About half the trail is on a road. Nice once you get into the woods.

What's not love! I could see how someone could get off the trail. There are some foot paths leading off that if I wasn't paying attention could have taken a wrong turn. The views were great and it was a lot of fun.

A nice slow and steady hike. Can't bring your dog which is a bummer.

Beautiful once you get to the lake. So peaceful. Seems the parking lot is usually full when it's nice out, but you get to the lake and nobody is there. We come here often. Close to home and it's a really nice hike.
