A ten mile out and back in Brentwood. This trail parallels all the other north-south fire roads in Topanga State Park and I had wondered about it for some time. It’s not listed in any guidebook as far as I know, and is located just beyond the border of my Tom Harrison map. I could see this fire road from Westridge Fire Road and even passed the upper trailhead while hiking on Dirt Mulholland. Recently I stumbled upon an online review and figured it was referring to my mystery trail. If you’ve hiked the other fire roads in the area then you’ll find it’s very similar only less crowded, both good things.
