Middle Island Country Club's Oak Tree and Spruce nines form part of a 27-hole facility located in central Suffolk County on Long Island, roughly sixty miles east of Manhattan. The course was designed by Baier Lustgarten, a regional architectural firm active in the mid-to-late twentieth century that produced several layouts across the New York metropolitan area. The property sits in a transitional zone between Long Island's more densely developed western communities and the agricultural and wooded landscapes of the East End. The terrain reflects the glacial topography characteristic of Long Island's interior, with gentle rolling land shaped by the terminal moraine. The routing likely moves through a mix of mature tree corridors and more open fairway corridors, with the native vegetation including oak, pine, and spruce that give the nines their names. Water features and bunker complexes provide strategic interest, though the overall character tends toward parkland golf rather than links-style play. Middle Island Country Club operates as a private facility serving the surrounding residential communities of central Suffolk County. The club provides a traditional country club experience with golf as the centerpiece, complemented by social and dining amenities typical of Long Island's suburban club culture. The 27-hole configuration allows for varied routing combinations and flexible tee sheet management, a practical design approach common among clubs built during periods of membership growth in the region.
