Skull Cave, isn't what most people expect. You are not supposed to get near it, it's blocked off for the most part. The story says that it used to be much larger, large enough for a horse to fit inside, but that people collapsed most of it over the years, as the limestone was brittle, so now it's much less of a cave and more of a hole in a rock. Many people will tell you it's not worth the hike, but you walk right past it to see so many other things, why not stop and check it out. It was a nice little stopping point for us to take a short hike break with the dogs, and watch a few horse and carriages go by!
