Huge angled boulder that you can see from the valley below. It can be climbed with care, but is polished these days.

The south ridge is the easier way to reach the top of Tryfan, but it still has it's moments near the top.

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.
