The summit is bare and rocky and marked with a cairn. The north and east face has large cliffs. A rock climb/extreme scramble known as the Cyfrwy Arete is found here. This arete is very steep and rope and rock climbing skills will be needed. To the west is Tyrrau Mawr and Craig-y-llyn, while to the south is Craig Cwm Amarch.[1]
