A wonderful spiky summit with fine views to Yr Wyddfa and into Ogwen Valley. The summit itself is a scramble over very large jumbled boulders.

Whilst the Gribin may not be Tryfan North Ridge or Bristly Ridge, it is still a worthy part of this route.

The village of Abergwyngregyn (often shortened to Aber) is on the north coast of Wales, a few miles east of Bangor. The Mound: Pen-y-Mwd is a substantial, steep-sided, sub-circular earthwork. It is a classic Motte, which is the high mound of a motte-and-bailey castle. It measures roughly 22 feet (6.7 meters) high. Motte and Bailey: Traces of a surrounding ditch and a potential Bailey (the outer defensive enclosure) to the south-east have been identified. The motte itself has never been excavated.

After the rest stop at Llyn Y Cwn we descend and pass the Devil's Kitchen (Twll Du) again. The descent is as strenuous as the climb. The path, as far as can be seen, is quite steep in places. Then it becomes a matter of paying attention, scrambling and searching for the next section of the path. This is not such an easy part of the route. You have to use your hands and feet to conquer the steepest parts.
