Santa Anita Ridge

This is a great training trip for hikers who want to increase their endurance when it comes to distance and elevation gain.  Veterans might find this long trip on a fire road a little monotonous (although the views of the San Gabriel Valley are great), but if you are yet to do a hike with, say, over 1,000 feet of elevation gain or a 5 mile distance, this is a great place to start.

From Chantry Flats, the San Olene Fire Road heads west along the Santa Anita Ridge, with panoramic views of the Los Angeles basin (especially the nearby race track).  While it misses out on the seclusion of the hikes lower in Santa Anita Canyon, such as the Sturtevant Falls trail, the wide vistas are hard to beat.  On clear days, you can expect to see the ocean, the Santa Ana Mountains and the higher, eastern peaks of the San Gabriels.

You leave the parking lot via the paved service road (the same road that marks the last stretch of the Winter Creek and Mount Zion loops).  After a short uphill climb, stay on the road where the Upper Winter Creek trail branches off to the right.  You soon pass by a heliport and you continue your climb.

After three miles of steady ascent, the road passes through a pleasant wooded area, and about half a mile later, you arrive at a flat area where there are great views of the nearby communities.  Sunsets are particularly nice here, and with easy navigation and terrain, this trip works well as an evening hike.  Just remember that the Chantry Flats gate is closed nightly at 8pm.



  1. Thanks for posting this. It’s an alternative I haven’t tried, yet. Never knew that the road itself could make a trail–I always cut off at the Upper Winter Creek trail.

    One correction–the Chantry Flats gate is supposed to be locked at 8pm, not 10pm. I don’t know how prompt they are about locking it, but that’s what the sign at the bottom of the road says.
