The Puente Hills lie to the south of the San Gabriel Valley and the Pomona Freeway (State Route 60), to the east of the San Gabriel River Freeway (Interstate 605), to the north of Whittier Boulevard, and to the west of the city of Diamond Bar and Chino Hills. Cities to its north are the City of Industry, Hacienda Heights, and Rowland Heights. To the south are Whittier, La Habra Heights, and Brea. The Brea-Olinda Oil Field, discovered in 1880 and still producing in 2014, is in the southernmost portion of the hills adjacent to the city of Brea.
The Puente Hills are in the California chaparral and woodlands ecoregion of the California Floristic Province. The remnant California native plants here are in the chaparral and oak woodland plant communities, with stands of California native grasses. Vascular Plants of the Whittier Hills, a floristic study, was completed by Julie A. Schneider Ljubenkov and Timothy S. Ross (2001), and published in Crossosoma. It built on the work of Bob Muns.
Rio Hondo College is located at the foot of the western end of the hills, and the Puente Hills Landfill is nearby. Rose Hills Memorial Park occupies portions of the northern area. The highest point in the western hills is Workman Hill, named for the pioneer Workman family. The Puente Hills Mall is located north of the hills. Hsi Lai Temple in Hacienda Heights, the second largest Buddhist temple and monastery in the western hemisphere, is located in the hills.
In the scene from Back to the Future (1985 film), Doc Brown introduces the iconic Delorean time machine in the parking lot of Puente Hills Mall.

A commercial discovery was made in 1897, for what would become the Whittier Oil Field, when a well was drilled to a depth of 984 feet. The location was in the central area of production. By 1903, about 100 wells were in operation and by 1924, 163 commercial wells were in operation.
There has been a long history of oil drilling in the Puente Hills. In the early 20th century, several companies drilled, including Simon Murphy's Murphy Oil Company. Recently, Matrix Oil has proposed resumption of oil drilling on several acres in the Puente Hills.
