Alamosa National Wildlife Refuge

Alamosa National Wildlife Refuge is a protected area along the Rio Grande in southern Colorado with extensive wetlands and river floodplains. The refuge provides habitat for hundreds of bird species, including migratory birds, raptors, and waterfowl that benefit from the diverse vegetation and water habitats.

The refuge was founded in 1962 by the United States Fish and Wildlife Service to protect migratory birds during their journeys. This decision helped preserve the wetlands and continues to ensure that this section of the river provides functioning habitats for wildlife today.

The name comes from the Alamosa River that flows through the area and shapes the landscape. Visitors can watch the behavior of migratory birds, especially during spring and fall when thousands of cranes fill the valley.

The area is open from one hour before sunrise until one hour after sunset, which matches the natural rhythm of the birds. The main entrance is located at El Rancho Lane near Highway 160, and the grounds offer walking paths and driving routes for exploring.

During spring and fall migration, up to 20,000 cranes gather here forming one of the largest concentrations of this species in North America. This temporary gathering attracts many nature watchers and photographers who want to witness this remarkable natural event.
