As this is a loop, it is functional in either the clockwise or counter clockwise direction.
Either direction gives a challenging downhill/uphill combo. Obstacles are minimal but the descent on the northern branch (Trail #14) is much looser and steeper - this can be a challenging descent for beginners.
The White Loop has been rerouted on the uphill (on Trail #15), so the blazes are sparse and many are faded (or just haven't been replaced yet). The new trail stays very close to old trail, old sections are blocked off by brambles so it is not difficult to stay on route, just trust your sense of direction.
