Return description in North Wales Rock a bit misleading. Go up to the top of the small quarry where the quarry track heads inland towards some telegrph poles which lead up to a col, as you near the col you join a major track which leads you back down to Trefor, it's an hours walk. Do not underestimate this route, it is a big day out with very tricky route finding, testing grassy mantleshelves, good exposure, think in terms of a proper alpine route.
