Pretty good but brush gets tight in some spots. Lots of poison oak on the edges to be aware of that. Only 2 or 3 little wash out that should probably be walked for safety. Whole trail is passable and mostly good condition

Rode up and down on 2/10/2026. The trail is well maintained near the bottom. Beginning a couple miles in, there are some features that will require most riders to dismount. The top two miles of trail are rarely traveled and more like a goat trail. There is currently a crew doing trail maintenance, so conditions should be expected to improve.

Poodle-dog brush cleared back. 5 downed trees across the trail, but easy to get over them. Narrow and loose as always.
