Telegraph Canyon Trail stands out as one of the signature routes within Chino Hills State Park, frequently highlighted by Modern Hiker and the Chino Hills State Park interpretive staff. The trail traverses grassy meadows and wooded corridors, offering chances to spot mule deer and native birds. Its moderate length and varied terrain make it a favorite for those seeking a half-day adventure with a real sense of immersion in the Inland Empire’s natural landscape. The park’s official website confirms the trail’s open status and ongoing maintenance.
