Hiking among towering moss-covered rocks with small caves to either side is a bit creepy, but it's worth the visit! It's not very well marked, but you have stairs to one side if you don't want to walk in between the rocks. There's a wooden fence blocking off an unsafe path between rocks, so if you see that, you're in the right place.
