Course #1 Cog Hill's original course opened to the public in 1927.  The course is delicately routed through rolling, wooded terrain and provides a blend of playing lengths and difficulty to challenge golfers of all playing abilities.	Course #2-Ravines The "Ravines" course features a sporty, championship layout with tree-lined fairways, ravines, water hazards, and bunkers. The course was recognized alongside Course #4 as one of the "Ten Best Two-Course Combinations in the World."  Site of the 1997 U.S. Amateur Championship Qualifying.
Course #3 Though longer than Course #1, Course #3 features enough sand, woods, and water to test the accomplished player without punishing the beginner.	Course #4-Dubsdread Since opening in 1964, "Dubsdread" has been rated among the Top 100 golf courses in U.S. and host to numerous USGA and PGA Tour events, including the 2011 BMW Championship. In 2008, Rees Jones headed a renovation of this classic Dick Wilson design which places a premium on shot-making with heavily bunkered landing areas and undulating putting surfaces.
