university resources are a short drive away in Alamosa, home to Adams State University.
