Carefully wending my way over and around boulders, I climbed down off the trail, and then walked along the widest ledges, looking for an easier way back up. There was no easier way, so I decided to just take my time and enjoy the climb back up. It was a good workout and I did enjoy it very much.
Surprise! I found myself atop a tunnel that ran through the mountain I was on. A freight train tunnel along the shoreline.
One reward for climbing around was this view. I went way off the trail and climbed down over boulders to reach a place with a new view. In the distance you can see Sugarloaf Mountain across the river in Hudson Highlands State Park.
