The South Course at Los Serranos Golf & Country Club occupies rolling terrain in Chino Hills, a community in the Pomona Valley foothills of Southern California. Designed by William Eaton and opened in the 1960s, the course reflects the era's approach to public-accessible golf in the region, with routing that works across natural elevation changes and takes advantage of views toward the surrounding hills. The property sits in an area that transitioned from ranch land to suburban development during the postwar decades, and the course retains a sense of openness characteristic of inland Southern California layouts. The South Course plays as the companion to Los Serranos' North Course, and the two share the facility's practice areas and clubhouse. The design incorporates the site's natural contours, with fairways that move through valleys and across hillsides. Mature trees frame many holes, and several greens are elevated or positioned to require approach shots that account for the terrain. Water features appear on a handful of holes, adding variety to the strategic demands. Los Serranos operates as a semi-private facility, hosting both member and public play. The club serves the Inland Empire golf community and has been a venue for regional amateur competitions and junior golf programs over the decades. The South Course offers a straightforward test suited to a range of skill levels, with length and elevation providing the primary challenges.
