Diamond Bar Golf Course

The inspiration

When freeway improvements to State Routes 57 and 60 required about ten acres of the property, Los Angeles County chose not to simply close the course but to rethink and upgrade the whole layout¹ . The county-owned public course reopened in April 2024 with redesigned greens and bunkers, new irrigation, and a fresh practice area, keeping its full 6,801-yard length^2,1 . It sits at the corner of three Southern California counties, making it a convenient escape from city life for golfers from Los Angeles, Orange County and the Inland Empire³ .

Who's behind it

The original course was designed by William F Bell, one of the twentieth century's most prolific golf architects, and opened in 1963^3,1 . Local course architect Casey O'Callaghan led the 2024 renovation, rebuilding every tee, bunker and green while keeping the same par and yardage^1,4 . The county's Department of Parks and Recreation administers the facility, with American Golf Corporation running operations under a long-term lease² .

What to order

• The par-3s: O'Callaghan gave each one a different look, so no two play the same way .¹
• Hole 3: the course's own site calls it a scenic signature hole with mountain views .³
• Hole 11: a challenging test, according to the course's own description .³
• Practice time before the round: a driving range with night lighting, a putting green, chipping area and practice bunkers .³

What people are saying

Locals and regulars who play the course say it is better than ever after the renovation, and community residents wandered by during the closure to track the progress¹ . General Manager Mark Kuramoto has noted heavy demand for tee times since reopening, along with returning golfers eager to see the changes¹ . Kuramoto also says non-golf traffic is up thanks to a revised restaurant menu, with families and local workers coming in to eat¹ .
