You can do this trail clockwise or anti-clockwise. The majority of the people follow the trail clockwise because it includes parts that can be steep and tricky and are best to be done going up and not going down. We did the trail anti-clockwise and I can confirm it is harder because you have a hard hike/climb and a very tough descend; furthermore, way fewer people go up following the trail anti-clockwise so you really need to have a good sense of orientation otherwise it's easy to get lost.
