East Ridge Trail to West Ridge Trail Loop
This is a great run with both flat wide fire roads and single track trails. It works great in either direction.
The top part is along the ridge trail, which is a fairly flat and easy job. Take the second trail head down (not French - though that works too). This is the the most technical part of the run, because the trail is smaller and less well maintained. As you get to the bottom, the trail becomes wider, flatter, and follows a stream through a redwood grove. Take Prince trail back to the top to complete the run on the other side of the ridge trail.
