I labeled this trail as singletrack, but it's really kind of a mix of singletrack and wider-than-singletrack-but-not-really-doubletrack. Some areas of the trail get to be 4-6 feet wide, but don't think that makes this an easy ride.
In the direction I've posted, it starts as a fun rocky downhill section that has a good flow to it. A few of the corners are a little loose and rocky, especially in the summer months. For the most part though you can really rail the corners. There are some small rock drops, but nothing too technical or gnarly.
About halfway through the loop, you'll start the climb back up. It's not a particularly steep climb, though it gets fairly steep for brief periods throughout. It's the rocks that really make it tough. There is a pretty good line through most of the climb, but the rocks are always there. This trail really gives you a chance to work on controlling your cadence and power application to prevent loosing traction.
In the clockwise direction, this trail is pretty similar. It starts with a fun, flowy downhill and transitions into a long, tough climb. I think the downhill is a bit more fun counterclockwise, but it's also a tougher climb.
