Paramount Ranch is located in Agoura off of Cornell Road, between Kanan Road and Mulholland. Click here for a map in a pdf file on the National Park Service website.
Paramount Pictures originally purchased 2,700 acres here for use as a "movie ranch" in 1927 and since then, hundreds of movies and TV shows have been filmed there. A permanent western town was built there in the early 1950s using old Paramount Pictures props. You can walk freely around the buildings (but you can't walk inside them). This is a site to behold for any fans of old movies.
A list of movies filmed at Paramount Ranch is here. These include films like The Last Outlaw (Gary Cooper), The Virginian (Gary Cooper), Tom Sawyer, Huckleberry Finn (Jackie Coogan), Million Dollar Legs (W.C. Fields), Adventures of Marco Polo, Remember the Night (Barbara Stanwyck) and many more. From 1992 to 1997, the TV show, Dr. Quinn, Medicine Woman (featuring Jane Seymour) was filmed there.
In addition to the western town, there are restrooms, picnic areas and plenty of hiking trails at the park. Please be very careful around the set as these are one of a kind and very old. More information at www.nps.gov/samo/planyourvisit/paramountranch.htm or call the NPS at 805.370.2301.
