Make the old M*A*S*H filming area your reason to pause, with the creek landscape as part of the day.
The day-use area off Las Virgenes Road is the arrival landmark. Follow the bicycle-permitted High Road and Crags Road corridor shown by the track toward the former M*A*S*H filming site. The park’s broader trail network includes walking routes that are not substitutes for this bike line. In particular, this guide does not add a Rock Pool hiking-trail shortcut.
This is a mountain-bike outing, even though the destination is familiar from television. Crags Road includes a narrow section mapped at about one metre wide, as well as rough or rocky ground. Changing grip and other trail users require control rather than speed. Walk a section whenever that is the better choice. Keep room for the return: time spent looking around the filming area comes in addition to the moving-time estimate.
Access depends on the creek crossing and current park conditions. State Parks reported the seasonal M*A*S*H bridge reinstalled in April 2026; that dated notice is not a promise for every future visit. Read the current park updates before travelling and turn back if the crossing is removed or closed. Bring water, check day-use entry arrangements and keep dogs out of the backcountry route.

The seasonal creek crossing is critical. Check the park notice before committing to the destination.

How to use this GPX
Download the file to your phone or bike computer.
Import it into a navigation app that accepts GPX tracks. Check the start, complete return and direction before leaving.
Save the app’s map for offline use if supported. The GPX file contains the track, not an offline street map.
Keep a way to get home. Signs, closures and your judgment take priority over the line on screen.
Shop approaches and walking detours are not included. This is a planned track, not a recorded or field-verified ride.
Turn at the last named waypoint and follow the mapped return. The downloaded track includes the return to the start.

Places along this ride.
1 researched places
Choose a permitted place completely off the riding line for your break. No exact on-track cafe has been verified for this new guide; bring your own drink and snack rather than depending on a business being open.
The former filming area in January 2010, with the old vehicle props and signpost. A destination overview for a pause off the through route; it does not show the seasonal creek crossing.
Pins identify researched places, not tested approaches or live opening status. Read the place guide before leaving the route. Photographs appear only when the place and reuse permission are established.

The ambulance remains and surrounding hills at the filming site in 2010. Archival props may change; do not depend on this photograph for current conditions.
High Road beside day-use parking — join the path at the mapped point. Street, parking and rental approaches are separate. The track returns here.
Bike choice
Use a suitable mountain bike, check brakes and tires, and be prepared to walk difficult sections.
Before leaving
Check current State Parks notices, especially the seasonal crossing. Never ford or bypass a closure to reach the filming site.
Leave some margin
Allow up to 180 minutes for the outing, plus travel and bike collection. This is a planning estimate, not a recorded ride time.
Water, facilities & a place to pause
Bring water, a snack, a charged phone and puncture supplies. No open cafe, working water fountain or available rental at the start is guaranteed by this guide. Check the official visitor information for facility hours.
Bring a suitable bike. A rental in the same area may not match this route or its start.
No. It is a planned track assembled from connected OpenStreetMap roads and bicycle-permitted paths. Each file is a full loop or an out-and-back, with named waypoints. We have not field-ridden it or checked same-day closures.
What is included in the distance?
The measured map geometry for one complete described outing, returning to the selected start. Rental-shop approaches, walking detours and extra laps are excluded. GPS devices may calculate a slightly different distance.
Can I use an e-bike?
These guides are for ordinary pedal bicycles. Check the exact bicycle class, local jurisdiction, park rules and posted signs; permissions differ by location and trail. An e-bike rental offer is not proof that a route allows it.
Does a route file prove the way is open?
No. Check the official access links on the guide before leaving. A closure, flood warning or posted restriction overrides the download; never bypass a barrier to follow a track.
What should I bring?
Water, sun protection, a helmet, a lock, a charged phone and the downloaded track. Check brakes and tire pressure. Allow extra time for collecting and returning a rental.
