Trip report
Jul 31, 2017 — Access to Stephen's Gap requires a permit from SCCI. Definitely get one before entering, and also toss them a few bucks. This is a gorgeous spot and its preservation is really important.
From the trailhead, I followed the short, obvious trail that leads straight to the mouth of Stephen's Gap Cave. You can scramble down into the cave on Class 2 boulders, but I brought a rope and would re-ascend using the standard hiking route. I rappelled into a hole in the ceiling of the cave, about 150 feet long. Rappelling is not necessary to enjoy this ridiculously gorgeous spot, but it did make it more fun.
