Michael D. Antonovich Regional Park at Joughin Ranch



2,326-acre Michael D. Antonovich Regional Park at Joughin Ranch is located on the southern slopes of the Santa Susana Mountains between Chatsworth and Simi Valley. The park offers stunning vistas, rolling hills, oak and walnut woodland, water sources, and an abundance of wildlife. Throughout the park, majestic views of the San Fernando Valley; the Santa Monica, Totopa, and Santa Susana Mountains; and the Simi Hills abound..

Part of a key watershed area for the Los Angeles River, the Antonovich Park encompasses the Headwaters of Devil, Ybarra, and Browns Canyons. These canyons contain extensive oak and walnut woodland and riparian corridors with year-round surface water.The rolling topography of the park includes grasslands, chaparral and woodlands of oak, ash, walnut, sycamore and some big-cone Douglas fir. Several threatened plant species, such as the slender mariposalily and the Santa Susana tarplant, are found in and around the park. The surrounding area provides optimal foraging and nesting habitat for many raptors, including golden eagles, great horned owls, northern harriers and red-tailed, prairie and Copper’s hawks. The wilderness area abuts Rocky Peak Park, a 4,815-acre wilderness park to the west. An extensive dirt road system within the park connects the Marge Feinberg Rim of the Valley Trail and lower Browns Canyon for hiking, mountain biking and equestrian use.
