Hacienda Hills Trail Professional Guide
Detailed Trail Description from our Guidebook
"This dirt-path loop is a gradual climb through cool forest and sunbaked switchbacks to 1,000-foot elevation and views of downtown Los Angeles, the coastal plains of Orange County, and the wooded community of La Habra Heights.
The Hacienda Hills Trail is part of the Skyline Trail in the Puente–Chino Hills Wildlife Corridor, an unbroken chain of plant and wildlife habitat that extends about 30 miles from the Cleveland National Forest in Orange County to the west end of the Puente Hills in Los Angeles County. According to the Sierra Club, the area represents one of the largest intact native habitats in the urban Los Angeles basin. It is maintained by the Puente Hills Landfill Native Habitat Authority—a collaborative effort of Los Angeles County, the city of Whittier, and the Sanitation Districts of Los Angeles—which was created in 1984 to mitigate the effects of the nearby Puente Hills Landfill. The majority of hikers here seem to be residents of the Hacienda Heights area out for weekend exercise jaunts, but it never seems over-crowded. Dogs are allowed, and mountain bikes are permitted in parts of the preserve."
