Come Prepared

Remember that when you visit the refuge you are in a desert environment. Come prepared and be sure to take certain precautions.


  • It is suggested that visitors bring plenty of water, snacks, a map, sunscreen, and other necessary equipment when hiking or auto-touring.  
  • Maps are available in the Public Use and Hunting Regulations leaflet located at the entrances to the refuge.  
  • Four-wheel drive is recommended on many of the roads. 
  • Vehicles must remain within 100 feet of designated roads.  
  • There is limited to no cell phone service on the refuge. 
  • Visitors are encouraged to explore the refuge, excluding private inholdings and the area closed for the protection of Sonoran pronghorn. 
  • Entry of mines is prohibited for public safety and to avoid the spread of the devastating white-nose syndrome, a deadly fungus that is devastating to the bat population. 
  • During World War II, General Patton conducted military training exercises here. As a result, unexploded ordnance may occasionally be encountered during cross-country hiking. These items should never be picked up, but instead should be immediately reported to the refuge. If possible, please provide GPS coordinates.
