Summary: This is a fun hike into a dark and spooky grotto, with house size boulders, caves, waterfalls, steep walls, and a real sense of mystery. The hike into the grotto is pleasant, but not spectacular. Once in the grotto you can have a blast scrambling around on the boulders of you have a good sense of balance and are careful. Lots of fun!
