Rapid, dramatic geologic changes created the spectacular landscape of Malibu Creek State Park. Its jagged mountains, rock outcroppings, cliff-like slopes and deep gorges were formed over two million years by severe climate changes, earthquakes, erosion and tectonic plate collisions. These forces continue to shape the landscape today. In the early days of the film industry, rugged terrain that could double for far-off locations was difficult to find near Hollywood. Filmmakers transformed this area into exotic locales such as old Mexico, outer space, and an army hospital in Korea. Movies and television shows filmed here include M*A*S*H, The Planet of the Apes, Pleasantville and How Green Was My Valley. The Angeles District Headquarters building here served as the “dream house” in the 1948 classic, Mr. Blandings Builds His Dream House. Just 25 miles from downtown Los Angeles, the park features hiking, fishing, bird watching and horseback riding opportunities. There are 15 miles of streamside trail through oak and sycamore woodlands on chaparral covered slopes. 23-mile Malibu Creek in the park is the principal watercourse of the Santa Monica Mountains, from Boney Mountain to Malibu Lagoon. The park is open from dawn until dusk. A visitor center is open on weekends only. The park is located four miles south of Highway 101 on Las Virgenes/Malibu Canyon Road.
