Featureless, flat moorland surrounds this subsidiary summit of Cyrniau Nod, part of the Hirnantau in the Berwyn range. The highest point, at 644.2 m, is just a tussock, and a small cairn stands a few metres from a track that continues to the pass between Cyrniau Nod and Y Groes Fagl. Views are extensive, and Foel Cedig is 1.9 km away.
