Both trails should be run counter-clockwise.
The novice trail is marked by the green arrow. From the sign head left down a winding path with lightly banked corners, once you get into the trees the trail starts to weave more and the berms become steeper and tighter to help keep your speed up. Near the bottom of the hill will be a log bridge that can be bypassed if you don't feel comfortable taking it. The return path is a gentle climb with some dips to give you a bit of a break but be warned that there are two short bridges over runoff areas that are very narrow. Easy enough to step over if you don't feel confident riding them. You'll end with a short slightly steep climb along the dirt road you originally arrived on to get back to the trailhead allowing you to make another loop easily or go onto the intermediate trail.
The intermediate trail is marked by the blue arrow. This trail is marginally more difficult by the presence of some rock gardens and a couple of jumps that can be taken slowly. Not all of the rock gardens can be bypassed but they're short and relatively easy to navigate. The first part of the trail is a tight technical section with banked corners, some of which are uphill and one corner is followed by a rock garden which can be difficult to cross if you don't carry enough speed. Once through the first wooded section the trail becomes a lot faster and flows a lot better, with a few jumps and nice berms on the high speed corners letting you whip round. Once you get toward the bottom of the hill there is a final jump that can be bypassed before a long climb that leads you back to the trailhead, you can turn right and do the novice loop or turn left for another lap of the intermediate loop.
