The Estuary course at Grey Oaks Golf & Country Club is a Bob Cupp design that opened in the mid-1990s as part of this private residential community in Naples. Cupp, known for his work with Jack Nicklaus before establishing his own practice, created a layout that navigates the natural wetlands and preserve areas characteristic of southwest Florida's coastal plain. The routing takes advantage of the property's namesake estuarine environment, with holes playing alongside and across marshlands that connect to the nearby Gordon River system. The course features the elevated greens and strategic bunkering typical of Cupp's design philosophy, which emphasizes shot values and risk-reward decision-making. Water comes into play on multiple holes, though the design provides options for players who choose conservative lines. The native vegetation and preserve areas create defined corridors and frame many holes, while the relatively flat terrain is shaped through contouring and mounding to add visual interest and strategic variety. Grey Oaks operates as a private equity club with multiple courses on the property. The Estuary has historically served as one of the club's championship layouts, though it shares attention with the other courses designed by different architects. The club caters to a membership drawn largely from seasonal residents and retirees who appreciate the Southwest Florida lifestyle. The facility includes traditional country club amenities and dining options that complement the golf experience.
