This trail seems like it should be part of the B Trail, but it has it's own name for some reason. Perhaps, in the future, the trail designers will see this single anomaly and rename it or merge it with the B to conform with the standards set by all their other trails?
For now, the trail starts at the end of B Trail as C Trail crosses over. Simply ride down the gently dropping trail and under C Trail and it's cool overpass. Then the trail gets a bit steeper with a couple of jump options on the sides before meeting up with A Trail and B Trail.
