Plenty of people love to tackle the McKay Hollow Trail despite its difficulty. The trail drops steeply down the western ridge of Monte Sano Mountain, with great views of Blue Spring Falls, and heads down through imposing cliffs and boulders. O’Shaughnessy Point comes into view as the trail goes down and then up the hollow. The route also follows Blue Spring Creek along the bottom of the hollow. Trail Surface: Rock-covered trail on the sides of the hollow; dirt path along the creek.
