What is a National Heritage Area?
A national heritage area is a region recognized by the United States Congress for its unique qualities and resources — natural, scenic, cultural, historic, and recreational.

Rich in history, religion, culture, and bio-diversity, the Sangre de Cristo National Heritage Area preserves a special place in our nation's history where the villages and lifestyles of some of America's earliest Spanish settlements still exist alongside newer railroad communities of the late 1800s.

You are entering the home of some of Colorado's earliest people. Prehistoric Clovis and Folsom people, as well as later indigenous tribal people, have hunted and gathered in this valley and surrounding mountains. Spanish explorers, Mexican settlers, fur traders, miners, American soldiers, and others have passed this way. The area was a true crossroads of cultures.

¡Bienvenidos al Valle de San Luis! Welcome!

The tracks of the Denver & Rio Grande Railroad, just to the south, first entered this area in the late 1870s, bringing industrialization and people from around the world. The earlier Hispanic settlers in the area joined together to adapt to new ways of life while holding tight to their own language, one that carries their unique culture.

3. Welcome to El Valle de San Luis Marker
Welcome “Caminante” — to Los Caminos Antiguos Scenic & Historic Byway and The Sangre de Cristo National Heritage Area
Looking north. This marker is the leftmost of two interpretive panels on the south side of the Los Caminos Antiguos Scenic & Historic Byway kiosk in Antonito. US Highway 285 is on the right.
National Heritage Area is a crossroads of the centuries. Here a unique blend of Native American, Hispano and Anglo settlement is reflected in the diversity of the people, art and traditions. The geographic isolation of our high desert valley and the peoples’ enduring ties to the land have given rise to a rich cultural heritage and ensured its preservation. Interwoven with the Valley’s natural history is a very long and rich human history. The San Luis Valley served prehistoric and Native American cultures as a seasonal hunting ground where fowl, game, and edible and medicinal plants were bountiful.
The San Luis Valley is a place where different peoples have converged for thousands of years. The Valley’s profound historical, religious, and cultural convergence remains visible in the landscape and can be experienced in its communities, art, food, lodging, and events.
