This is a fun loop that involves climbing out toward West Hills to return with mostly downhill trails to get back to the trailhead at the end of Las Virgenes Rd. in Calabasas.

Need to Know

There is very little shade on this route. It is not extremely technical. There is no water or restrooms at start or on the trail.

Runner Notes

This route is almost all fire road. It is popular with hikers especially as you get towards the Victory Trailhead, so please be courteous to fellow trail users.


There is plenty of street parking at the end of Las Virgenes Rd. The trailhead is at the very end of the street. You start on a fire road, the Upper Las Viregenes Canyon Trail, that is mostly flat. You'll come to a T and will turn right to continue on the East Las Virgenes Canyon Trail. Continue on this trail, and you'll start a gradual climb towards the Victory Trailhead.

Here, you'll follow the Ahmanson Ranch House Trail. Pay attention because you'll need to stay right around mile three. If you stay straight, this will take you to the Victory Trailhead, so make the right turn and then immediate left as you continue to climb. We always like to take the short climb at around mile 3.3 to enjoy the beautiful views of the San Fernando Valley (not necessary but well worth it). Otherwise, stay on the Ahmanson Ranch House Trail.

You'll then make a right turn onto the Mary Weisbrock Loop Trail and then another right onto Crummer Ranch Road. It is pretty flat from the viewpoint until here, and at this point, you'll begin your descent back onto the Las Virgenes Canyon Trail. Enjoy the fun fire road descent because you have earned it.

At the end of Crummer Ranch Road, make a left on the East Las Virgenes Canyon Trail and continue until you get back to the T (watch for the signs so you don't miss the turn back to the parking area). Make a left onto Upper Las Viregenes Canyon Trail to head back to where you started.

Flora & Fauna

Diverse habitats and endangered species such as the California red-legged frog, the San Fernando Valley spineflower, and the Southwestern willow flycatcher are now permanently protected and can be found in the area.

This is during the summer. Springtime, this would all be green!

Beautiful sunrise just as you have finished your climb from the start. Just on the left, is the hill that is worth the climb for additional views.
