Cog Hill is located just SW of Chicago along highway 171 in Lemont with 4-18 hole championship level layouts with #2 & #4 acknowledged as the favored layouts.

Dubsdread #4 is a shot-maker's, parkland layout with narrow, tree lined landing areas, a plethora of sand bunkers positioned both along the fairways and greens, multiple water hazards, and large, undulating greens. It was once the venue for the PGA's Western Open for a number of years, and originally designed by Dick Wilson and Joe Lee, but redesigned by the "Open Doctor" Rees Jones in 2008. There's six sets of tees overall from 5,441 yards to 7,554 yards, the white tees play to 6,382 yards, 71.9/134, course/slope ratings.

The #2 Ravines' is appropriately titled as over half the holes cross ravines along tree lined fairways over rolling terrain with numerous water hazards, sand bunkers, and small, quick and undulating greens. There's four sets of tees overall, the tips play to 6,837 yards, 72.7/126, course/slope, originally designed by David McIntosh & Bert Coghill in 1929 with later redesign work by Joe Lee & Rocky Roquemore.

The other courses, #1, a David McIntosh original design from 1927, with a 1963 Dick Wilson redesign, and #3, a Dick Wilson design are both routed over similar terrain and are parkland style layouts as well and more of a value than #s 2 or 4.
