sitting on the start of the hill if you look to your right, that ridgeline is where the trail loops back to finish. the trail is marked with green paint on the rocks. there are a few bail out point that you can cut the distance down as well.
Review: First time on this trail and I have to say it was a blast. Either I didn't see the trail markers or they are sporadically painted on the rocks, so we ended up just winging it and had a great time, definitely coming back.
