Heard about this trail from one of my co-workers and immediately looked it up online. After looking it up I knew I had to do this trail. The trail is so nice and we would have gone further if we hadn't gone the wrong way and wasted 30min walk the opposite direction of the trail.
Its rocky so brake out the sneakers, but the views and breezes are great. Now that its the hight of summer I think its to hot for day time hikes but early morning my be decent. The views are beautiful and the history of it is amazing.
For the outdoors types I would highly recommend but bring plenty of water and sunscreen. I can't wait to go back (when the weather is more bearable,though.) Opps, almost forgot watch out for bats in the tunnels!!!
