A very fine mountain that is the high point of the Carneddau range. These mountains are high, remote and so much quieter than the Glyderau or Snowdon. Fabulous walking country.

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.
