Western Hills Golf & Country Club sits in Chino Hills, a city in the Puente Hills region of southwestern San Bernardino County. The course was designed by Harry Rainville and David Rainville, a father-son architectural team that worked primarily in Southern California during the latter half of the twentieth century. The Rainvilles designed and remodeled numerous courses across the region, typically creating layouts suited to the rolling terrain characteristic of inland Southern California. The course occupies land that features the moderate elevation changes common to the Puente Hills area. This topography allows for varied hole corridors and strategic interest derived from uphill, downhill, and sidehill lies. The routing takes advantage of natural landforms while incorporating the mature landscaping that has developed over the decades since the course opened. Western Hills serves as a private country club facility with both golf and social amenities typical of established Southern California clubs from its era. The membership draws from the surrounding communities of Chino Hills and neighboring cities in the eastern Los Angeles County and western San Bernardino County corridor. The club provides a traditional country club experience centered on golf, with the course remaining the primary recreational focus for members and their guests throughout the year in the region's Mediterranean climate.
