Definitely underestimated this trail.  Very steep, rugged, crawling with your hands and knees kind of trail.  The first mile was very deceiving as it was fairly flat, then it started getting steeper with a few obstacles.  There was a point at which I realized I wasn't sure when exactly the trail ended and I started climbing up the side of this mountain with barely a visible trail.  The Wall is a completely different story.  You're going to need to actually CLIMB a rock wall.  The views from the top were spectacular.  The pain and agony on the descent were spectacular.  The entire hike was a spectacular.  And that's all I have to say about that.  This is the way.
