Why you should experience MASH Production Location in Agoura Hills, California.
MASH Production Location is a cinematic canyon landscape where television history and the rugged terrain of the Santa Monica Mountains meet in one of Southern California's most recognizable filming sites.
Located within Malibu Creek State Park near Cornell Road on the western edge of Agoura Hills, the site rests in a broad valley framed by towering volcanic cliffs and open grasslands. The terrain feels expansive and quiet, with dusty trails winding through oak groves and along the banks of Malibu Creek. Standing here, it is easy to recognize why filmmakers chose this canyon to represent distant battlefields, the natural scenery already feels dramatic and remote.
What you didn't know about MASH Production Location.
MASH Production Location served as the outdoor filming set for the long-running television series MASH, one of the most influential shows in American television history.
When production began in the early 1970s, location scouts searched for a landscape that resembled the mountainous terrain of Korea where the story was set. Malibu Creek Canyon offered the perfect backdrop with its sweeping valley floor and rugged rock formations rising above the hills. The production crew built a full field hospital camp here, including tents, vehicles, and the now-famous signpost that pointed toward cities around the world. The location remained in use for the entire run of the series, appearing in hundreds of episodes and becoming permanently associated with the show's visual identity.
How to fold MASH Production Location into your trip.
MASH Production Location fits naturally into a scenic hike through Malibu Creek State Park when the day calls for both history and canyon landscapes.
Begin along the park's main trails where the path winds through open meadows and shaded oak groves before entering the dramatic canyon valley. As the trail approaches the filming site, the massive rock walls and wide clearing begin to resemble scenes familiar to longtime viewers of the series. Visitors often pause near the recreated signpost to reflect on the show's legacy or capture a photo before continuing along the trail. By the time the canyon opens back toward the park paths, the landscape leaves behind the rare feeling of standing inside a place where television history once came to life.
