Well, the vino quickly wore off and the endorphins kicked in, as the initial part of the hike was nearly completely vertical. It is a bit more challenging than I expected, and several hikers gave up and turned back, but after the first hour, I felt pot-committed and was not about to give up. The path is so narrow that, in most places, for someone to pass in either direction, one person has to kiss the wall. That sort of proximity builds an easy camaraderie that is undeniably encouraging.
