A stunningly beautiful 5,500-acre parkland in the Simi Hills nestled at the western edge of the San Fernando Valley, Upper Las Virgenes Open Space Preserve was once slated to be a mega-development known as Ahmanson Ranch. The huge parkland offers rolling hills studded with valley oaks, sycamore-lined canyon bottoms, miles of trails, and vistas of unspoiled California landscapes.
Access to the park is at the Victory Trailhead at the western terminus of Victory Boulevard in West Hills, at the Upper Las Virgenes Canyon Trailhead at the northern end of Las Virgenes Canyon Road in Calabasas, and through trails headed east on the National Park Service land at Cheesebro Canyon. The trails are open to hikers, mountain bikers, and equestrians during daylight hours. No unauthorized motorized vehicles are allowed.
