What I and others have been doing to work this trail into our ride is to go half way on south Abyss. Which happens to be about where the benches are. From there, hang a left out to the double track road and another left easteward on that road. Ride about 50 or 80 feet and you will see it on the right. Last I was there (2 weeks), the sign was not up yet so hopefully it will be easier to spot it. For now, where it ends you hang a left and you end up on east most side of the Abyss so you kind of start with the South Abyss again.
