TheSan Luis Mountains are a small, lower elevation mountain range of central-southernPima County Arizona adjacent to theU.S.-Mexico border, northeast ofSasabe, Arizona–Sasabe, Sonora.
The range is northwest-southeast trending, about 10 miles (16 km) in length.[2][3] The range borders theBuenos Aires National Wildlife Refuge to the west; both are in the southeast of theAltar Valley. The southeast of the range abutsCobre Ridge, with various peaks, and Cobre Ridge borders the western edge of thePajarito Wilderness, at the west end of thePajarito Mountains.
The community ofArivaca lies in the valley northeast of the San Luis Mountains at the southeast end of theLas Guijas Mountains;Arivaca Lake lies about 5 mi upstream on Arivaca Wash. The International Border lies less than one mile south of the southern margin of the range in Fresnal Wash. Cumero Mountain Peak at 4,698 feet (1,432 m) is 2.1 miles (3.4 km) north of the border.[2][3]
Two mountain ranges, the San Luis in the southwest, and theCerro Colorado Mountains northwest lie west of the four-mountain sequence of theTumacacori Highlands (of adjacent westernSanta Cruz County) of theTumacacori,Atascosa, Pajarito, and theSierra La Esmeralda mountain ranges. The Highlands are now part of aconservancy study of wild cat 'travel corridor' usage between mountains, the study calledCuatros Gatos (Four Cats), for themountain lions,bobcat,ocelot, andjaguar.[4]
