The Muggins Mountain Wilderness is a 7,711-acre (31.21 km2) wilderness area in the U.S. state of Arizona. It is located approximately 38 miles (61 km) east of Yuma, Arizona in the Muggins Mountains and adjacent to the agricultural Dome Valley and Gila River. The wilderness area is made up of the highest peak in the southern section of Muggins Mountains, Klothos Temple at 1,666 feet (508 m). Muggins Peak is adjacent to the peak southeastwards, at 1,424 feet (434 m). Three deeply cut washes drain the southwest border of the wilderness, Twin Tanks Wash, Muggins Wash, and Morgan Wash. Muggins Wash is the access point to the wilderness, by way of County 7th Street.
