This is one of the lost hikes of the Los Padres, the Trail head is a little hard to find. It can be found just past the old abandoned campground. Its a short two miles to the narrows which is spectacular. About quarter mile beyond that you will find running water. Fall colors were beautiful. Definitely worth the hike. The total distance you will travel from the closed road gate is about 8.5 miles round trip for this hike. I would rate as a moderate hike, terrain is easy to navigate.
Nice wide fire road with very little elevation gain. We did an out and back hike starting from the North end near the LA Department of water and power entrance. This would make a great Mtn bike ride.
Also added this trail to trailheadfinder.com, a much better user friendly site. You can get the gps track there without a paid membership.
