San Ignacio Golf Club's South Course is an Arthur Hills design located in Green Valley, Arizona, approximately thirty miles south of Tucson in the Santa Cruz Valley. Hills, known for his strategic bunkering and ability to work with varied terrain, routed this course through the high Sonoran Desert landscape characteristic of southern Arizona. The layout takes advantage of natural elevation changes and arroyos, with fairways framed by native vegetation including saguaro cacti, palo verde, mesquite, and ocotillo. The course reflects Hills's design philosophy of offering multiple playing angles and rewarding thoughtful course management over pure distance. Greens typically feature subtle contours, and the bunkering serves both strategic and visual purposes against the desert backdrop. Water comes into play on select holes, though the routing primarily emphasizes the natural desert character of the property. Views extend toward the surrounding mountain ranges that define this section of southern Arizona. Green Valley developed as a retirement and resort community beginning in the 1960s, and San Ignacio serves both residents and visitors seeking desert golf in a less congested setting than metropolitan Tucson. The club operates as part of the broader Green Valley recreational infrastructure, offering a more relaxed atmosphere than many of Arizona's higher-profile resort destinations. The South Course provides a representative example of desert golf design from the period when Hills was actively working throughout the American Southwest.
