The Little Harquahala Range borders the second valley and third mountain range, the McMullen Valley and Harquahala Mountains, on their southwest borders.

An even smaller range is connected north on the water divide, the 8-mile (13 km) long Granite Wash Mountains.

Granite Wash Pass is located at the northwest end of the mountains; Hope is west and Harcuvar, Arizona is east.

The Little Harquahala Mountains are on the northwest-by-southeast water divide between two washes.

The Bouse Wash flows northwest to the Colorado River; Centennial Wash (Maricopa County) is east and flows southeast to meet the Gila River at the "great Gila Bend", adjacent to the Gila Bend Mountains.
