Sonoran Desert National Monument (SDNM) trail 8011A is an offshoot of 8011 going to the abandoned Altuda Mine. The deep fenced-off mine has tailing piles and remnants of a time gone by. The trail is easygoing and primarily gravel. The best camp spots are several flat areas near the mine.
Proceeding on SDNM 8011A past the “Unit 40A” gate requires a Barry M. Goldwater Range permit. Please refer to the permit required link above. The permit is only available online and requires viewing a mandatory safety video. A printed copy of your permit must be carried with you on this trail past the gate. SDNM 8011A runs through a very remote area of the Sonoran Desert. Please take all necessary precautions.
