If you like rocks and chunky trails you will love this one. If you're looking for a smooth flow trail, this is not it. Some roots, lots of rocks, some loose some embedded. I would say this is more of Blue/Black than a black diamond. Some good elevation change and just enough technical to keep you engaged. The trail is a jumping off point for some good routes in the Brainard area.
