US Fish and Wildlife Service

Because of its many wetlands and strategic location for many unusual migratory birds, the San Luis Valley is home to three national wildlife refuges. Two are currently open to the public. The third, Baca National Wildlife Refuge, is not open to the public at this time; management planning is scheduled in coming years. Baca NWR was created in 2004 as part of the expansion of Great Sand Dunes National Monument into a national park and preserve, protecting the entire natural hydrological system of the Great Sand Dunes.

Alamosa NWR is located a few miles southeast of Alamosa, Colorado. It features wetlands along the Rio Grande River.

Monte Vista NWR is south of Monte Vista, Colorado. This refuge contains many restored or enhanced wetlands associated with agricultural lands. It is one of the hotspots in the valley to view thousands of sandhill cranes each spring and fall.
