The 18-hole South Course, originally crafted by Scottish-American architect Tom Bendelow in 1915 and reconfigured with contributions from Willie Watson and modern enhancements by Steve Smyers in 2008, plays to 7,267 yards from the tips at par 72 (rating 72.3, slope 132) on expansive, tree-lined terrain featuring Butterfield Creek as a recurring hazard. This underrated layout offers a more forgiving yet strategic alternative to its sibling, with large undulating bentgrass greens, isolated holes for varied play, and a focus on recovery shots, earning top-10 status in Illinois while complementing the club's historic prestige.
