Paramount Ranch is located within the Santa Monica Mountains National Recreation Area just south of Agoura Hills and north of Malibu. It consists of more than 2,700 acres and includes extensive hiking trails. In 1927, Paramount Pictures purchased 2,400 acres for use as a movie ranch. After World War II, Paramount sold the property, including 326 acres to Bill Hertz who turned the land into a western town. Over the next 25 years, hundreds of films were made on the property. Movies included John Wayne, Chuck Norris, Burt Lancaster, Cary Grant, Roy Rogers, and Lucille Ball. Gun Smoke, Have Gun Will Travel, and The Rifleman were all shot at Paramount Ranch.

The "MASH" filming location is a popular hiking destination. The western town still exists and is available for viewing by the public at no cost. The Paramount Ranch entry is at 2813 Cornell Road in Agoura.

Coyote Canyon Trail

Coyote Canyon Trail, at Paramount Ranch, is a popular scenic half-mile round-trip hike in the Santa Monica Mountains. The trail starts just to the west of the park's Western Town which is located south of Old Agoura and north of Malibu.

Medea Creek

Medea Creek is a small creek that originates in the Simi Hills north of Oak Park in Ventura County. The creek flows south through Medea Creek Natural Park in Oak Park and then south through Agoura Hills, past Chumash Park and then further south through Malibu Junction into unincorporated Agoura. It then flows south into Malibou Lake which is a man-made lake located in the Santa Monica Mountains near Paramount Ranch. Any overflow from Malibou Lake flows into Malibu Creek and eventually into Malibu Lagoon which is part of Santa Monica Bay and the Pacific Ocean. Malibou Lake is not spelled like the name of the creek and city.
