It took me about 5x on the Fully Loop without getting lost. The route is so confusing and there is no consistent signage. There are a few places where the trail ends on the street and you have to find your way to the continuation of the trail. There is one steep downhill section where the trail abruptly ends on the sidewalk. I think people get deceived on the Loop, thinking it's an easy ride, but unaware of several dangerous pinch points.

Don't get me wrong, despite it's drawbacks, I think it's a treasure for mountain bikers. It's a signature ride for SoCal. Everyone should ride it at least once.
