The entrance to the trail can be hard to spot so you you'll want to be on the lookout for a right-hand turn going uphill off the main loop by looking for a right turn at the intersection with Raydar Love
(which would be left). As you continue ascending, you'll want to keep left, as there's an even lower secret trail that will take you way off course.
You can also access the trail at the top near the entrance to Upper Plumbers Crack
. Be on the lookout for the entrance which you can find off to your right near the end of the first big ridge descent.
