Chino Hills, Mountain range at Orange, Los Angeles, and San Bernardino counties border, California, US
Chino Hills is a mountain range spanning three California counties where Orange, Los Angeles, and San Bernardino meet. The terrain features chaparral shrubland and oak woodlands, with the highest point reaching about 1,600 feet (485 meters).
The Tongva and Gabrieliño Native Americans established seasonal camps throughout these hills before Spanish colonizers arrived in the 1700s. The landscape was then converted into grazing grounds for mission cattle herds.
The hills serve as a living wildlife corridor where deer, coyotes, and numerous bird species move freely between fragmented habitats. This passage allows animals to travel across the landscape despite surrounding urban development.
Carbon Canyon Road is the main paved passage through the range, providing access between different areas of Southern California. This route offers the most direct way to traverse the hills without requiring unpaved roads or hiking trails.
A 5.4 magnitude earthquake originated here in 2008 and was felt across facilities throughout Southern California. This seismic event revealed the region's geological activity beneath the surface.
