I wish I could have given this trail 4-5 stars because the hike was awesome! I have to agree with Mark below, carry some protection and/or don't go alone, there were quite a few parts of the trail I didn't feel safe as there were a few shady characters on the trail. Overall it was well marked, rocky, rooty, hilly, a great challenge w/great views of rock formations and of the river and the Mary Campbell Cave was a sight to behold. My issues were the stench of sewage from the "falls" that are down river from the water treatment plant, then that the back half of the trail was closed which is elevated and away from the water and hikers have to turn around and return back the way we came which meant smelling that awful smell back to the trail head. Heartbreaking...
