Diamond Bar, CA Area Guide

Long before Diamond Bar became a suburb, the land was known as Rancho Los Nogales, a Mexican land grant awarded to Jose de la Luz Linares in 1840 by Governor Juan Alvarado. Walnut groves and cattle ranching defined the property for decades, and a diamond-shaped cattle brand used by a later ranch owner gave the city its name.

The shift from ranchland to suburb happened in the 1960s, when developers platted the area as a planned bedroom community. Diamond Bar incorporated as a city in 1989, a milestone celebrated every April with a City Birthday Party. A historic windmill near a local shopping center stands as the lone physical reminder of that agrarian past, lit each December during a community ceremony.

Dining in Diamond Bar spans a wide range of cuisines, with Vietnamese, Indian, and Chinese restaurants making up a large share of local options. Diamond Bar Town Center holds the densest cluster of eateries, while Diamond Hills Plaza on the south side offers an international food court anchored by Super H Mart. Every autumn, a local Restaurant Week brings discounts and promotions across participating spots -- a good time to work through the breadth of the dining scene.

Getting around Diamond Bar means relying on a car for most daily trips, as the city's suburban street network was built around driving. State Route 60 connects residents west toward downtown Los Angeles, roughly 30 miles away, and east toward Riverside at a similar distance. SR-57 provides additional access toward Orange County.

For rail commuters, the Industry Metrolink Station sits less than three miles away and connects to LA Union Station. Foothill Transit buses run along Diamond Bar Boulevard for those who prefer not to drive. Ontario International Airport is approximately 15 miles east, and the Pomona Amtrak station is about seven miles away for longer regional trips.

Sycamore Canyon Park covers 50 acres on the western edge of the city, where a trail follows a stream and staircases wind through canyon terrain, making it the largest green space within Diamond Bar's boundaries. Across town, Pantera Park offers more than 20 acres of ballfields, soccer fields, basketball courts, a dog park, and a hiking trail with panoramic overlooks. Each December, Pantera Park transforms for the Winter Snow Fest, when 100 tons of snow arrive for community sledding and other winter fun.

The Summitridge Park Trail System links several city parks through a network of hilly paths, rewarding hikers with views of the San Gabriel Mountains, the Santa Ana Mountains, and the downtown Los Angeles skyline. Summitridge Park also hosts outdoor concerts and movies in June. For more expansive recreation, Frank G. Bonelli Regional Park and Schabarum Regional Park are both within roughly ten miles, and the public Diamond Bar Golf Course offers an 18-hole round without leaving the city.

Rents in Diamond Bar run above the California state average for comparable unit sizes, with one-bedroom apartments averaging around $2,460 per month and two-bedroom units averaging near $2,775. Three-bedroom apartments average close to $2,953 per month. Year-over-year changes have been essentially flat across all unit sizes.

Several shopping centers anchor the retail landscape across Diamond Bar's neighborhoods. Diamond Bar Town Center, centrally located, is the largest commercial destination with grocery and restaurant anchors, while Diamond Hills Plaza on the south end draws shoppers with its international grocery focus. On the northern side of town, Diamond Bar Village, Diamond Bar Plaza, Towne Centre Village, and Sunset Village provide additional options within a short drive of the city center.

A strong calendar of community events and a trail system with sweeping views of the San Gabriel Mountains make Diamond Bar a distinctive corner of eastern LA County. The city's dining scene, public golf course, and proximity to both Cal Poly Pomona and Mt. San Antonio College round out a well-connected suburban setting.
