We were the last hikers down in the evening of 10/26/2018. We are fairly active people in our 40s. For it to be rated as moderate isn't quite accurate. I've climbed peaks and trails (NM, AZ, MT, the Smokies, the Rockies, etc) that were simpler than and more moderate than this one. It was tough but enjoyable. It's definitely one of the most scenic hikes I've ever been.
The park closed the trail that evening due to bear activity. We only saw bear scats. Two days later, I did see a bear about 20 feet from me when we stopped by on our way home so I can take a picture of the closure sign. I didn't know it was off to the side scrounging for food. It was scary although I didn't run, just walked slowly back to our car. It didn't even look at me. I look forward to going back, not for the bears but for the scenery.
