The 92,000-acre Baca National Wildlife Refuge contains shrub lands, grasslands, wet meadows, playa wetlands, and riparian corridors. The refuge is a haven for migratory birds and resident wildlife. It is important in protecting the wildlife, habitat, and water of the northern San Luis Valley.
The refuge also contains archaeological evidence of more than 12,000 years of use by human beings, including the historic Luis Maria Baca Ranch.
The Baca Refuge is currently open to hunters and seasonal tours. Efforts to increase visitor access are ongoing.
