The 18-hole championship golf course was completed in 1927 and has matured into one of the very finest in the area. At 6502 yards from the championship tees the par 72 course is both challenging and enjoyable for golfers of all skill levels.

PGA Touring Professionals Bob Goalby and his nephew Jay Haas both attribute some of their success in competitive golf to skills honed while playing and practicing on this interesting and often difficult venue.

The Jay Haas Practice Facility dedicated in 2004 includes a driving range and short game practice areas.
The Pro Shop, completed in 1989 and renovated in 2002 features a large retail area with an extensive selection of golf equipment, clothing and accessories. The courteous professional staff offers group and individual instruction as well as club fitting.
The Club's golf activities include a full schedule of tournaments and special events for men, ladies, couples, and juniors. In addition, St. Clair participates in many inter-club programs throughout the St. Louis area, with opportunities for regional competition for men, women, and juniors.
