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.

An interesting find on this peaceful trail is an old school bus. Originally used by logging companies to transport crews to work sites on the mountain, the bus was left abandoned and stripped of its engine and tires by 1954.
