Rail Trail is quite level and well defined. The Admiral's Loop is also relatively easy to follow, at least the trail with the yellow markers. The views are spectacular and well worth the effort to get there. It is however a rigorous hike not meant for anyone not in decent shape. Take plenty of water and pictures. Took approximately 5.5 hours including walk from parking lot and back.
great trail, with beautiful look offs. there is a main path that connects 3 different loop trails. the main path is great for biking and has spots to lock you bike up in front of the trails. as someone said before this trail is not for beginners or kids.
