This trail is just under 8 miles from parking lot to parking lot. We went clockwise, down Dismal and up Naturaland trail. There’s a cool foot bridge at the bottom. The Naturaland trail between the two bridges can be a little brutal, very steep, but not bad. My wife and I had no trouble with trekking poles, though there are a few scrambles. Take bug spray, food, and 2-3 liters of water. We did the loop in about 4:45, taking our time and stopping for lunch.
