The trail is briones to my Diablo between the gate at the top of borges ranch all the way to dusty road gate near the wall point trail. Condition was atrocious.

The County does not maintain the trails on Mt. Diablo. This trail is maintained by EBRPD. Here is the website with information about the trail as well as contact information. https://www.ebparks.org/parks/trails/briones_mtdiablo/default.htm

Thanks
