Dirty Deep is a flowy smooth trail that starts near the tower and heads down to the bottom of of Grand Deep area. The trail is supposed to be off-camber with minimal berms to make riding it fast more challenging, please leave it that way. When you get to the bottom, go across the gully and climb up the trail on the left, taking a right when you hit a dead end. You will arrive at the end of Grand Deep, where you take a right and climb up Gondwana.
