El Prieto is definitely one of the best single track experiences in Southern California. Extreme exposure, tight switch backs, fun turns, stream crossings, and rock gardens all within a ~2 mile descent through a oak lined canyon. This is classic mountain biking with a challenge for everyone.

Beginning riders may walk many of the technical sections but the trail is definitely rideable from beginning to end by experienced riders. Beware of poison oak along this trail as its pretty much around all year.

El Prieto is generally accessed by climbing up Brown Mountain to the first saddle and then descending the Fern Truck Trail to the upper El Prieto entrance. As you ascend Brown, you will see the downhill exit of El Prieto at the log. Do be aware that plenty of hikers visit El Prieto and using a bell is highly advised, especially on weekends.

Access Info

Park at the parking lot overlooking JPL or in the upper neighborhoods if you’re leery of your car getting broken into during less crowded hours.
