Butterfield Stage is one of two eighteen-hole courses at El Prado Golf Courses, a municipal facility in Chino, California. The course was designed by Harry Rainville and his son David Rainville, a father-son team known for their work on accessible public layouts throughout Southern California during the latter decades of the twentieth century. The Rainvilles typically created straightforward designs suited to everyday play, and Butterfield Stage reflects that practical approach with routing that accommodates golfers of varying skill levels. The course occupies relatively flat terrain characteristic of the Chino Valley, an inland area east of Los Angeles where agricultural land has gradually given way to residential and recreational development. Tree-lined fairways and water features provide definition and strategic interest on a site that lacks significant natural elevation change. The layout relies on bunkering, mature landscaping, and hazard placement to create variety and challenge rather than dramatic topography. El Prado serves as a busy public facility for the Inland Empire region, offering accessible golf in an area where municipal courses provide important recreational opportunities for a broad demographic. Butterfield Stage and its companion course, Chino Creek, share practice facilities and a clubhouse that supports steady daily play. The course functions primarily as a community amenity, hosting local tournaments and league play while maintaining conditions suitable for regular public rounds throughout the year.
