Hacienda Hills: Ahwinga, Native Oak, Schabarum Trails Professional Review and Guide
"For more than 25 years, the Seventh Avenue Trailhead, as it was known, provided access (and little else) to the Puente Hills trail system. In 2005, vast improvements were made, and this key entryway renamed the Hacienda Hills Trailhead. Trailhead improvements include better parking, restrooms, native plant landscaping, interpretive panels, wrought iron entry gates that are works of art, and improved trail signage. Some fine hiking trails were constructed to link with the pre-existing dirt service roads built by ranchers and oil companies. Hacienda Hills Trailhead is the gateway to a 225-acre reserve set aside as a mitigation measure after an approved expansion of the nearby mega-landfill. The considerable conservation successes that have occurred in the Puente Hills have been funded by the Puente Hills Landfill Native Habitat Preservation Authority, which collects “tipping fees” from the Puente Hills Landfill, the largest landfill in the U.S. Created in 1994, this agency has purchased Powder Canyon, Sycamore Canyon and other key parcels in the hills."
