Visit Us

National wildlife refuges offer us all a chance to unplug from the stresses of daily life and reconnect with our natural surroundings. With 803,418 acres of designated wilderness, Cabeza Prieta National Wildlife Refuge offers wonderful opportunities to explore the wild Sonoran Desert. As one of the largest wilderness areas in the contiguous United States, visitors can experience the rugged solitude of the Sonoran Desert wilderness. Nicknamed “The Green Desert”, the Sonoran Desert is the most biodiverse desert in the world and is home to at least 60 species of mammals, more than 350 bird species, 20 amphibians, some 100 reptiles, and about 30 species of native fish. In addition, more than 2,000 species of plants have been identified in the Sonoran Desert.

Let our staff and volunteers at the visitor center help you plan your visit! This is a great starting point for visitors to become more familiar with the Refuge and the wildlife that live here. Visitors can browse nature and wildlife exhibits, obtain maps and brochures, and view informative wildlife videos. There’s even a 3D topographic map from a bird’s eye view of the whole refuge!  


There is no charge to visit, but permits are required for all visitors. See more under rules and regulations


Restrooms are available at the refuge headquarters/visitor center. There are no restrooms, pit toilets or comfort stations located within the refuge.  

Visitor Tips

The best time to visit Cabeza Prieta National Wildlife Refuge is during late fall, early spring, or winter when desert temperatures are cooler. Wildlife can be spotted most often in the early morning or evening – this is especially true during the summertime when hot temperatures cause many animals to hunker down during the day.  


There are many ways to enjoy Cabeza Prieta National Wildlife Refuge including hiking, camping, hunting, photography, birdwatching, and wildlife observation. Birding opportunities are especially abundant in the spring and fall when migratory birds pass through the Refuge. For an overnight adventure, you’ll find primitive campsites along El Camino del Diablo and Christmas Pass.

Every second Saturday of each month, the refuge invites the public to drive their cars up to Child's mountain. 1,500 feet above the desert floor, this mountain offers incredible views of Cabeza Prieta NWR and Barry Goldwater Airforce Range. The next Child's Mountain tour will be September 9th, 2023
